Abstract

In order to solve the problem of energy limitation in capsule endoscopy, the button battery can be replaced by an external wireless power. A small wireless power transfer system for delivering power to capsule endoscopy has been presented here. The wireless power transfer system is built by using a small cylindrical receiving resonator and two cylindrical source resonators to transfer power through coupled magnetic resonance. Experimentally, it is found that the wireless power transfer efficiency is stable within a certain range due to the stable magnetic field generated by two source resonators. The proposed design has the significant advantage of stable power transfer and small size for capsule endoscopy.
