SmartNanotubes Technologies, a German startup that has developed the world’s first micro power multi-channel gas detector chip for the mass market, has raised € 2.4 million in its Series A funding round. Lead investors are Cottonwood Technology Fund and duotec GmbH. Game changer in the gas sensor market SmartNanotubes Technologies, based near Dresden, operates on the principle of an electronic nose similar to the array of receptors in the human nose. Current gas sensor arrays are expensive, large in size, and characterized by low sensitivity and high power consumption. The carbon nanotubes chips of SmartNanotubes, however, are highly sensitive, energy-efficient, compact, and low-cost. SmartNanotubes is a game-changer in the gas sensor market as its chips can measure multiple gases while most existing technologies can only detect one gas at a time. Product quality, safety, and security In a team of four people, Dr. Viktor Bezugly and Dr. Birte Sönnichsen co-founded SmartNanotubes in the summer of 2020 after a three-year know-how transfer project at LifeScience Inkubator (LSI). Bezugly started his research on carbon nanotubes at DresdenUniversity of Technology twelve years ago. “I’m delighted to make my research available to the public by setting up this company. As of now, our target markets include product quality in materials, food, and medical applications,’’ said Viktor Bezugly. “Other areas include safety and security in transport, consumer goods, and manufacturing through the early detection and identification of volatile organic compounds (VOCs) and hazardous gases. Moreover, SmartNanotubes can control air quality, for example in industrial environments such as cleanrooms.” Multiple product lines and markets In its previous seed round, SmartNanotubes received support from LSI Pre-Seed-FoTechnologiegründerfonds Sachsen (TGFS), TUDAG TU Dresden Aktiengesellschaft, and a private investor. The current investment round is led by Cottonwood Technology Fund and German corporate duotec GmbH and complemented by Mittelständische Beteiligungsgesellschaft Sachsen. “We first met SmartNanotubes two years ago at the High-Tech Venture Days in Dresden. At the same time, we received a recommendation from a large corporate about its outstanding technology,’’ said Alain le Loux, General Partner of Cottonwood Technology Fund. “SmartNanotubes is the perfect example of a deep tech company with disruptive innovation. It is truly rewarding to help them in the pre-customer and pre-revenue stage with launching their technology in the global market. In particular, because SmartNanotubes offers the possibility of technology-selling in multiple markets and product lines.’’ For duotec, the investment in SmartNanotubes is a continuation of their innovation strategy. “We are expanding our portfolio of expertise through innovative and disruptive technologies,” said Arthur Rönisch, Managing Director and CIO of duotec. “This novel sensor technology means we are ahead of the competition by more than just a nose, literally. Together with our customers, we will incorporate this know-how into products.” “We are very excited to have both Cottonwood and duotec on board as our newest investors,’’ said co-founder Dr. Birte Sönnichsen. “duotec is well known as a very professional electronics production partner. And Cottonwood brings us – besides their deep-tech startup experience – a global network of relevant corporates including Asia and the United States”.

