TL;DR: In this article, a dispositif de conversion reversible d'energie electrique a decoupage entre a source de tension alternative (2) and a source of courant alternatif (4) is defined.

TL;DR: In this article, the authors compared the performances of a vibrationpowered electrical generators using PZT piezoelectric ceramic associated to two different power conditioning circuits and showed that the nonlinear processing technique may increase the power harvested by a factor up to 4 compared to the standard optimization technique.

TL;DR: In this paper, the interrupter has a power converter, which is composed of semiconductor components e.g. thyristor and capacitors for storing electric energy, and a circuit detects the maximum or minimum of potential difference and controls the opened or closed state.

TL;DR: In this paper, the reliability and durability of a bimorph piezoelectric cantilever with a seismic mass at its tip is investigated. And the authors propose a new accelerated methodology and an associated test bench where the environment and stimuli can be precisely controlled over a wide period of time, which will allow the identification of potential failure modes and the study of their impacts by the way of direct mechanical investigation.

TL;DR: In this paper , the authors applied the electromechanical Ericsson cycles on several key materials and quantified the ultimate energy conversion capability of various ferroelectric ceramics and single crystals.
