Abstract
A power generating device including an element and a moving member. The element is deformable and generates power when deforming. The moving member moves when receiving a vibration, and contacts the element when moving. When the moving member contacts the element, the element deforms into another state or returns to a previous state.
Claims12
A power generating device comprising:
- an element being deformable, that generates power when deforming, and comprises a pair of electrodes, and
- an intermediate layer having elasticity, disposed between the electrodes in a thickness direction of the element;
- and
- a moving member that moves when receiving a vibration, configured to contact the element when moving,
- wherein, when the moving member contacts the element, the element deforms into another state or returns to a previous state,
- wherein the intermediate layer comprises at least one of a rubber and a rubber composition, and
- wherein the intermediate layer has a first side and a second side opposite the first side in the thickness direction of the element, and the first side has been subjected to a surface modification treatment and an inactivation treatment, which causes the first side and the second side to deform to different degrees of deformation when the same deformation imparting force is applied thereto and causes the first side to store charge.
