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.
In order to make the colon robot get rid of the power supply cable and penetrate into the intestine, a wireless power supply device is developed, which based on the principle of electromagnetic coupling, can generate a uniform alternating magnetic field of fixed frequency in the human gastrointestinal tract area, In the human body movement power requirements, attitude and position of the uncertainty and size requirements, designed a suitable receiver coil model.With different numbers of windings made of eight kinds of receiver coil of the same size, the comparison of each coil Receive the efficiency, and finally choose the coil made of 10 strands.A practical wireless energy transmission system for the energy supply of intestinal robots was established, and its feasibility was verified.
