摘要：

目的无线供能系统的接收装置囿于尺寸限制难以满足越来越高的能量要求，提高空间利用率是解决这一难题的关键。方法从接收装置的姿态稳定性和体内温升安全性角度出发，通过实验方法确定接收装置磁芯的较优形状，并在给定尺寸约束下根据几何关系建立方程解出磁芯尺寸与导线股数和匝数，从而实现接收装置的结构优化。应用该方法对肠道机器人无线供能模块的能量接收装置进行了设计和实验。结果在外形≤10mm×10mm的约束下，接收装置输出功率可以保证在500mW以上，并且符合温升安全性要求。结论实验结果表明了这种带约束的对称性设计方法的有效性。

Objective Constrained by the limited sizes，the receiving set of the wireless power transmission system was hard to supply the increasing energy. The key of this problem is to improve the space utilization rate. Methods This paper focused on the orientation stability of the receiving set and its temperature rise inside the human body. The optimal sharp of the magnetic core was determined by experiments. An equation，whose solutions were the size of the core and the turns of the wire，was built according to the geometrical relationship. Then the optimal parameters of the receiving set were acquired and the receiving set of the intestinal robot was designed. Results In the size constraints of ≤10mm×10mm，more than 500mW could be provided by the receiving set and satisfied the temperature rise demand. Conclusions The symmetrical design method with size constraints was verified its effectiveness in the experiment.
