Figure 5. Application demonstration of the FL-TENG. (A) Charging voltage curves of different capacitors at 7 m/s. (B) The FL-TENG lit up the “GXU” logo. (C) Charging a 470 μF capacitor to drive five parallel-connected calculators at a wind speed of 5.5 m/s. (D) Charging a 4.7 mF capacitor to drive twenty-five parallel-connected hygrothermographs at a wind speed of 5.5 m/s. (E) Charging a 4.7 mF capacitor to drive a multimeter at a wind speed of 7.5 m/s. (F) Charging a 10 mF capacitor to drive a flame sensor at a wind speed of 7.5 m/s.
