Figure 5. Skin-interfaced energy harvesting system consisting of a fully soft bridge rectifier. (A) An optical image of the skin-interfaced energy harvesting system placed on a human hand; (B) Schematic exploded view of the skin-interfaced energy harvesting system; (C-E) Time-dependent output voltage of the PENG (C), the PENG integrated with a bridge rectifier (D), and the PENG integrated with the capacitor-equipped bridge rectifier by finger tapping (E). PENG: Piezoelectric nanogenerator; AC: alternating current.
