METHOD AND DEVICE FOR MECHANICAL ENERGY HARVESTING

摘要

An apparatus for harvesting electrical power from mechanical energy is described. The apparatus includes at least one magnetostrictive element, at least one electrically conductive coil or circuit, and a magnetic circuit coupled to the electrically conductive coil or circuit to increase or maximize power production. The magnetostrictive element is configured to experience a forced stress and strain in response to external mechanical excitations. The electrically conductive coil or circuit is configured to produce electrical energy through electromagnetic induction.
