Abstract
The main purpose of this invention is a system for conversion of mechanical energy into electrical energy by electrostatic conversion, comprising at least one fixed electrode (2) and at least one mobile electrode (4) that can be vibrated by mechanical energy, facing the fixed electrode, said fixed (2) and mobile (4) electrodes being separated at rest by an air gap distance (Δ), said system comprising means (12) of modifying the air gap distance as a function of the variation of the vibration amplitude of the mobile electrode (4).
Another purpose of this invention is an energy conversion method using such a system.
