An All-Elastomeric Transparent and Stretchable Temperature Sensor for Body-Attachable Wearable Electronics

A transparent stretchable (TS) gated sensor array with high optical transparency, conformality, and high stretchability of up to 70% is demonstrated. The TS‐gated sensor array has high responsivity to temperature changes in objects and human skin. This unprecedented TS‐gated sensor array, as well as the integrated platform of the TS‐gated sensor with a transparent and stretchable strain sensor, show great potential for application to wearable skin electronics for recognition of human activity.