Breakthrough regulates household temperature without consuming natural gas or electricity Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cools during the summer without consuming natural gas or electricity. Research findings reported in the journal Science point to a groundbreaking technology that outperforms commercial cool-roof systems in energy savings. “Our all-season roof coating automatically switches from keeping you cool to warm, depending on outdoor air temperature. This is energy-free, emission-free air conditioning and heating, all in one device,” said Junqiao Wu, a faculty scientist in Berkeley Lab’s Materials Sciences Division and a UC Berkeley professor of materials science and engineering who led the study. Today’s cool roof systems, such as reflective coatings, membranes, shingles, or tiles, have light-colored or darker “cool-colored” surfaces that cool homes by reflecting sunlight. These systems also emit some of the absorbed solar heat as thermal-infrared radiation; in this natural process known as radiative cooling, thermal-infrared light is radiated away from the surface. The problem with many cool-roof systems currently on the market is that they continue to radiate heat in the winter, which drives up heating costs, Wu explained. “Our new material – called a temperature-adaptive radiative coating or TARC – can enable energy savings by automatically turning off the radiative cooling in the winter, overcoming the problem of overcooling,” he said. A roof for all seasons Metals are typically good conductors of electricity and heat. In 2017, Wu and his research team discovered that electrons in vanadium dioxide behave like metal to electricity but an insulator to heat – in other words, they conduct electricity well without conducting much heat. “This behavior contrasts with most other metals where electrons conduct heat and electricity proportionally,” Wu explained. Vanadium dioxide below about 67 degrees Celsius (153 degrees Fahrenheit) is also transparent to (and hence not absorptive of) thermal-infrared light. But once vanadium dioxide reaches 67 degrees Celsius, it switches to a metal state, becoming absorptive of thermal-infrared light. This ability to switch from one phase to another – in this case, from an insulator to metal – is characteristic of what’s known as a phase-change material. To see how vanadium dioxide would perform in a roof system, Wu and his team engineered a 2-centimeter-by-2-centimeter TARC thin-film device. TARC “looks like Scotch tape, and can be affixed to a solid surface like a rooftop,” Wu said. In a key experiment, co-lead author Kechao Tang set up a rooftop experiment at Wu’s East Bay home last summer to demonstrate the technology’s viability in a real-world environment. A wireless measurement device set up on Wu’s balcony continuously recorded responses to changes in direct sunlight and outdoor temperature from a TARC sample, a commercial dark roof sample, and a commercial white roof sample over multiple days. How TARC outperforms in energy savings The researchers then used data from the experiment to simulate how TARC would perform year-round in cities representing 15 different climate zones across the continental U.S. Wu enlisted Ronnen Levinson, a co-author on the study who is a staff scientist and leader of the Heat Island Group in Berkeley Lab’s Energy Technologies Area, to help them refine their model of roof surface temperature. Levinson developed a method to estimate TARC energy savings from a set of more than 100,000 building energy simulations that the Heat Island Group previously performed to evaluate the benefits of cool roofs and cool walls across the United States. Finnegan Reichertz, a 12th-grade student at the East Bay Innovation Academy in Oakland who worked remotely as a summer intern for Wu last year, helped to simulate how TARC and the other roof materials would perform at specific times and on specific days throughout the year for each of the 15 cities or climate zones the researchers studied for the paper. The researchers found that TARC outperforms existing roof coatings for energy saving in 12 of the 15 climate zones, particularly in regions with wide temperature variations between day and night, such as the San Francisco Bay Area, or between winter and summer, such as New York City. “With TARC installed, the average household in the U.S. could save up to 10% electricity,” said Tang, who was a postdoctoral researcher in the Wu lab at the time of the study. He is now an assistant professor at Peking University in Beijing, China. Standard cool roofs have high solar reflectance and high thermal emittance (the ability to release heat by emitting thermal-infrared radiation) even in cool weather. According to the researchers’ measurements, TARC reflects around 75% of sunlight year-round, but its thermal emittance is high (about 90%) when the ambient temperature is warm (above 25 degrees Celsius or 77 degrees Fahrenheit), promoting heat loss to the sky. In cooler weather, TARC’s thermal emittance automatically switches to low, helping to retain heat from solar absorption and indoor heating, Levinson said. Findings from infrared spectroscopy experiments using advanced tools at Berkeley Lab’s Molecular Foundry validated the simulations. “Simple physics predicted TARC would work, but we were surprised it would work so well,” said Wu. “We originally thought the switch from warming to cooling wouldn’t be so dramatic. Our simulations, outdoor experiments, and lab experiments proved otherwise – it’s really exciting.” The researchers plan to develop TARC prototypes on a larger scale to further test its performance as a practical roof coating. Wu said that TARC may also have the potential as a thermally protective coating to prolong battery life in smartphones and laptops, and shield satellites and cars from extremely high or low temperatures. It could also be used to make temperature-regulating fabric for tents, greenhouse coverings, and even hats and jackets. Co-lead authors of the study were Kaichen Dong and Jiachen Li. The Molecular Foundry is a nanoscience user facility at Berkeley Lab. This work was primarily supported by the DOE Office of Science and a Bakar Fellowship. The technology is available for licensing and collaboration. If interested, please contact Berkeley Lab’s Intellectual Property Office, ipo@lbl.gov.

