Abstract
A kind of electromagnet-friction Piezoelectric anisotropy formula energy collecting device is the utility model is related to, belongs to MEMS and micro- energy technology field.Place permanent magnet in collector enclosure interior both sides, rotating shaft is connected by bearing with housing, the cantilever beam of concave shaped design is connected in rotating shaft, cantilever beam both ends are respectively fixedly connected with hemispherical mass, the piezoelectric ceramics for being covered with cushion is installed on enclosure interior, coil is wound with cantilever beam, has the second frictional layer outside coil, corresponding position is followed successively by the first frictional layer between second frictional layer and housing, flexible piezoelectric material and insulation fill stratum, the energy of collection is exported by first electrode layer and the second electrode lay external circuit, first electrode layer connects flexible piezoelectric material and the first frictional layer, the second electrode lay is located at rotating shaft top, pass through wire connecting line circle and the second frictional layer.Advantage is that vibrational energy is converted into electric energy, to output energy supposition amplification, the further energy conversion efficiency for improving device.
