Problems solved by technology

The existing non-contact charging technology uses electromagnetic induction to transmit energy between the charger and the electrical equipment. Although there is no wire connection between the two, the transmission distance can only reach the millimeter level.
This distance is far from meeting people's needs

Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission, and in particular relates to an implantable medical equipment charging system based on magnetic coupling resonance wireless energy transmission technology. Background technique [0002] Since human beings entered the electrical age, the transmission of electric energy has always been carried out by wire. With the development of microelectronics technology, especially the development of implanted medical instruments, higher requirements are placed on the power supply methods of existing electronic equipment. Since the traditional power transmission methods are all using contact transmission, this power transmission method can no longer meet the needs of the development of electronic technology. Therefore, based on this problem, a technology that transmits electric energy in a non-electrical direct contact manner, that is, wireless power transfer technology (WPT), has emerged....
