ENERGY CONVERSION ELEMENT, VIBRATION GENERATOR, POWER SENSOR DEVICE AND DRIVE ELEMENT

摘要

The object of the invention is to provide a vibrating power generator with high power generation capacity and constant power-generating property, an energy conversion element, of which the vibrating power generator is part, a force sensor device comprising the energy converting element, and a drive element. Means for solving the problem is energy conversion element 1 made of a composite of solid soft magnetic material 2 and solid magnetostrictive material 3. Vibration current generator 10 is designed to generate electricity from energy conversion element 1 via the inverse magnetostriction effect of magnetostrictive material 3 when the vibration element 13 vibrates. The force sensor device comprises a force detector which, when the sensor unit is deformed from the energy conversion element 1, detects a change in magnetization due to the inverse magnetostriction effect of the magnetostrictive material, and from this concludes the force acting on the sensor unit. The drive element 20 is designed to set the vibration element 13 from the energy conversion element 1 in vibration via the magnetostriction effect of the magnetostrictive material 3.
