Nanoscale flexoelectric energy harvesting
TLDR
In this article, a beam-based paradigmatical design was proposed for flexoelectric energy harvesting under harmonic mechanical excitation. And the authors showed that the output power density and conversion efficiency increase significantly when the beam thickness reduces from micro-to nanoscale and flexolectricity-based energy harvesting can be a viable alternative to piezoelectrics.About:
