摘　　要：针对植入式心脏起搏器电池供能时间有限的缺点和电磁感应无线供能在实际应用上的不足,提出了谐振式无线能量传输技术,介绍了植入式心脏起搏器谐振式无线能量传输系统的工作原理,基于磁耦合谐振原理和电路互感计算模型,建立了植入式心脏起搏器的谐振式无线能量传输系统数学模型,引入了空心线圈互感计算的精确公式,分析了轴向距离、径向偏移和线圈半径对系统传输性能的影响,这些结果对于合理设计心脏起搏器的无线能量耦合参数和优化系统传输性能提供了重要理论指导和参考。Aiming at disadvantages of the battery limited supply time of the implantable cardiac pacemaker and the actual application of electromagnetic induction wireless power transmission （WPT） system, the resonant WPT technology was proposed. The basic working principle of a WPT system of the implantable cardiac pacemaker was introduced. Based on Magnetic resonance coupling and mutual inductance calculation model, the mathematics models of the WPT system of the cardiac pacemaker were established. By the accurate formulae of the mutual inductance of the primary and secondary coreless coils, the influences of the parameters, such as the axial distance, radial offset and coli radius, on the VCPT performances were studied. And these results could provide an important theoretical guidance and reference for the design of the cardiac pacemakers coupling parameters and optimizing of the system performance.
