BACKGROUND
The wireless power transfer system (WPTS) is a promising way to continuously provide efficient and stable power for gastrointestinal capsule robots with active movement ability.
METHODS
The proposed WPTS using an optimised planar square spiral transmitting coil pair with space-saving structure can flexibly adjust the distance between the coils according to the patient's condition, and thus has better applicability. To improve power transfer efficiency and uniformity of the generated magnetic field, design parameters are discussed and optimised based on the analytical calculation and simulation analysis.
RESULTS
The power demand can be guaranteed with spacing distance of 350-500 mm and the peak received power of 1124 mW with a remarkable transfer efficiency of 7.8% can be obtained when the spacing reaches the minimum. The human electromagnetic exposure safety in different situations is also discussed and verified.
CONCLUSIONS
The WPTS can provide power for capsule robots safely and efficiently.
背景
无线电能传输系统（WPTS）是为具有主动运动能力的胃肠道胶囊机器人持续提供高效、稳定电能的一种很有前途的方法。
方法
所提出的 WPTS 使用优化的平面方螺旋发射线圈对，具有节省空间的结构，可根据患者的情况灵活调整线圈之间的距离，因此具有更好的适用性。为了提高功率传输效率和生成磁场的均匀性，基于解析计算和仿真分析讨论和优化了设计参数。
结果
在间距为 350-500mm 时，可以保证功率需求，当间距达到最小时，可获得高达 1124mW 的峰值接收功率和显著的 7.8%传输效率。还讨论和验证了不同情况下的人体电磁暴露安全性。
结论
WPTS 可以安全有效地为胶囊机器人供电。
