  • Patent number: 9705429
    Abstract: A power generating element is provided. The power generating element includes a pair of electrodes and an intermediate layer disposed between the pair of electrodes. The intermediate layer includes an insulating elastic body. The power generating element is flexibly bendable when receiving an external force, while causing a sliding transfer between at least one of the electrodes and at least one surface of the intermediate layer which faces the at least one of the electrodes, due to a difference in curvature between the electrodes and the intermediate layer.

  • Publication number: 20170170749
    Abstract: A power generating device is provided. The power generating device includes 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.

  • Publication number: 20170149357
    Abstract: A power generating element is provided. The power generating element includes an electrode pair and an intermediate layer. The electrode pair includes a first electrode and a second electrode. The intermediate layer is disposed between the first electrode and the second electrode. The intermediate layer is insulating and has a first side facing the first electrode and a second side facing the second electrode. The first electrode and the intermediate layer together operate as a contact/separation mechanism configured to perform a contact/separation operation, when an external force is applied to the power generating element to generate power. In the contact/separation operation, the contact/separation mechanism transitions between a contact or close state in which the first electrode and the first side are brought into contact with each other or close to each other, and a separation state in which the first electrode and the first side are separated from each other.