Wireless, fully implantable device gives temporary pacing without requiring removal. Researchers at Northwestern and George Washington universities (GW) have developed the first-ever transient pacemaker — a wireless, battery-free, fully implantable pacing device that disappears after it’s no longer needed. The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components of the pacemaker are biocompatible and naturally absorb into the body’s biofluids over the course of five to seven weeks, without needing surgical extraction. The device wirelessly harvests energy from an external, remote antenna using near-field communication protocols — the same technology used in smartphones for electronic payments and in RFID tags. This eliminates the need for bulky batteries and rigid hardware, including wires (or leads). Not only can leads introduce infections, but they also can become enveloped in scar tissue, causing further damage when removed. The study was published in the journal Nature Biotechnology. The paper demonstrates the device’s efficacy across a series of large and small animal models. “Hardware placed in or near the heart creates risks for infection and other complications,” said Northwestern’s John A. Rogers, who led the device’s development. “Our wireless, transient pacemakers overcome key disadvantages of traditional temporary devices by eliminating the need for percutaneous leads for surgical extraction procedures — thereby offering the potential for reduced costs and improved outcomes in patient care. This unusual type of device could represent the future of temporary pacing technology.” “Sometimes patients only need pacemakers temporarily, perhaps after an open heart surgery, heart attack, or drug overdose,” said Dr. Rishi Arora, a cardiologist at Northwestern Medicine who co-led the study. “After the patient’s heart is stabilized, we can remove the pacemaker. The current standard of care involves inserting a wire, which stays in place for three to seven days. These have potential to become infected or dislodged.” “The transient electronics platform opens an entirely new chapter in medicine and biomedical research,” said GW’s Igor Efimov, who co-led the study with Rogers and Arora. “The bioresorbable materials at the foundation of this technology make it possible to create a whole host of diagnostic and therapeutic transient devices for monitoring progression of diseases and therapies, delivering electrical, pharmacological, cell therapies, gene reprogramming and more.” Rogers is the Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering, Biomedical Engineering and Neurological Surgery in the McCormick School of Engineering and Feinberg School of Medicine and the director of the Querrey Simpson Institute for Bioelectronics. Arora is a professor of medicine at Feinberg and co-director of the Center for Arrhythmia Research. Efimov is the Alisann and Terry Collins Professor of Biomedical Engineering at GW. Ditching restrictive, risky leads Currently, to set up temporary pacing after open-heart surgery, surgeons must sew on temporary pacemaker electrodes on the heart muscle during surgery. These have leads that exit the front of a patient’s chest, connecting to an external pacing box that delivers a current to control the heart’s rhythm. When the temporary pacemaker is no longer needed, physicians remove the pacemaker electrodes. Although uncommon, potential complications of implanted temporary pacemakers include infection, dislodgement, torn or damaged tissues, bleeding, and blood clots. With Northwestern and GW’s transient pacemaker, surgeons and patients can sidestep this potentially risky procedure. The fully implantable device is light and thin — 250 microns thick and weighing less than half a gram. Soft and flexible, it encapsulates electrodes that softly laminate onto the heart’s surface to deliver an electrical pulse. “Instead of using wires that can get infected and dislodged, we can implant this leadless biocompatible pacemaker,” Arora said. “The