All-solid-state flexible self-charging power cell basing on piezo-electrolyte for harvesting/storing body-motion energy and powering wearable electronics

All-solid-state flexible self-charging power cell (SCPC) is fabricated using solid piezo-electrolyte. The solid piezo-electrolyte (mesoporous PVDF-LiPF6 film) can act as both the electrolyte and piezo-separator. The SCPC can be efficiently charged up by mechanical deformation, and thus can directly harvest/store the body-motion energy. The SCPC can power a variety of wearable electronic devices.192
