植入式传感器系统中无线电能发射线圈的研究

为提高磁共振式无线电能传输系统的工作效率, 提出研究磁通量接收线圈强度的方法。以发射线圈为研究对象, 通过一种形函数对圆形、 矩形线圈进行仿真计算和深入研究。在实际效果区别较大的线圈形状中, 找出最优的线圈设计方法, 使其可在植入式传感器领域更好地应用。研究结果表明, 选取矩形发射线圈可同时在4个内角为4个接收装置供能, 从而大大提高传输效率。

Research on Wireless Energy Transfer Platform for Implantable Devices

To improve the efficiency of the energy transmission system,a method that can obtain the density gone through the receiving coil,will mainly used in study on the magnetic field that created by the transmitting coil,and stimulate the field with a sort of shape function is proposed.Because of using rectangle and circle as the transmitting coil differentiate the effect of transmission efficiency,we need to find out the optimal shape of the transmitting coil.The results say that rectangular transmitting coil can provide energy for four devices simultaneous,and more effective than circle coil.
