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.

Description

technical field [0001] The disclosure belongs to the field of new energy and ergonomics, and relates to a capsule electret generator and an energy supply device. Background technique [0002] At present, lithium battery power supply has become the mainstream energy supply method for portable mobile appliances. The dependence of traditional batteries on the charging environment has undoubtedly become a major limitation. In addition, discarded batteries will also bring harm to the environment. The pursuit of clean energy has always been the goal of researchers, and providing clean, high-power, and stable power supply devices is now a hot spot in energy demand. [0003] Electret is a dielectric with a wide range of uses for electricity storage. With the development of science and technology, it has gradually shown its potential as an important electronic material in the fields of environmental purification, energy, electronic engineering, and biomedicine. have important applic...
