Group of researchers at the University of Pennsylvania, Drexel University, Corporal Michael J. Crescenz VA Medical Center & St. Jude Children’s Research Hospital have published in Science Translational Medicine "MXene-infused bioelectronic interfaces for multiscale electrophysiology and stimulation" a flexible MXene electrode that record brain activity, electromyography to measure muscle activation, electrocardiography to monitor heart activity, and electrooculography to map eye movement. "Soft bioelectronic interfaces for mapping and modulating excitable networks at high resolution and at a large scale can enable paradigm-shifting diagnostics, monitoring, and treatment strategies. Yet, current technologies largely rely on materials and fabrication schemes that are expensive, do not scale, and critically limit the maximum attainable resolution and coverage. Solution processing is a cost-effective manufacturing alternative, but biocompatible conductive inks matching the performance of conventional metals are lacking. Here, we introduce MXtrodes, a class of soft, high-resolution, large-scale bioelectronic interfaces enabled by Ti3C2 MXene (a two-dimensional transition metal carbide nanomaterial), and scalable solution processing. We show that the electrochemical properties of MXtrodes exceed those of conventional materials and do not require conductive gels when used in epidermal electronics. Furthermore, we validate MXtrodes in applications ranging from mapping large-scale neuromuscular networks in humans to cortical neural recording and microstimulation in swine and rodent models." "Electrodes were fabricated in planar or three-dimensional forms and were applied to the skin of volunteers for use with electroencephalography to record brain activity, electromyography to measure muscle activation, electrocardiography to monitor heart activity, and electrooculography to map eye movement. The electrode arrays could also be implanted in pigs and rats for intraoperative monitoring and stimulation of the brain and showed compatibility with magnetic resonance and computed tomography imaging. These flexible interfaces have potential clinical utility for multiscale epidermal sensing and neuromodulation."

Researchers from Penn State's Department of Engineering Science and Mechanics have published ACS Applied Materials & interfaces paper "Strain-Tunable Microfluidic Devices with Crack and Wrinkle Microvalves for Microsphere Screening and Fluidic Logic Gates" highlighting a simple, low-cost, efficient way to fabricate strain-tunable elastomeric micropatterns as microvalves in a microfluidic device. “The crack microvalves are closed before stretching but open as the tensile strain increases, whereas the wrinkle microvalves exhibit the opposite trend. The microfluidic device with crack and wrinkle microvalves is demonstrated for microparticle screening and fluidic logic operation in a programmable manner. The applied tensile strain changes the width and depth of the crack microvalves to control the selective transport of microparticles of different sizes. When the crack and wrinkle microvalves are integrated into the single microfluidic device, the fluid can be modulated to flow through the microvalves in a manner that represents the operation of the OR or AND logic gates. These controllable valves to adjust the reaction time and volume represent a viable path toward large-scale integration for potential applications in multiliquid, multistep sample preparation, and reagent processing. The programmable microfluidic system demonstrated in this study opens up additional opportunities to complement the prior reports in applications ranging from biomedicine and organ-on-chips to drug delivery and reagent mixing. However, PDMS is prone to swelling in many organic solvents. Although the application of the device with PDMS is limited (aqueous solutions), the concept from this study can be applied to the other soft materials that are stable in the target organic solvent.”

A team of researchers at the Institute of Scientific and Industrial Research "SANKEN" at Osaka University and Joanneum Research has succeeded in precisely tune the electronic properties of organic polymer by exposing it to UV light. Their work "Heterogeneous Functional Dielectric Patterns for Charge-Carrier Modulation in Ultraflexible Organic Integrated Circuits" can help in commercializing the flexible electronics that are used in healthcare monitoring and data processing. "While the integrated circuits inside your smartphone are quite impressive, they lack certain important features. Because the electronics are silicon-based, they are very rigid, both in the literal sense of being inflexible, as well as having chemical properties that are not easily altered. Newer devices, including OLED displays, are made from carbon-based organic molecules with chemical properties that can be tuned by scientists to produce the most efficient circuits. However, controlling the characteristics of organic transistors usually requires the integration of complex structures made of various materials. The team has used UV light to precisely change the chemical structure of a dielectric polymer called PNDPE. The light breaks specific bonds in the polymer, which can then rearrange into new versions, or create crosslinks between strands. The longer the light is on, the more the polymer gets altered. By using a shadow mask, the UV light is applied to just the desired areas, tuning the circuit behavior. This method can pattern transistors of the desired threshold voltage with high spatial resolution using just a single material". "This study demonstrated the formation of the HFDP with the use of PNDPE as an ultrathin polymer gate dielectric to modulate the behavior of the charge carriers. The HFDP are obtained with a high-resolution of less than 18 µm. With the charge-carrier modulation via the photo-Fries rearrangement in the PNDPE gate dielectrics, the Vth of the PNDPE-based transistors were programmably controlled over a wide range from −1.5 to +0.2 V at an operational voltage of 2 V, indicating that both the enhancement and depletion transistors are arbitrarily fabricated. The modulated Vth remained unchanged over a period of 140 days during the LED exposure test and under a bias duration of 1800 s. The charge-carrier modulation was achieved by controlling the acceptor-like traps. The PNDPE forms dense and uniform gate dielectrics due to the catalytic ring-opening metathesis polymerization, resulting in ultrathin PNDPE films of a thickness of 14 nm. The transistor also exhibited high mechanical flexibility, in which the characteristics did not significantly vary even at a bending radius of 0.3 mm." "In the future, we may see smart versions of almost everything, from medicine bottles to safety vests. "Meeting the computational demands of 'the Internet of Things' will very likely require flexible electronic solutions," senior author Tsuyoshi Sekitani says. In particular, this technology can be applied to ming methods for ultra-lightweight wearable healthcare devices."O Sources https://www.eurekalert.org/news-releases/929046 https://www.sensortechresearch.com/articles/24808/tuning-flexible-circuits-with-light?rsst2id=1%2C4%2C8&utm_source=dlvr.it&utm_medium

