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. Check out the agenda and register here www.TechBlick.com/wearables
Slide 1 shows the schematic of the device. Here, you can see the role of flexible printed electronics in enabling truely wearable electrodes (interfaces). Furthermore, you can also see the full electronic box, featuring miniaturized wireless electronics, data storage, cloud, automated data analysis, etc. This is a great example of developing a full read-to-deploy product.
slide 2 show an application example. Here, the device, powered by BT with 10 hours of operation- can be comfortably worn by the user. This picture demonstrate the elegance of the design based on possibilities of printed flexible electronics as well as low power BT-powered electronics.
Slide 3 shows examples of facial EMG showing how the signal pattern - caused by facial distortion - is different for each emotional expression. The final slide shows the signals in more details, demonstrating how this device can also be a tool in measuring and quantifiying the link between emotional states and physical facial expressions.
This is an exciting technology which will be presented on 2 Dec 2022 at TechBlick's free-to-attend wearable conference. Check out the agenda and register here www.TechBlick.com/wearables
