摘要
为使结肠机器人摆脱供电线缆,深入肠道内部,研制了一种无线供能装置.该装置基于电磁耦合原理,可在人体胃肠道区域产生固定频率的均匀交变磁场,并针对结肠机器人在人体内运动的功率要求、姿态与位置的不确定性及尺寸要求等,设计了合适的接收线圈模型.用不同股数的绕线制作了8种相同外形尺寸的接收线圈,比较各线圈的接收效率,最终选用10股绕线制成的线圈.实际搭建了为肠道机器人供能的无线能量传输系统,并验证了其可行性.
The wireless power supply equipment, based on electromagnetic induction, was designed to provide a wireless colon robot penetrating into the intestinal canal, which generates an alternating magnet- ic field covering the whole gastrointestinal tract with stable resonance frequency. Also, proper receiving coil models were proposed based on the power and size requirements of the colon robot moving in the hu- man body and the uncertainty of its posture and position in transmitting coils. Eight types of receiving coils with the same shape and size, were made with different number of strands. The ten-stranded coil was eventually chosen by comparing the receiving efficiency of the above eight types. Thus, wireless pow- er transmitting system for colon robot was presented and its feasibility was validated in the experiments.