Researchers from the Department of Electrical and Computer Engineering at Rutgers University-New Brunswick have created a biosensor microchip that does an accurate continuous readout of cortisol levels for real-time analysis and can be integrated into the wristband. They published their work in Science Advance "Single-step label-free nanowell immunoassay accurately quantifies serum stress hormones within minutes" "Cortisol and other stress hormones regulate many aspects of our physical and mental health, including sleep quality. High levels of cortisol can result in poor sleep, which increases stress that can contribute to panic attacks, heart attacks, and other ailments. Currently, measuring cortisol takes costly and cumbersome laboratory setups, so the Rutgers-led team looked for a way to monitor its natural fluctuations in daily life and provide patients with feedback that allows them to receive the right treatment at the right time. The researchers used the same technologies used to fabricate computer chips to build sensors thinner than a human hair that can detect biomolecules at low levels." "This study aims to bring laboratory-quality diagnostic to point of care and patient self-testing at a lower cost, and cortisol was chosen as a model analyte. The primary challenge faced by label-free technologies stems from measurement inconsistency, thus not being suitable for reliable quantification of molecular levels. The array structure of the sensor increases the probability of diffusion of the analyte and its subsequent binding to the sensor active area. Moreover, the sensor platform concentrates the electric field into the small volume of wells and reduces the noise from electrode polarization effect and solution conductivity, thereby producing a more accurate and reliable response. These systems can allow a continuous readout of cortisol levels for real-time analysis of patients subjected to stress and have great potential to be adapted to noninvasive cortisol measurement in desired biofluids such as human saliva and urine." "The use of nanosensors allowed us to detect cortisol molecules directly without the need for any other molecules or particles to act as labels,” said lead author Reza Mahmoodi, a postdoctoral scholar in the Department of Electrical and Computer Engineering at Rutgers University-New Brunswick. With technologies like the team’s new microchip, patients can monitor their hormone levels and better manage chronic inflammation, stress, and other conditions at a lower cost, said senior author Mehdi Javanmard, an associate professor in Rutgers’ Department of Electrical and Computer Engineering. “Our new sensor produces an accurate and reliable response that allows a continuous readout of cortisol levels for real-time analysis,” he added. “It has great potential to be adapted to non-invasive cortisol measurement in other fluids such as saliva and urine. The fact that molecular labels are not required eliminates the need for large bulky instruments like optical microscopes and plate readers, making the readout instrumentation something you can measure ultimately in a small pocket-sized box or even fit onto a wristband one day."

Engineers at Purdue University have published ACS Applied Materials & Interfaces paper “Ultrawhite BaSO4 Paints and Films for Remarkable Daytime Subambient Radiative Cooling” where they created the world's whitest paint that could eliminate the need for air conditioning and reflects 98.1% of solar radiation while also emitting infrared heat. “Radiative cooling is a passive cooling technology that offers great promises to reduce space cooling cost, combat the urban island effect, and alleviate the global warming. To achieve passive daytime radiative cooling, current state-of-the-art solutions often utilize complicated multilayer structures or a reflective metal layer, limiting their applications in many fields. Attempts have been made to achieve passive daytime radiative cooling with single-layer paints, but they often require a thick coating or show partial daytime cooling. In this work, we experimentally demonstrate remarkable full-daytime sub-ambient cooling performance with both BaSO4 nanoparticle films and BaSO4 nanocomposite paints. BaSO4 has a high electron band gap for low solar absorptance and phonon resonance at 9 μm for high sky window emissivity. With an appropriate particle size and a broad particle size distribution, the BaSO4 nanoparticle film reaches an ultrahigh solar reflectance of 97.6% and a high sky window emissivity of 0.96. During field tests, the BaSO4 film stays more than 4.5 °C below ambient temperature or achieves an average cooling power of 117 W/m2. The BaSO4-acrylic paint is developed with a 60% volume concentration to enhance the reliability in outdoor applications, achieving a solar reflectance of 98.1% and a sky window emissivity of 0.95. Field tests indicate similar cooling performance to the BaSO4 films. Overall, our BaSO4-acrylic paint shows a standard figure of merit of 0.77, which is among the highest of radiative cooling solutions while providing great reliability, convenient paint form, ease of use, and compatibility with the commercial paint fabrication process” Resources https://www.guinnessworldrecords.com/world-records/659962-whitest-paint https://www.purdue.edu/newsroom/releases/2021/Q3/purdue-record-for-the-whitest-paint-appears-in-latest-edition-of-guinness-world-records.html

