INTRODUCTION
MEMS (micro-electro-mechanical systems) are used in a wide range of fields, including transport, defense and telecommunications, and can be used to perform sensor and actuator functions on small surfaces. To do this, MEMS needs a source of energy. Until now, this function has been provided by batteries, whose main drawback is their limited lifespan. One solution is to recover energy from the microsystem's immediate environment. Here, we focus on the recovery of vibratory energy by electrostatic systems, and present the principles of conversion and the state of the art.
MEMS (Micro-Electro-Mechanical Systems) are present in many fields such as transportation, defense and telecommunications... and can, with small dimensions, perform functions of sensors and actuators. To do so, MEMS require a source of energy. So far, this function is provided by batteries whose main fault is the limited lifetime. One solution is to harvest energy in the immediate vicinity of the microsystem. Here we focus on the harvesting of vibrational energy by electrostatic systems, and present the principles of conversion and a state of the art.
