Title:
TIRE WITH ELECTRIC-POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/085550
Kind Code:
A1
Abstract:
A tire with an electric-power generation device for supplying sufficient electric power by a simple and small-sized construction. An electric-power generation device (100) for converting strain occurring in a tire (1) into electric energy has at least one power generation element (10) and a device body (100a). The power generation element (10) is constituted of at least two stretchable electrodes (11) and of a dielectric elastomer (12) that is provided between the electrodes (11) and produces an electric potential difference between the electrodes (11) based on the strain applied from the tire (1). The device body (100a) has an accumulator for accumulating electric energy produced by the power generation element (10). The length, in the circumferential direction of the tire, of the power generation element (10) is set such that strain by contraction and strain by expansion that are caused by the rotating tire (1) coming in contact with the ground are not simultaneously applied to the single power generation element (10).
