Abstract

Piezoelectrochemical (PEC) materials use the coupling of mechanical and electrochemical energy to harvest low-frequency mechanical energy, which is possible even in systems such as commercial lithium-ion pouch cells. However, as it is relatively recently discovered in the literature, there has yet to be significant standardization for comparing the efficacy of different PEC harvesters. This article seeks to rectify this problem and proposes several metrics to consistently compare these harvesters, in hopes that using these metrics will enable the design of better-quality harvesters.
