摘　　要：针对目前胶囊内窥镜受到能量限制的问题,设计了一种基于无线供能的微型化、低功耗的图像胶囊内窥镜.对无线供能电路,图像传感器电路,无线发射电路进行设计研究,搭建了无线能量传输系统平台,制作了无线供能图像胶囊内窥镜样机,并通过实验验证了无线能量传输系统发射线圈设计的合理性.通过与医院合作的猪大肠内部图像采集实验,验证了研制的图像胶囊系统样机的可行性.完整的图像胶囊内窥镜的尺寸仅为510mm@20mm,图像传感器电路和无线发射电路的整体功耗最低约为65mW.In view of the limit of energy in capsule endoscopy,this paper reports a miniature image capsule endoscopy with low power consuming based on wireless power. A wireless energy circuit,an image sensor circuit and a transmitting circuit are de- signed and studied; a wireless energy transmission system platform is built; a wireless powered image capsule endoscopy prototype is made,and tests are made to prove the rationality of the wireless energy transmission coil. The feasibility of the whole system is proved by image acquisition experiment in the pig intestinethrough cooperation with the hospital. The total size of the image capsule endoscopy prototype is only φ10mm x 20ram, and the power consumption of image sensor circuit and transmitting circuit is 65roW when the modules are connected.
