The video capsule endoscopy (VCE), as a new technology, has been increasingly popular for diagnosis of gastrointestinal (GI) tract diseases. Limited by the power supply, however, most of capsule endoscopies can only work for 6 to 8 hours at a frame rate of 2 frames per second (f/s). Based on electromagnetic induction, the wireless power transmission (WPT) system can provide a power of 150mW at a frequency of 218 KHz for the VCE in the body. The transmitting module adopts a solenoid pair structure with a uniform internal magnetic field and the receiving module a three-dimensional coil structure at a working frequency of 218 KHz. The result showed that the VCE can work properly and transmit a 30fps NTSC video with the resolution of 320×240. Such wireless power supply approach provides power support for the further development of VCE technology.
