Fig. 2: The electric signals of an acoustic-driven TENG in air and water.
From: Underwater wireless communication via TENG-generated Maxwell’s displacement current
a Schematic diagram of the experimental process. ID represents displacement current in all figures. b Schematic diagram of the working principle. E is the underwater electric field, and v is the speed of the TENG for contact and separation. c The short-circuit current signals (measured by connecting an electrometer to the aluminum electrode). d The short-circuit current signal obtained by connecting the electrometer to the receiving electrode.
