A liquid metal-based triboelectric nanogenerator as stretchable electronics for safeguarding and self-powered mechanosensing

A stretchable triboelectric nanogenerator was prepared by assembling shear stiffening polymer/polydimethylsiloxane with GaInSn. It shows outstanding energy-harvesting properties under large tensile elongation. As a self-powered sensor, it enables to monitor physiological motions. Besides, the TENG device can impede external collision by decreasing most impact energy which works as a protection material for human beings.182
