title: Dual-head wireless powered video capsule based on new type of receiving coils.
abstract: Wireless capsule endoscopy (WCE) has been a great breakthrough in visually detecting the pathological changes of gastrointestinal (GI) wall, but the limit of viewing angle and power by batteries still hinder the wide application of WCE. In order to address these shortcomings, a dual-head video capsule system based on new type of receiving coils is presented. First, the dual-head video capsule system is designed, which could capture images of the whole GI tract in two channels, transforming the images into NTSC videos at a frame rate of 30 f s(-1) and transmitting the signals outside the body. Second, the wireless power transmission platform with new type of receiving coils is established to provide at least 108 mW of continuous, stable energy for the capsule. Then a prototype was fabricated and applied in animal experiments. The designed dual-head video capsule system is proved to be feasible and a potential solution for future clinical application.
