摘要：

This paper presents an optimized 3-coil inductive wireless power transfer system with wearable power transmitting coil (PTC), miniaturized power receiving coil (PRC), and power amplifier. The PTC is made wearable to improve system's compactness and portability. The PRC and its circuitry are sufficiently miniaturized so that they can be embedded in the tiny capsule replacing the conventional onboard battery. In addition, the power amplifier is specially designed and optimized to enable convenient line-tune for impedance matching. This minimizes unnecessary mismatch normally contributed by changes on impedance of the power transmitting coil because of the use of different size of PTC for different patient group, deformation of the PTC, etc. The experimental test shows our proposed system obtained the power transfer efficiency at least 7.53% when 708 mW of power is transferred.
