<P>PROBLEM TO BE SOLVED: To provide a technology which continually generates power even when an electronic apparatus is not vibrated, extracts a large amount of electric power, and is suitable for the size reduction in a technology which generates electric power through vibrations. <P>SOLUTION: An electronic apparatus 1 includes a power generator 10, a power supply part (secondary battery) 20 storing electric power generated by the power generator 10, and a processing part (load circuit) 30 driven by the electric power supplied by the power supply part 20. The power generator 10 includes a spring part 12, a power generation part 14 formed by a magnetostriction material, and a capacitor 16. The spring part 12 stores power by vibrations, operations by an operator, or wind force. The power generation part 14 generates power by the force stored in the spring part 12 when force is not applied to the magnetostriction material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
