An emerging class of two-dimensional (2-D) materials group, crystalline 2-D transition metal carbides or nitrides (MXene), has attracted considerable interest in the past decade. Murata has focused on an electrically conductive MXenes, especially for Ti3C2Tx in spray-coated film state (18000 S/cm at 5 um thickness). The hydrophilic nanosheet with outstanding properties (conductivity, high surface area and versatile surface chemistry) is a promising candidate of materials for flexible electronics using an eco-friendly manufacturing process. Swelling behavior of MXene by moisture is a roadblock for its applications in electronics. The interlayer spacing of layered structure is increased as stored in 60C/85% RH, which causes the degradation in electrical properties and the following oxidative reaction to TiO2. Murata has developed the concept of guest accommodation via hydrogen bonding to block water diffusion and demonstrated that it improves environmental stability in humid conditions. On 2 Dec, at TechBlick event on Printed Electronics Innovatipons, Shun Sakaida from Murata will present the latest developments in producing conductive Ti3C2Tx in spray-coated film state as well as in managing the moisture-induced swelling challenge. This is a step forward towrads allowing industrial use of this material in coated and/or printed applicaitons. his is an open free-to-attend event bringing together 25 presenters over two parallel live tracks, 30+ live virtual exhibitors and 400+ ...

Current printing technologies are based on wet printing methods such as inkjet and aerosol jet printers that suffer from complex and expensive ink formulation, limited printing material options, contaminations, low shelf life, and costly post-processing. Slide one shows a typical process. At TechBlick's free-to-attend online event on Printed Electronics Innovations on 2-Dec-2022 (https://www.techblick.com/PE-innovation-day), NanoPrintek present the world’s first “dry multimaterial printer”. This novel technology can transofrm printing from a traditional liquid-based to dry printing technology. This printer is schematically demonstrated in slide 2, showing how nanaoparticles are in-situ generated from a solid target to form a jet of nanoparticles which digitally prints onto the end substrates without ever requiring an ink. Slide 3 shows examples of devices printed using this technique on flexible substrates including paper. In this examples, copper and silver as well as materials such as Al2O3, BTO, SnO2, and TiO2 are dry printed! The Key technology advantages include 1) on-demand and in-situ generation of various pure nanoparticles without contaminations, 2) in-situ and real-time laser sintering of nanoparticles on various substrates with no further post-processing, 3) multimaterial printing of hybrid and composite materials and structures. The liquid-free nature of the system, the tunable flow dynamic of the nanoparticles, and the real-time sintering mechanism make it uniq...

Why are graphene tattoos the superior wearable interfaces?Why are graphene tattoos the superior wearable interfaces? What is it that you can do with graphene tattoos but not with other wearable systems? The answer is cuffless capturing of Blood Pressure! First, let's look into blood pressure (BP). BP is a vital representative sign of your health. If you have any problem with the cardiovascular system, BP will show it. But! To really catch the problem early, you need to measure BP continuously. Can it be done? Well, the modern technology of monitoring the BP is archaic and based on 100 years old sphygmomanometers. At the free-to-attend TechBlick conference on Wearable Electronics (www.TechBlick.com/wearables), Dmitry Kireev and Deji Akinwande from The University of Texas at Austin and Kaan Sel and Roozbeh Jafari from Texas A&M University will report on a unique technology capable of cuffless monitoring of Blood Pressure. The measurements are performed electrically, using Bioimpedance modality (Bio-Z), and graphene tattoos play the essential role as imperceptible and self-adhesive biointerfaces. The Bio-Z is performed dynamically with >10kHz sampling rate. A change in arterial volume (blood inflow) will affect the measured Bio-Z value. To capture the arterial Bio-Z, the graphene tattoos are placed on the skin right over the arteries (we got two on each wrist). Here four Bio-Z channels are simultaneously measured. Although the Bio-Z waveform is representative of BP, there is n...

Hybrid flexible systems combine printed electronics with the high power computing of established silicon electronics. To keep systems truly flexible, ultra thin chips are utilized. The slide below shows an example of preparing ultrachip dies from wafer singulation to creating thin dies. These dies are then placed upon flexible substrates with printed metallization and other printed components, creating hybrid flexible systems. A key challenge here is bonding, in particular achieving ultra fine pitch bonding, so that a wider range of ICs - complex ICs with high I/Os - are compatible and so that electronic designers can choose from a familiar repertoire of components to create products Slide 2 shows various chip integration approaches for flexible hybrid electronics. Broadly speaking, one can divide this into chip-first and chip-last approaches. In the chip first approach with flip chip bonding, traditional bonding techniques like solder, interposers, ACA/ACF, ICA, NCA, are utilized. In chip-last chip-on-flex techniques, printed interconnects are used. This is a hot area of development to enable complex next-gen flexible hybrid systems combining best-in-class chips with printed circuits On 2 Dec, at TechBlick event on Printed Electronics Innovatipons, Ali Roshanghias from Silicon Austria GmbH will present the latest developments towards ultra fine pitch chip bonding. This is an open free-to-attend event bringing together 25 presenters over two parallel live tracks, 30+ liv...

Tampere University researchers have developed a wearable highly unobtrusive low-cost e-tatoo enabling measurements of arterial pulse waves based on peizoelectric technology. This technology will be presented at the TechBlick conference on wearable sensors, e-textiles and printed electronics on 2 DEC 2022. This is a free-to-attend event online where you can network with 400+ attendees and visit 40+ booths. If interested please see agenda and register here www.TechBlick.com/wearables Slide 1: Cardiovascular diseases (CVDs) are the most common cause of death in the world accounting for approximately 30 % (~17.9 million) of all deaths in 2016. Extrapolating from this, the size of the risk group in danger of developing potentially lethal CVDs is counted in hundreds of millions worldwide (US alone was estimated to have 82.6 million people with CVD in a 2010 study). Continuous arterial pulse wave (pw) monitoring has been recently suggested to monitor this immense risk group. However, at the moment there exists no solution that would combine the cost-effective fabrication, unobtrusiveness and accuracy of these devices. Slide 2: In our study, we developed a scalable and cost-effective printing-based fabrication method for an electronic tattoo (e-tattoo) type pw-sensor and investigated its accuracy in-depth using a reference device and multiple study subjects. The device is based on bar coated P(VDF-TrFE) piezoelectric layer sandwiched between inkjet-printed GOPS cross-linked PEDOT:P...

Since advanced driver-assistance systems (ADAS) hit the auto market, reliable LiDAR and RADAR systems are crucial in the development of advanced self-driving vehicles. A significant challenge is to guarantee clear visibility even in the harshest environmental conditions. ATT advanced thermal technologies GmbH will present an excellent solution based on screen printing at TechBlick's event Free-to-Attend event on 2-DEC 2022. See agenda and sign up free here: https://www.techblick.com/PE-innovation-day To ensure visibility during winter, the RADAR & LiDAR sensor covers are currently equipped with wire based heating solutions. This state of the art solution comes with some technological challenges during the manufacturing process, causing significant scrap rates. The homogeneity of the sensor cover temperature is often inadequate and overheating or even burning issues have been detected. Since the required cooling air inlet of electrified vehicles is significantly smaller than that of a ICE car, large covers are used in the vehicle’s frontend to mimic characteristic air inlet designs by incorporating a decorative, opaque foil into the otherwise transparent cover. These grills house all types of sensors and cameras and thus, need to be heated to ensure a clear view of those devices, so a wire based heating system is added in addition to the decorative film. ATT advanced thermal technologies GmbH offers two alternative variants, both screen printed onto (transparent) polycarbonate...
