Abstract
An electronic device includes a power generator, a power supply unit (secondary battery) which stores power generated by the power generator, and a processing unit (load circuit) which is driven with power supplied from the power supply unit. The power generator includes a spring, a power-generating unit which is formed using a magnetostrictive material, and a capacitor. The spring stores force by vibration, operation of an operator, or wind power. The power-generating unit generates power by force stored in the spring when force is not applied to the magnetostrictive material.
