POWER GENERATOR

PROBLEM TO BE SOLVED: To provide a power generator capable of suppressing deterioration of an element even when a moving member repeatedly collides with the element, and maintaining an excellent power generation capability for a long time.SOLUTION: A power generator 1, formed in a sealed box shape, comprises: an element 2 which generates power by deforming itself; and a moving member 3 which is spherical and arranged inside the element 2 in a rotatable manner, and collides with the element 2, being moved by external vibration. The element 2 has a frame for determining the box shape, a second electrode arranged on an innermost face of the frame, an intermediate layer, a first electrode, and a cover member which is flexible, in this order. When the moving member 3 collides with any inner surface of the element 2, the cover member having flexibility is deformed, the first electrode, the intermediate layer, and the second electrode are deformed so as to absorb impact, and power is generated. When the moving member 3 moves to another place, the deformation returns to an original state.SELECTED DRAWING: Figure 1 【課題】移動部材の繰り返しの衝突による素子の劣化を抑制でき、長期に亘って良好な発電能力を維持できる発電装置を提供する。【解決手段】発電装置１は、密閉された箱形状をなし、変形して発電する素子２と、素子２内に転動可能に設けられ、外部から受ける振動により動いて素子２に衝突する球状の移動部材３とを有している。素子２は、箱形状を規定するフレームと、フレームの最内面に配置された第２の電極と、中間層と、第１の電極と、柔軟性を有するカバー部材とをこの順で有している。移動部材３が素子２の或る内面に衝突すると、柔軟性を有するカバー部材が変形するとともに、第１の電極、中間層及び第２の電極が変形して衝撃が吸収されるとともに、発電がなされる。移動部材３が他へ移動すると変形は元に戻る。【選択図】図１
