(a) Capacitor charging of P3HT/PVDF-HFP nanofibers TENGs having various capacitances. (b) (I) Schematic representation of the operating circuit for LED bulbs with a full-wave bridge rectifier and (II) photograph of 500 serially connected LEDs and a digital watch powered by a TENG formed from P3HT/PVDF-HFP nanofiber mats (device size: 2.5 cm × 2.5 cm). (c) Sensitivity of the P3HT/PVDF-HFP nanofiber TENG, measured by varying the number of fingers pressing on the device.
