Method and apparatus for conversion of movement to electrical energy

Abstract

A method for converting useful movement into electrical energy includes moving a structure against a surface thereby generating a force against a material integrated into the structure, deforming the material in response to the force to thereby generate electrical energy from the material, and harvesting the electrical energy. An apparatus for converting useful movement into electrical energy includes a smart material adapted to produce electrical energy when a force against the smart material is applied, and a plurality of coils in contact with the smart material for harvesting the electrical energy.

Description

PRIORITY STATEMENT [0001] This application is a Continuation-in-part of and claims priority to U.S. patent application Ser. No. 10 / 736,352 filed Dec. 15, 2003, herein incorporated by reference in its entirety.BACKGROUND OF THE INVENTION [0002] The present invention relates to energy conversion. More specifically, although not exclusively, the present invention relates to a converting movement associated with a structure, such as a tire or boot, into electrical energy. The electrical energy can then be stored or otherwise used. [0003] Although not the only application to the present invention, one aspect of the invention relates to problems associated with electric powered cars. Different approaches to the problem have been attempted, but significant problems remain, including lack of suitable light for solar cars, lack of cost effectiveness, and lack of efficiency. [0004] Another problem addressed by the present invention relates to the use of piezoelectric sensors. Although piezoel...

AI Technical Summary

Benefits of technology

This approach enables efficient and cost-effective conversion of mechanical movement into electrical energy, with the potential for high voltage generation, suitable for various applications including electric vehicles and footwear, offering a more direct energy response than piezoelectric sensors.

Problems solved by technology

Different approaches to the problem have been attempted, but significant problems remain, including lack of suitable light for solar cars, lack of cost effectiveness, and lack of efficiency.

Although piezoelectric sensors have been used in various applications to convert strain into a voltage, there are difficulties in using piezoelectrics in producing electrical energy.
