A method and device for generating electrical energy from the rotation of a wheel of a vehicle is disclosed. The device is disposed within a pneumatic tire and includes a coil housing having an interior chamber with a coil disposed thereabout, which is aligned for receiving a magnet within the chamber. The magnet is mounted within a magnet housing which has a first end aligned for reception in the groove of the coil housing, and a second end in communication with the interior wall of a tire. As the tire rotates, the tire deflection causes relative motion between the magnet and the coil generating electricity.

[ I claim:] [1.]1. An electrical power generating device for generating electricity from a deflection of a tire, the device comprising:a coil housing having a first end for mounting to a hub of a wheel, and an interior chamber with a electrically conductive coil disposed about said chamber;a magnet housing having a first end for mating engagement with said coil housing and a second end for engagement with an interior wall of said tire;said magnet housing further comprising a magnet assembly aligned for reception within the interior chamber of the coil housing so that the deflection of the tire directs the magnet housing radially inward so that the magnet assembly moves relative to the coils disposed within the chamber resulting in electricity being generated.