circuitry is implanted directly on the surface of the heart, and we can activate it remotely. Over a period of weeks, this new type of pacemaker ‘dissolves’ or degrades on its own, thereby avoiding the need for physical removal of the pacemaker electrodes. This is potentially a major victory for post-operative patients. “With further modifications, it eventually may be possible to implant such bioresorbable pacemakers through a vein in the leg or arm,” he added. “In this instance, it also may be possible to provide temporary pacing to patients who have suffered a heart attack or to patients undergoing catheter-based procedures, such as transcatheter aortic valve replacement.” Prioritizing patient comfort Northwestern Medicine cardiac surgeon Dr. Duc Thinh Pham, who was not involved with the research, imagines a transient pacemaker undoubtedly would make his patients more comfortable. With current pacemakers, patients often feel discomfort for days after the leads are inserted. Then, they must limit their movements and activities in order to prevent the leads from dislodging. “This transient pacemaker is brilliant,” said Pham, who has performed more than 2,000 cardiac surgeries throughout his career. “In addition to addressing the primary issue of occasional post-cardiac surgery patients needing temporary pacing due to blockages or arrhythmias, the device addresses the secondary issue of patient comfort, ability to move freely and rehabilitate. If successful, this device will greatly improve a patient’s postoperative course.” Disappearing act This is the second example of bioresorbable electronic medicine from the Rogers lab, which has been studying transient electronics for over a decade. In 2018, Rogers and colleagues demonstrated the world’s first bioresorbable electronic device — a biodegradable implant that speeds nerve regeneration. The team’s bioresorbable devices are completely harmless — similar to absorbable stitches. After fully degrading, the devices completely disappear through the body’s natural biological processes. “There is clearly a need for better temporary cardiac pacemakers,” said Dr. Bradley Knight, the Chester C. and Deborah M. Cooley Distinguished Professor of Cardiology at Feinberg and coauthor of the study. “When I first learned about the bioresorbable nerve stimulator, I contacted Professor Rogers to explore the possibility of using this technology to pace the heart. He had already started working with Dr. Efimov to develop a small version of a bioresorbable pacemaker as a proof of concept. We then worked with both teams to develop a larger version of a bioresorbable, leadless, cardiac pacemaker that could be effective on a human scale. It’s a great example of what we can create at Northwestern by bridging the expertise in engineering and medicine.” Depending on the patient, a temporary pacemaker might be needed anywhere from a couple of days to several weeks. By varying the composition and thickness of the materials in the device, Rogers’ team can control the precise number of days it remains functional before dissolving. “We build these devices out of different types of safe, bioresorbable materials and in optimized architectures to ensure stable operation over a time period somewhat longer than is clinically necessary,” Rogers said. “We can tailor the devices to address a broad spectrum of relevant lifetimes. Transient technologies, in general, could someday provide therapy or treatment for a wide variety of medical conditions — serving, in a sense, as an engineering form of medicine.” The paper, “Fully bioresorbable, leadless, battery-free cardiac pacemaker,” was supported by the Leducq Foundation (RHYTHM award), National Institutes of Health (award numbers R01-HL141470, R01-HL140061, and R01-HL125881), the American Heart Association (award number 19PRE34380781, AF SFRN), the National Science Foundation (award number 1842165) and the Ford Foundation. The paper’s co-first authors are Yeon Sik Choi, Rose Yin, Jahyun Koo, and Anna Pfenniger.

