Title:
ELECTRIC POWER GENERATION DEVICE, TIRE ASSEMBLY, AND AUTONOMOUS ELECTRIC POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/037244
Kind Code:
A1
Abstract:
An electric power generation device is mounted to the inside of a tire and generates electric power using the mechanical energy of the tire. The electric power generation device is provided with: a first electrode structure (15) having a first electrode (11); a second electrode structure (16) having a second electrode (12); and an affixation section (17) for affixing the first electrode structure (15) and the second electrode structure (16) so that the distance at which the first electrode structure (15) and the second electrode structure (16) face each other is variable. The first electrode structure and/or the second electrode structure has a charge body (13, 14) for generating static electricity on the facing surface side. The first electrode structure is affixed to the tire, and the second electrode structure is adapted to be movable relative to the first electrode structure. The electrostatic charge body comes into contact with the facing electrode structure in response to the deformation of the tire to thereby generate static electricity. Also, when the distance at which the electrode structures face each other increases in response to the deformation of the tire, a difference in electrical potential occurs between the first electrode and the second electrode. Thus, the provided electric power generation device has an inexpensive and simple structure and high durability.
