<P>PROBLEM TO BE SOLVED: To provide a power generator in a tire capable of obtaining high power by efficiently generating power from a state of low speed rotation of a tire. <P>SOLUTION: The power generator in the tire is attached to a tread portion in a tire air chamber. The power generator in the tire includes a rotational body that is partially formed by a magnet so that a center of rotation differs from the center of gravity and that is rotated in accordance with a change in force applied to the tread portion during traveling of a vehicle, a coil unit that faces the rotational body and that generates power by generating a voltage by an electromagnetic induction action of magnetic flux emitted from the magnet, a power storage unit that stores the voltage, and a control unit that controls the power generated by the coil unit in response to the change in force applied to the tread portion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
