Implanting type integrated magnetic coupling resonator wireless energy transfer method

Abstract

The invention discloses an implanting type integrated magnetic coupling resonator wireless energy transfer method. According to the implanting type integrated magnetic coupling resonator wireless energy transfer method, four coils are utilized for transferring energy, wherein two coils are arranged outside a human body, the other two coils are arranged inside the human body, the two coils outside the human body are realized through a printed circuit board (PCB) and are respectively an energy excitation coil and an energy transmitter coil, and the energy transmitter coil is connected with a driving voltage source. The two coils inside the human body are realized through an integrated circuit and are respectively an energy receiver coil and an energy recovery coil, wherein the energy recovery coil, a rectifying circuit realized by the integrated circuit inside the human body, and other functional circuits are integrated on a single chip. A capacitor is connected in parallel on each of four coil return circuits, and therefore the four coils are enabled to have the same resonance frequency. According to the implanting type integrated magnetic coupling resonator wireless energy transfer method, the two coils inside the human body are realized through the integrated circuit and can be integrated on the single chip with the rectifying circuit and the other functional circuits, and therefore an implanting type integrated magnetic coupling resonator occupies a smaller space and is suitable for being used in implanting type medical electronic devices, wherein the space requirements of the implanting type medical electronic devices are harsh.
