Study of the effect of the relative humidity on output stability of SOP-TENG/PET-based TENG. (a) The influence of relative humidity on the electrical performance of the PET-based TENG. As the relative humidity increased, the voltage and current output of the PET-based TENG decreased rapidly. (b) The effect of relative humidity on the electrical performance of the SOP-TENG. Before the relative humidity rose to 80%, it had a slight effect on the electrical output performance of SOP-TENG. (c, d) Showed the electrostatic charge distribution on the friction surfaces of PET and CaCl2-CNF film in the dry and humid environment, respectively.
