Capsule-type electret generator and energy supply device

Abstract

The invention discloses a capsule-type electret generator and a power supply device. The capsule-type electret generator comprises a capsule-type closed structure and an electret vibrator, wherein thecapsule-type closed structure comprises an insulating shell, and electrodes arranged on the two sides of the insulating shell or a single electrode and an insulating part which are arranged on the two sides of the insulating shell respectively, and the capsule-type closed structure has an inner space; the electret vibrator is located in the inner space of the capsule-type closed structure and canmove between the electrodes or between the single electrode and the insulating part. The capsule-type electret generator is a single-electrode or double-electrode generator; compared with a traditional electret generator, the capsule-type electret generator can effectively reduce the loss of electric charges in an electret and prolong the service life of the electret; besides, the capsule-type electret generator is wide in working temperature range and environmental adaptation range, does not need repeated charging and is a clean power supply device; the energy source is wide, which is conductive to promotion, and thus the capsule-type electret generator has great application potential and commercial value.
