ELECTRICITY-GENERATING DEVICE

摘要

This electricity-generating device (100) contains a dielectric body (103) and an electret (104). The dielectric body (103) constitutes part of a movable mass (101), and the electret (104) holds an electric charge. This electricity-generating device (100), which generates electricity via changes in the distance between the dielectric body (103) and the electret (104), also contains electret-supporting members (a repulsing member (106a) and spring members (106b)) that elastically support the electret (104).