pH sensor S-301 PET 190 μm Foil sensor for pH monitoring pH 4.5 – pH 9 The S-301 is a foil sensor with electrodes for electrochemical pH determination of samples. The accensors pH-sensor consists of two electrodes (a pH-sensitive and a non-sensitive Ag/AgCl reference electrode) on a transparent PET foil. The readings are taken by measuring the open circuit potential/voltage between both electrodes. Potential (E) and pH have a linear relationship (between the operating range of pH 4.5 to pH 9) so the pH of an unknown analyte solution can be calculated using the pre-determined slope and an offset E value (E0 determined by measuring the potential in a calibration buffer of known pH). The reference electrode and overall sensor can be used in analytes with different chloride concentrations thanks to a solid-state electrolyte layer. Once used, the sensor must be kept hydrated for further application and not allowed to dry out. The foil carrier is made of transparent PET material and the sensor is flexible, although care should be taken do not to bend the electrode spots. A connection between sensor and measurement electronics can be established via accensors connect or ZiF-connector. Contact pads are covered with oxidation protection. The data given refers to the use of the sensor in combination with the ACO accensors D-300 measurement device and our accensors iOS application. The measuring output will display the measured potential (in mV) or if the sensor is calibrated (one point software calibration at 21 oC or two-point at other temperature) output can be given as pH. Note that this sensor is somewhat light-sensitive, and the long-term stability (during use) will be reduced when used in brightly lit conditions. pH sensor S-302 PET 190 μm Foil sensor for pH monitoring pH 5.5 – pH 10 The S-302 is a foil sensor with electrodes for electrochemical determination of pH of samples.

FaceBit can monitor the wearer’s health, sense heartbeat through the face. Northwestern University engineers have developed a new smart sensor platform for face masks that they are calling a “Fitbit for the face.” Dubbed “FaceBit,” the lightweight, quarter-sized sensor uses a tiny magnet to attach to any N95, cloth, or surgical face mask. Not only can it sense the user’s real-time respiration rate, heart rate, and mask wear time, it also may be able to replace cumbersome tests by measuring mask fit. All this information is then wirelessly transmitted to a smartphone app, which contains a dashboard for real-time health monitoring. The app can immediately alert the user when issues — such as elevated heart rate or a leak in the mask — unexpectedly arise. The physiological data also could be used to predict fatigue, physical health status, and emotional state. Although a tiny battery powers the device, FaceBit is designed to harvest energy from any variety of ambient sources — including the force of the user’s breathing, motion, and heat from a user’s breath as well as from the sun. This extends the sensor’s battery life, lengthening the time between charges. “We wanted to design an intelligent face mask for health care professionals that do not need to be inconveniently plugged in during the middle of a shift,” said Northwestern’s Josiah Hester, who led the device development. “We augmented the battery’s energy with energy harvesting from various sources, which means that you can wear the mask for a week or two without having to charge or replace the battery.” The research was published last week in the Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies. In the study, researchers found FaceBit’s accuracy was similar to clinical-grade devices, and the battery lasted longer than 11 days between charges. More information is available at facebit health. Hester is an assistant professor of computer science, computer engineering, and electrical engineering and the Breed Junior Professor of Design at Northwestern’s McCormick School of Engineering. Approximating the fit test Before designing FaceBit, Hester and his collaborators first interviewed doctors, nurses, and medical assistants to better understand their needs for smart face masks. In a series of surveys, all clinicians indicated that the quality of mask fit was most important — especially when working directly with patients with viral infections. To ensure their N95 masks are properly sealed to their faces, health care workers periodically undergo a 20-minute “fit test.” During this process, health care workers first put on an N95 respirator followed by a clear hood over their entire head. Another worker then pumps either sweet or bitter aerosol mists into the hood. The concentration of the aerosol is gradually increased inside the hood until it can be detected by the person wearing the respirator. If the wearer tastes bitter or sweet before a certain number of aerosol pumps, then the mask is not properly sealed. Although Hester’s FaceBit cannot yet replace this cumbersome process — which is a long-standing challenge in the medical industry — it can ensure the mask retains proper fit between testing events. If the mask becomes loose throughout the day or if the user bumps the mask during an activity, for example, FaceBit can alert the wearer. “If you wear a mask for 12 hours or