摘要：

目的無(wú)線供能系統(tǒng)的接收裝置囿于尺寸限制難以滿足越來(lái)越高的能量要求，提高空間利用率是解決這一難題的關(guān)鍵。方法從接收裝置的姿態(tài)穩(wěn)定性和體內(nèi)溫升安全性角度出發(fā)，通過(guò)實(shí)驗(yàn)方法確定接收裝置磁芯的較優(yōu)形狀，并在給定尺寸約束下根據(jù)幾何關(guān)系建立方程解出磁芯尺寸與導(dǎo)線股數(shù)和匝數(shù)，從而實(shí)現(xiàn)接收裝置的結(jié)構(gòu)優(yōu)化。應(yīng)用該方法對(duì)腸道機(jī)器人無(wú)線供能模塊的能量接收裝置進(jìn)行了設(shè)計(jì)和實(shí)驗(yàn)。結(jié)果在外形≤10mm×10mm的約束下，接收裝置輸出功率可以保證在500mW以上，并且符合溫升安全性要求。結(jié)論實(shí)驗(yàn)結(jié)果表明了這種帶約束的對(duì)稱性設(shè)計(jì)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.
