TL;DR: A theoretical model of a piezoelectric based energy harvesting system that is simple to apply yet provides an accurate prediction of the power generated around a single mode of vibration is described.

TL;DR: This review presents an overview of the recent developments in new intrinsically stretchable piezoelectric materials and rigid inorganic pieZoelectrics materials with novel stretchable structures for flexible and stretchable PiezoeLECTric sensors and energy harvesters.

TL;DR: In this paper, the authors developed a new definition for the efficiency of an energy harvesting system, which instead of being defined through energy conservation as the ratio of the energy fed into the system to maintain the steady state to the output power, they considered the ratio that the strain energy over each cycle to the power output.

TL;DR: In this paper, a piezoelectric-based energy harvesting scheme is proposed, where a capacitor before the load in the conditioning circuit is used to expand the bandwidth of the system.

TL;DR: In this article, an analysis of the maximum power output of piezoelectric energy harvesters is presented, and the power limit and the optimal generalized electrical load or impedance to reach this power limit are first obtained directly by using the electromechanically coupled equations of the system, and then obtained by using equivalent circuit analysis and impedance matching approach.
