The Third Generation of Nanogenerators: The Irreplaceable Potential Source Enabled by the Flexoelectric Nanogenerator

Abstract

The electroneutrality assumption has long been adopted by scholars; however, this assumption may lead to an oversight of certain physical effects. Using derivations from a discontinuous medium, we have obtained an expression for the potential and energy of a many-body unipolar charge system, which corresponds well to its counterpart in a continuous medium. The compressed form of this expression suggests that compressing a macroscale charged body to the nanoscale can yield an enormous electric potential and energy, thereby establishing a concrete research framework for third-generation nanogenerators. This effect may serve as a crucial reference for understanding anomalous spatial electromagnetic distributions and divergent energy fields.
