Abstract
The present disclosure relates to nanogenerator technology, and discloses a method and a circuit for energy management in a Triboelectric Nanogenerator (TENG), as well as an apparatus including the circuit. The method includes: storing electrical energy outputted from the TENG temporarily in a temporary energy storage; and transferring the electrical energy stored temporarily in the temporary energy storage to an energy storage. With the above solution, the temporary energy storage can be charged and discharged periodically, so as to charge the energy storage. It is possible to achieve impedance match between the TENG and the energy storage and thus a significantly improved energy storage efficiency, such that an AC outputted from the TENG can be converted into a constant-voltage DC output efficiently.
