Electrostimulation by respiration‐driven TENGs. A, Schematic of a TENG‐driven electrostimulation device for wound recovery. Insets are a digital image of device (left bottom) and a rat wearing the device (right top), respectively. B, Wound‐healing mechanism under endogenous electric field. C, Digital images of the healing process with and without the TENG electric filed. D, Wound area as a function of time with (Experiment) and without the TENG electric filed (Control).
