Theoretical study of enhancing the piezoelectric nanogenerator’s output power by optimizing the external force’s shape

The average power is one of the key parameters of piezoelectric nanogenerators (PENGs). In this paper, we demonstrate that the PENG’s output can be gigantically improved by choosing driving force with an appropriate shape. When the load resistance is 100 MΩ and the driven forces have a magnitude of...
