ABSTRACT

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.

CONCLUSIONS

In summary, a novel stretchable, transparent and wearable body gesture and motion sensor has been developed. AgNWs are deposited on the PDMS layer with the help of pre-stretching strategy, oxygen plasma treatment and spin-coating process. The relative resistance (R/R0) response of the sensor to strain is approximately linear, which makes it suitable to be a strain sensor. The resistance of the sensor remains almost constant even after 1000 cycles of repeated stretching to 50% elongation and relaxing. When attached on the human skin or prosthesis, the sensor can monitor not only static gestures by resistance response to strain, but also dynamic motions based on triboelectrification and electrostatic induction at the same time. Then the gestures and motions could be restructured according to the results output above in real time. All of the excellent properties makes the sensor have much potentials in the development of multifunctional smart skins and wearable devices.
