In situ conversion of mechanical energy into electricity is a feasible solution to satisfy the increasing power demand Internet Things (IoTs). A triboelectric nanogenerator (TENG) considered as potential via building self-powered systems. Based on triboelectrification effect and electrostatic induction, conventional TENG with pulsed AC output characteristics always needs rectification storage units obtain constant DC drive electronic devices.
