| Abstract: | Power shortage is the bottleneck for the implantable radio-telemetry system for animal physio- logical parameters to work stably for a long time. Wireless power transmission based on electromagnetic induction is an effective way to deal with this problem. In order to supply enough power to the radio-te- lemetry system safely and stably, the power transmission module was optimally designed considering the stability and electromagnetic biology safety during power transmission. The wireless power transmission module composed of transmitting coil of rectangle section solenoid and three-dimensional receiving coil was proposed. The module can provide at least 150 mW power to the load in a volume of Ф10. 5 mm×11 mm, that is, more than 2.64% of power transmission efficiency. Vivi experiments also verified the feasi- bility of this design. |
