Abstract

The invention discloses an in-vivo implanted device wireless power transmission system based on an electrorheological fluid metamaterial. The system comprises a transmitting module, a receiving module, an electrorheological fluid metamaterial module and a direct-current power supply, wherein wireless power transmission is carried out in a magnetic resonance coupling mode, And the electrorheological fluid meta-material module is composed of electrorheological fluid meta-material units, and can converge the magnetic field generated by the transmitting module so as to improve the wireless power transmission efficiency. According to the invention, the dielectric constant of the electrorheological fluid is changed by adjusting the intensity of the external electric field of the electrorheological fluid, so that the resonant frequency of the electrorheological fluid electromagnetic metamaterial and the equivalent permeability value at the working frequency of the system are changed, and theadvantage of flexible and adjustable parameters is achieved.

Description

technical field [0001] The invention relates to a wireless energy transmission system for implanting devices in the body. Background technique [0002] In vivo implantable devices play an important role in medical monitoring, drug delivery, local organ stimulation, etc. Battery life depends on the frequency and intensity of use of the device, and must be replaced when the charge reaches a usage threshold. In addition to the additional cost of battery replacement surgery, more importantly, it increases the risk of surgical infection for patients. Wireless power transfer could avoid the financial and health problems associated with battery replacement for implanted devices in the body. Improving the efficiency of wireless power transmission is an urgent problem to be solved for wireless power transmission of implanted devices in vivo. [0003] The patent "201210366827.5 Small-sized resonator and magnetic coupling resonance wireless energy transmission" discloses a small-siz...
