Description
Technical Field
The invention relates to a wireless power transmission system of an intracorporeal implanted device.
Background
The in vivo implanted devices play an important role in medical monitoring, drug delivery, local organ stimulation, and the like. The battery life depends on the frequency and intensity of the device, and the battery must be replaced when the electricity reaches the use threshold. Battery replacement surgery, in addition to adding additional cost, more importantly increases the risk of surgical infection to the patient. Wireless power transfer can avoid economic and health problems associated with the replacement of the battery of the implanted device. The problem to be solved urgently is to improve the wireless power transmission efficiency of the implanted device.
The patent "201210366827.5 small size resonator and magnetically coupled resonant wireless energy transfer" discloses an implantable small size resonator for wireless power transfer. When the energy transmission distance is greater than the size of the receiving device and the transmitting device, the system energy transmission efficiency is seriously degraded. In order to increase the transmission efficiency, various measures are available. The 201280038109.3 patent "wireless energy transfer for implantable devices" discloses a wireless energy transfer system for an implanted device. The source resonator is arranged outside the body and generates an oscillating magnetic field. The implanted device resonator is placed in the body and captures the magnetic field generated by the source resonator. A relay resonator is added between a source resonator and an implanted device resonator, so that energy transmission is improved, and efficiency is improved. Patent CN201610807943 "metamaterial-based implantable wireless energy transmission device" discloses an implantable wireless energy transmission device based on a metamaterial, and a metamaterial relay module with negative magnetic conductivity is added to converge a spatial magnetic field, so that transmission efficiency is improved. However, parameters are not adjustable after the metamaterial design processing is finished. A small receiving coil wireless power transmission system such as a human body implant device puts higher requirements on universality and flexibility of the electromagnetic super surface. Due to individual difference of human bodies, the dynamic property of the human bodies and the uncertainty of the attenuation of electromagnetic fields passing through the multilayer tissues, the optimal working frequency of the system is changed. Once the metamaterial with fixed parameters is designed and processed, the parameters are not adjustable, and the dynamic response to the change of system parameters is difficult to make, so that the universality and the regulation and control flexibility of the metamaterial are limited.
