HYBRID ELECTRIC ENERGY HARVESTER FOR GENERATING ELECTRIC ENERGY BY MAGNETIC FIELD VARIATION AND CONTACT

摘要

A hybrid electric energy harvester is disclosed. The hybrid electric energy harvester has electrodes; A coil-containing first contact charging layer disposed on the electrode; And a second contact charging layer which is disposed on the first contact charging layer and is capable of repeating contact and non-contact with the first contact charging layer and charged oppositely to the first contact charging layer, When the distance between the first contact charging layer and the second contact charging layer is changed, electric energy is generated in accordance with a change in the magnetic field, and the first contact charging layer and the second contact charging layer repeatedly contact and noncontact with each other Electric energy is generated by contact.