longer, sometimes your face can become numb,” Hester said. “You might not even realize that your mask is loose because you cannot feel it or you are too burnt out to notice. We can approximate the fit-testing process by measuring mask resistance. If we see a sudden dip in resistance, that indicates a leak has formed, and we can alert the wearer.” Face-centric bio-sensing But the FaceBit can assess more than mask fit — it also can monitor the person wearing the mask in real-time. By gathering various physiological signals — such as heart and respiratory rates — FaceBit can help wearers better understand their own bodies in order to make beneficial health decisions. All health information, including mask, fit and wear time, are displayed on the accompanying smartphone app. According to Hester, every time a person’s heart beats, their head moves an imperceptibly tiny amount. FaceBit can sense that subtle motion — and differentiate it from other motions — in order to calculate heart rate. “Your heart is pushing a lot of blood through the body, and the ballistic force is quite strong,” Hester said. “We were able to sense that force as the blood travels up a major artery to the face.” Because stressful events can elicit physiological responses, including rapid breathing, FaceBit can use that information to alert the user to take a break, go for a walk or take some deep breaths to calm down. Hospital systems also could use this data to optimize shift and break schedules for their workers. And because heart rate and respiration rate are so tightly entangled with each other, having the ability to effortlessly monitor both could open new research possibilities. Battery-free future An expert in sustainable, battery-free technology, Hester hopes his team or others eventually will be able to make FaceBit completely battery free. Now, the wearer’s breathing and movements or the sun can extend the battery-freethe battery’s life. But, in the future, harvested thermal and kinetic energy could solely power the device. Although his team evaluated the device on volunteers in real-world scenarios, Hester said FaceBit still needs to undergo clinical trials and validation. The team released the project as open source and open hardware so others can build and validate the device. “FaceBit provides the first step toward practical on-face sensing and inference, and provides a sustainable, convenient, comfortable option for general health monitoring for COVID-19 frontline workers and beyond,” Hester said. “I’m really excited to hand this off to the research community to see what they can do with it.” The project, “FaceBit: Smart Face Masks Platform,” was supported by the National Science Foundation’s Grants for Rapid Response Research for addressing the COVID-19 pandemic (award number CNS-2032408). FaceBit was a collaboration with Nabil Alshurafa, assistant professor of preventative medicine in Northwestern University Feinberg School of Medicine and of computer science in McCormick.

The new substance is the result of a feat thought to be impossible: polymerizing a material in two dimensions. Using a novel polymerization process, MIT chemical engineers have created a new material that is stronger than steel and as light as plastic, and can be easily manufactured in large quantities. The new material is a two-dimensional polymer that self-assembles into sheets, unlike all other polymers, which form one-dimensional, spaghetti-like chains. Until now, scientists had believed it was impossible to induce polymers to form 2D sheets. Such a material could be used as a lightweight, durable coating for car parts or cell phones, or as a building material for bridges or other structures, says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT and the senior author of the new study. “We don’t usually think of plastics as being something that you could use to support a building, but with this material, you can enable new things,” he says. “It has very unusual properties and we’re very excited about that.” The researchers have filed for two patents on the process they used to generate the material, which they describe in a paper appearing today in Nature. MIT postdoc Yuwen Zeng is the lead author of the study. Two dimensions Polymers, which include all plastics, consist of chains of building blocks called monomers. These chains grow by adding new molecules onto their ends. Once formed, polymers can be shaped into three-dimensional objects, such as water bottles, using injection molding. Polymer scientists have long hypothesized that if polymers could be induced to grow into a two-dimensional sheet, they should form extremely strong, lightweight materials. However, many decades of work in this field led to the conclusion that it was impossible to create such sheets. One reason for this was that if just one monomer rotates up or down, out of the plane of the growing sheet, the material will begin expanding in three dimensions and the sheet-like structure will be lost. However, in the new study, Strano and his colleagues came up with a new polymerization process that allows them to generate a two-dimensional sheet called a polyamide. For the monomer building blocks, they use a compound called melamine, which contains a ring of carbon and nitrogen atoms. Under