Abstract
The present disclosure discloses a power management circuit and a power management method for a triboelectric nanogenerator. The power management circuit includes a pulse current control switch, an intermediate energy storage element, and a target energy storage element, wherein the pulse current control switch is configured to instantaneously connect two electrode layers of the triboelectric nanogenerator to generate a transient pulse current, after movement of two relative moving components of the triboelectric nanogenerator generates static charges induced between the two electrode layers; the intermediate energy storage element is configured to store electric energy of the transient pulse current, and the target energy storage element is configured to store the electric energy output from the intermediate energy storage element.
