Study of effects of CaCl2-CNF film parameters on the output stability of SOP-TENG. (a–c) Study of the effect of moisture content on the output voltage of the SOP-TENG. (a) Voltage waveform of SOP-TENG with nonmoisture content. (b) Voltage waveform of SOP-TENG with low moisture content. (c) Voltage waveform of SOP-TENG with high moisture content. (d) Study of the effect of continuous operation on the output voltage of the SOP-TENG. The voltage data gained through the oscilloscope only dropped by 3.5% after continuous operation of 10 000 cycles, conforming superstable output performance of the SOP-TENG. (e) Study of the effect of device aging on the voltage output performance of the SOP-TENG. The measured voltage and the current response of a SOP-TENG after 120 days were 226 V and 5.18 μA, respectively, which only declined by about 5% and 3.3% compared with the initial value.