the right conditions, these monomers can grow in two dimensions, forming disks. These disks stack on top of each other, held together by hydrogen bonds between the layers, which make the structure very stable and strong. “Instead of making a spaghetti-like molecule, we can make a sheet-like molecular plane, where we get molecules to hook themselves together in two dimensions,” Strano says. “This mechanism happens spontaneously in solution, and after we synthesize the material, we can easily spin-coat thin films that are extraordinarily strong.” Because the material self-assembles in solution, it can be made in large quantities by simply increasing the quantity of the starting materials. The researchers showed that they could coat surfaces with films of the material, which they call 2DPA-1. “With this advance, we have planar molecules that are going to be much easier to fashion into a very strong, but extremely thin material,” Strano says. Light but strong The researchers found that the new material’s elastic modulus — a measure of how much force it takes to deform a material — is between four and six times greater than that of bulletproof glass. They also found that its yield strength, or how much force it takes to break the material, is twice that of steel, even though the material has only about one-sixth the density of steel. Matthew Tirrell, dean of the Pritzker School of Molecular Engineering at the University of Chicago, says that the new technique “embodies some very creative chemistry to make these bonded 2D polymers.” “An important aspect of these new polymers is that they are readily processable in solution, which will facilitate numerous new applications where a high strength to weight ratio is important, such as new composite or diffusion barrier materials,” says Tirrell, who was not involved in the study. Another key feature of 2DPA-1 is that it is impermeable to gases. While other polymers are made from coiled chains with gaps that allow gases to seep through, the new material is made from monomers that lock together like LEGOs, and molecules cannot get between them. “This could allow us to create ultrathin coatings that can completely prevent water or gases from getting through,” Strano says. “This kind of barrier coating could be used to protect metal in cars and other vehicles, or steel structures.” Strano and his students are now studying in more detail how this particular polymer is able to form 2D sheets, and they are experimenting with changing its molecular makeup to create other types of novel materials.

Purpose to bring low-cost manufacturing of flexible microLED and nanoLED displays to market Download as PDF Silicon Valley, CA., February 02, 2022 – SmartKem, Inc. (OTCQB: SMTK), a company seeking to reshape the world of electronics with a revolutionary new organic semiconductor platform that enables a new generation of displays, and Nanosys, Inc., the leader in developing and delivering quantum dot and microLED technology, announced today that they have entered into a joint development agreement to work together on a new generation of low-cost solution printed microLED and quantum dot materials for advanced displays. Both companies believe that combining fully solution printed displays using SmartKem’s high-performanceorganic semiconductor formulations with TFT interlayer materials using Nanosys’s microLED and quantum dot nanoLED technologies should result in the creation of a new class of low power, robust, flexible, lightweight displays. Initial validation work on the equipment, processes and materials readiness has already occurred. Commenting on today’s announcement, Ross Young, Display Supply Chain Consultants (DSCC) CEO, notes, “There are significant synergies between these two companies and their joint development work has the potential to accelerate commercialization opportunity for both companies.” Ian Jenks, Chairman and CEO of SmartKem, said, “We have been working on the latest generation organic thin-film transistor (OTFT) technology for many years and have validated its readiness and availability for enabling the manufacturing of displays using advanced emitters such as microLEDs and quantum dot nanoLEDs from Nanosys.” “We are delighted to work with SmartKem on this novel backplane technology for displays. We believe that display makers are eager to utilize microLEDs and quantum dot nanoLED materials for new display applications in a high-throughput and cost-efficient manner. If our joint development work is successful, will have access to a holistic technology solution that meets their needs,” said Jason Hartlove, CEO and President of Nanosys. The joint development agreement contemplates that through the application of its unique TRUFLEX® technology, SmartKem will provide OTFT backplanes to enable the manufacture of microLED displays using Nanosys’ microLED and electroluminescent quantum dot nanoLED technologies. TRUFLEX® materials have been developed for standard process equipment sets and have the benefit of both lower material and equipment costs than traditional alternatives such as LTPS. SmartKem believes that this makes high performance and stable display backplane technology accessible to manufacturers at a lower capital cost compared to inorganic TFT technology.
