Abstract The principle of a wireless power transmission(WPT) and the basic constitutions of the capsule micro-electro-mechanical systems(MEMS) were introduced. Then, based on a loosely coupling transformer, the WPT system of the capsule MEMS were designed. The secondary receiving windings composed of two orthogonal coils received power after experiment research. The results show that regardless of the capsule location, the secondary can receive effective power, up to 110-240 mW. At last the luminous capsule model prototype was made, and the luminous capsule can work by WPT. It shows the WPT system is feasible．

胶囊微机电无线能量传输系统设计与试验研究
首先介绍了胶囊微机电无线电能传输系统的原理和系统的基本构成,然后设计了以松耦合变压器为基础的无线电能供给系统,采用互相正交的二维线圈来接收能量并进行试验研究.结果表明：不管体内微机电系统处在何种位置和姿态,都可以有效接收能量,特别在初级绕组窗口宽度内,次级绕组接收能量可以高达110~240 mW．最后研制了胶囊微机电无线能量传输系统样机,可以成功驱动胶囊微机电系统工作,表明了该胶囊无线电能传输系统设计是可行的．
