Fig. 5: Wireless signal transmission for sensing application with TENG as the sensor.

a System schematic of the wireless force sensor based on TENG. b, c are the received voltage signals with a coil distance of 0.35 m and 2 m, respectively. d The summary of the peak-to-peak voltage of the received signals as a function of coil distance. e The FFT spectrum of the received voltage signal under various contact forces. f The received peak-to-peak voltage and resonant frequency as a function of contact force with a 2 m coil distance. The inner and outer diameters of the coils are 21.5 cm and 27 cm, respectively.
