A power-transformed-and-managed triboelectric nanogenerator and its  applications in a self-powered wireless sensing node.
A power-transformed-and-managed triboelectric nanogenerator (PTM-TENG) is invented that is intended to give regulated power output for driving electronics. The design is based on a synchronized mechanical agitation that not only drives the TENG but also switches the connections for the capacitors for lowering the output voltage and increasing the output charges. An energy preservation efficiency of >95% was demonstrated. The PTM-TENG not only detected the external mechanical triggering action but also generated enough power for sending out an infrared signal.