LG Chem, one of the LG firms, has developed a cover window, using their innovative flexible coating material that can fold like plastic while keeping its strength, durability, and glass-like appearance. LG Chem’s cover window, which is a protective element over the screen and digitizers is referred to as a “Real Folding window” which is a few millimeters thick that can be folded more than 200,000 times before showing any signs of wear. What makes LG Chem’s foldable screen a significant breakthrough in the foldable smartphone industry, is that it can be folded both inwards and outwards allowing a vast of configurations on the screen displays using LG Chem’s innovative coating material. The Real Folding window is developed by coating both sides of PET film, a type of thin plastic, with micrometers thick LG Chem’s coated materials which could enhance the heat-resistance, mechanical properties of the plastic materials. This makes the cover window not only thinner than the existed tempered glass but also the same thickness without any cracking in the screen. “LG Chem is also developing technologies to produce a thin 'Real Folding Window' with only coating and not needing PET films.” "Unlike existing polyimide films and tempered glass-type materials, the cover window that applied LG Chem's new coating technologies will maximize flexibility, while also providing optimized solutions for foldable phones such as making improvements to chronic issues like fold impressions on the connecting part of the screen." Chang Do Ki (Vice President IT Materials Division. Advanced Materials) commented, "Through the Real Folding Window that we newly developed, we were able to take a step closer to resolving the pain points of customers, and we have already received proposals for joint projects from multiple clients." He added, "We will strengthen our partnerships with leading companies of the smartphone industry and expand our market starting with mobiles and going on to new foldable applications such as laptops and tablets."

Nanoengineers at the University of California San Diego published a Nature Communications paper "A self-sustainable wearable multi-modular E-textile bioenergy microgrid system", in which they have developed a "wearable microgrid" that harvests and stores energy from the human body to power small electronics. The wearable microgrid consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable, and can be screen printed onto clothing. “Despite the fast development of various energy harvesting and storage devices, their judicious integration into efficient, autonomous, and sustainable wearable systems has not been widely explored. Here, we introduce the concept and design principles of e-textile microgrids by demonstrating a multi-module bioenergy microgrid system. Unlike earlier hybrid wearable systems, the presented e-textile microgrid relies solely on human activity to work synergistically, harvesting biochemical and biomechanical energy using sweat-based biofuel cells and triboelectric generators, and regulating the harvested energy via supercapacitors for high-power output. Through energy budgeting, the e-textile system can efficiently power liquid crystal displays continuously or a sweat sensor-electrochromic display system in pulsed sessions, with half the booting time and triple the runtime in a 10-min exercise session. Implementing “compatible form factors, commensurate performance, and complementary functionality” design principles, the flexible, textile-based bioenergy microgrid offers attractive prospects for the design and operation of efficient, sustainable, and autonomous wearable system”

Perovsktie QDs are excellent. They are intrinsically tolerant of defects meaning that one can grow them at relatively low temperature and still the resultant defects and disorders do not strong affect the optical bandgap and, as such, the emission FWHM remains very narrow. In fact the emission full width half maximum is generally narrower than leading the lead Cd based QDs. In general, green PeQDs are more common now. They offer excellent absorption, meaning that they can even be used in color filters. Most, however, are using them in enhacement mode films. The set up, as described by Nanolumi, is shown below. Note that enhacement mode is already commercially common and Nanosys is the leading material supplier. The purpose, as also shown below, is to improve the color gamut by having a narrow FWHM and lower amount of color mixing The reason for this short blog entry however was not to highligh the progress with green perovskites. There are multiple firms reporting the same and now the key efforts are in improving light flux and thermal stability, driving down barrier requirements, and also setting up a large-scale production chain including film coating. The reason was however to show the below chart. It is showing a red perovskite QDs within black matrix sample. This is interesting because red is famously unstable to the point that few even dare publish results. Now, Nanolumi showed the results below in May 2020 but as far as I know they did not publish the stability data which is king. However, they must have felt confident enough to showcase it? well, they will be speaking at our event on 14-15 April so you can grill them (www.TechBlick.com)
