More Information
Summary:The invention provides a vibration power generation device having power generation ability that can be enhanced and a stable power generation characteristic, an energy conversion member constituting the vibration power generation device, a force sensor device having the energy conversion member, and an actuator. In a solution, the energy conversion member (1) is formed by joining a solid soft magnetic material (2) and a solid magnetostrictive material (3). The vibration power generation device (10) is configured to generate power by the inverse magnetostrictive effect of the magnetostrictive material (3), which is caused by the vibration of a vibration portion (13) comprising the energy conversion member (1). A force sensor device has a force detection portion for detecting a magnetizationchange caused by the inverse magnetostrictive effect of the magnetostrictive material when a sensor portion comprising the energy conversion member (1) is deformed and obtaining force acting on the sensor portion from the ma
