Contemporary electroencephalography (EEG) and surface electromyography (sEMG) are notoriously cumbersome. Using printed electronics, low-power electronics and data analysis tools the X-trodes system bring electrophysiology techniques to a new level: By eliminating the need to handle multiple electrodes, wires and amplification units electrophysiological monitoring can be achieved while maintaining electrode-skin stability, and user convenience during prolonged use (hours). The presentation will outline several important applications (focusing on sleep monitoring at home and facial muscles) and how each can benefit from the convergence of electrophysiology and novel skin electrophysiology. This technology will be presented at the TechBlick wearables conference on 2Dec2022. This is an online FREE-to-Attend conference.

Author: Marc Reuter | Panacol | marc.reuter@panacol.de When it comes to electronics, characteristics like bendability, flexibility, foldability and wearability become increasingly important. To produce functioning devices with those characteristics it is necessary that all device parts are flexible or bendable. Usually, the electronic parts, especially those mounted on PCBs or flexible PCBs, are connected by soldering. But solder materials are very rigid and inflexible. In addition, soldering temperatures of 600° to 700°F (316° - 371°C) are an increasing challenge for heat-sensitive modern electronic devices. Therefore, soldering to create conductive connections between the separate electronic parts is not an option for modern flexible electronic devices. Fig.: Bonding and creating an electrical connection in one step: Small chips are fixed to flexible tracks with a conductive connection. Conventional conductive adhesives were invented for this purpose, which already makes it possible to bond two electronic components on circuit boards without a major temperature stress. But these conventional adhesives must be applied on a hard surface, to create a high conductivity. For softer more flexible surfaces, like thin film solar cells, in-mold electronics or electronic wearables and flexible electronics in common, other ways of contacting need to be in place. For these applications a high flexibility of the whole device is often required. Epoxy-based flexible conductive adhesives a...

We highlight important advancements in MicroLED and/or QD displays in this article using technology slides. These advancements of the art will be presented at TechBlick’s 2-day global conference on “Mini- & Micro-LED Displays: Markets, Manufacturing Innovations, Applications, Promising Start-ups” taking place online in TechBlick’s ‘in-person virtual’ platform on 30 Nov - 1 Dec 2022. The agenda includes the likes of Samsung, Sharp, AUO, Coherent, ASMPT, Komori, CEA, Micledi, 3D Micromac, Allows Semiconductors, and many more. The full agenda can be seen here www.TechBlick.com/microLEDs What is the future market for microLEDs in terms of unit sales, application, chip type, and backplane? The slides below share some key forecasts and analyses by Jerry Kang from Omdia - one of the leading analysts in the field - who will present live online at TechBlick's microLED and QD event on 30Nov-1Dec www.TechBlick.com/microLEDs Slide 1 shows that the microLED market will experience substantial growth in the coming years. In 2021, the sales were expected to be just 0.12k units, reflecting the lack of technology maturity and the manufacturing high cost/low yield. In 2029, the figure is expected to reach 12.7M units per area. This is a transformational growth, and yet still represents just 0.3% of the total FPD market! Slide 1 also shows the split of the market - in thousands of units - by application. The first to arrive were public displays owing to low technical barriers and much larger die...

Stretchable microLED displays without distortion? There are three significant hurdles in the commercialization of stretchable displays. First, the stretching of display panels inevitably accompanies image distortion and non-uniform deformation. Second, the conventional display substrate suffers from low stretchability. Third, the stretchable rubber substrate is incompatible with today’s display fabrication process due to its significant thermal expansion and low dimensional stability.
Jae-Hyun Kim from KIMM (Korea Institute of Machinery & Materials) will present a solution at TechBlick's upcoming microLED event. Checkout the full agenda here www.TechBlick.com/microLEDs
This talk presents a stretchable meta-display enabled by micro-LEDs to overcome the limitations of conventional stretchable displays. As shown in slide one, an auxetic metamaterial with a Poisson’s ratio of -1 and electric interconnections was designed as a substrate of the stretchable display for stretching without image distortion and with uniform deformation. A highly stretchable circuit board was realized using a polyimide substrate, a conventional display substrate for commercialized OLED flexible displays. As shown in slide two, the auxetic metamaterial consists of kirigami-cutting lines made by the UV laser. The structural stretchability of kirigami overcomes the low material stretchability of polyimide and reaches a panel stretchability larger than 20%. The polyimide substrate has excellent dimensi...

Dr. Yeo's group at Georgia Tech University is doing pioneering work on soft materials, flexible mechanics, nanomanufacturing, machine learning, and system packaging to develop intelligent soft wearable biosensors and bioelectronics. These systems combine soft stretchable flexible substrates and materials with rigid electronics, creating soft yet powerful electronic systems. The diversity of the research programme is fascinating. In slide one, you can see a selection of ongoing projects in Dr. Yeo's research group regarding the study of soft materials and development of soft biosensors and bioelectronics In slide 2, you can see a picture showing the comparison between a soft electronic system on fingers and conventional rigid wearables on the wrist. This Is where the true advantage of soft electronic systems shines!
In slide 3 you can see examples of developed wearable bioelectronic systems. Here, one can see the combination of extreme stretchability, thinness, and rigid ICs and electronics. Dr. Yeo will present the latest developments at TechBlick's FREE-to-Attend event on 2-Dec. Check out the agenda and secure your place now www.TechBlick.com/wearables...

MicroLED displays have the triple-challenge of transferring millions of components that are vanishingly small with sub-micron precision. One way to achieve this is by using chemistry and the tools of microlithography, leveraging the processes used for nano-scale semiconductor fabrication. This apporach is developed by Terecircuits who will be presenting on 30 NOV - 1 DEC 2022 at TechBlick's MicroLED conference taking place live online. Here is the agenda www.TechBlick.com/microLEDs Slide 1 shows one optimization: A deep UV light source is used to expose an entire carrier holding an epi-wafer of MicroLEDs, released and singulated onto the carrier via Laser Lift Off (LLO) or a chemical process. At the same time, a mask is positioned to selectively release only the MicroLEDs at the pixel pitch. In this way tens of thousands of components can be transferred in a single operation, preserving the accuracy of the die-to-die relationships from the fabrication pitch. Masks can also be used to depopulate know bad die and perform defect repair on existing assemblies. The design of the material which holds the MicroLEDs on the donor carrier is critical. This material needs to both hold the MicroLEDs securely without drift prior to release, then when activated by the Laser-Induced Forward Transfer (LIFT) process, cleanly release and propel the dice towards the substrate without damage and with minimal or no residue. Slide 2 shows that Optimizing a Transfer Material to work with a mask (...
