What is it about?
A self-powered sensor is fabricated by the combination of electronspinning nanofiber membrane and screen-printed Ag nanoparticles ink. Based on triboelectric effect, the breathable sensor can be used as breath monitor, finger motion detector, foot detector and so forth. Given features like air-permeability, massive fabrication and high sensitivity, the self-powered sensor holds great potential in wearable devices.

Why is it important?
Traditional wearable electronics are air-tight duo to the planer plastics they adopted, which will lead to inflammation after long time wearing. Moreover, the fabrication processes of electrode are always costly and the screen-printing technology we adopted here is cost-effective. The nanostructure constructed by the nanofiber and Ag nanoparticles promise the high sensitivity of the device as well.
Perspectives
Air-permeability is an important factor of wearable device as it bring more comfort for human skin. Nanofiber membrane is breathable, soft, skin-friendly and sensitive, which is a promising candidate for the fabrication of wearable devices.
