Stretchable, transparent and wearable sensor for multifunctional smart skins

This paper reports a novel active body motion sensor with PDMS-AgNWs structure, which is not only highly sensitive to detect body static gestures by strain-resistance response, but also self-powered to recognize both body and prosthesis motion based on triboelectrification and electrostatic induction synchronously for the first time. By attaching the sensor on human skin or robot surface directly, the motion of the relative surface could be reconstructed simultaneously. Particularly, the sensor could work as functional part of smart skins and wearable devices for its great stretchability and transparency.
