| 摘 要： | 针对消化道内微小系统,提出一种基于电磁耦合的无线能量传输方案.通过计算线圈间的互感,分析了相对位置对耦合系数的影响.建立了能量传输模型,推导出弱耦合情况下接收功率最大化的条件,指出提高传输效率的两种方法.实验传输功率超过200 mW(接收线圈位于发射线圈中心),验证了这种方案的可行性.

| Abstract: | A wireless power transmission method based on electromagnetic coupling was proposed for gastrointestinal microsystems.We analyzed the coupling coefficient,taking coils' misalignments into account by calculating mutual inductance.A power transmission model was built up.And based on this model,the electric parameters of maximizing the received power were deducted under weakly coupling condition.From the transmitting efficiency formula,we found two ways to enhance the efficiency.The transmission power was more than 200mW in our experiments when the receiving coil was located at the center of transmitting coil.This validated the method feasibility. |
