To provide a tire assembly including a power generating body with a simple structure.SOLUTION: A power generating body 22 comprises a first insulator film 211, a second insulator film 221, a first electrode 212 and a second electrode 222. The first insulator film has a first surface 210. The second insulator film has a second surface 220 facing the first surface and contacting the first surface. The first electrode has electrical conductivity, and contacts the rear face of the first surface of the first insulator film. The second electrode has electrical conductivity and contacts the rear face of the second surface of the second insulator film. The power generating body is so configured that an actual contact area of the first surface and the second surface is changed due to the deformation of a tire. The first insulator film and the second insulator film are so configured that one of them is electrified to be positive and the other is electrified to be negative due to the change of the actual contact area. Due to the electrification of the first insulator film and the second insulator film, voltage is generated between the first electrode and the second electrode to output electric power.SELECTED DRAWING: Figure 5
【課題】簡易な構造の発電体を備えるタイヤ組立体を提供する。【解決手段】発電体22は、第1絶縁膜211と、第2絶縁膜221と、第1電極212と、第2電極222とを備える。第1絶縁膜は第1面210を有する。第2絶縁膜は、前記第1面に対向し、かつ前記第1面に接する第2面220を有する。第1電極は、導電性を有し、前記第1絶縁膜の前記第1面の裏面に接する。第2電極は、導電性を有し、前記第2絶縁膜の前記第2面の裏面に接する。前記発電体は、前記タイヤの変形により、前記第1面と前記第2面との真実接触面積が変化するように構成される。前記第1絶縁膜と前記第2絶縁膜とは、前記真実接触面積が変化することにより一方が正に帯電し、他方が負に帯電するように構成される。前記第1絶縁膜と前記第2絶縁膜とが帯電することにより、前記第1電極と前記第2電極との間に電圧が生じ、電力を出力する。【選択図】図5
