Schematic diagram and energy-harvesting performance. a Schematic diagram of the complete stack of stretchable and healable triboelectric nanogenerator (SH-TENG), where latex is used a the positive triboelectric layer, polyurethane acrylate (PUA) is used as the negative triboelectric layer and (polyurethane acrylate + silver flakes + liquid metal) is used as the current collector. The performance of the SH-TENG was evaluated when it was subjected to a mechanical force of 40 N at a frequency of 5 Hz. b Output voltage (Vop), c current density (Is), d charge-transfer density (σT), and e output voltage of the SH-TENG with PUA as the negative triboelectric material and different positive materials (latex, aluminum (Al), polyethylene terephthalate (PET), and PUA). f Variations in output voltage, current, and power density as functions of external impedance
