摘要

Traditional methods of power supply for implanted medical device is extremely inconvenient. Witricity is a new technology for transmitting energy wirelessly via resonant coupling in the non-radiative near-field. Wireless power transmission based on coupled magnetic resonance provides an effective way for implantable medical devices of power supply. Principle of wireless power transmission based on coupled magnetic resonance for implantable medical devices is introduced,theoretical basis coupled mode theory( CMT)of wireless power is stated. Based on the theoretical simulation,necessary conditions of magnetic coupled resonant wireless power effective transmission is researched.%体内植入医疗装置已被广泛应用，然而使用传统的供电方法为其供电却极为不便。磁耦合谐振式无线电能传输通过近场区强耦合谐振实现能量的高效传输，为体内植入医疗装置的供电提供了有效途径。介绍了体内植入式医疗装置的磁耦合谐振式无线电能传输原理，阐述了无线电能传输技术的理论基础耦合模理论（ CMT），并基于该理论仿真研究了磁耦合谐振式无线电能传输技术高效传输的必要条件。
