Receiving Coil Analysis of Wireless Power Transmission with Inductive Coupling

The inductive coupling scheme delivering wireless power which can replace the battery in capsular endoscope(CE) is described in this paper. The characteristic of the magnetic flux linkage coil which generates the induced emf under a magnetic field is analyzed. With the analyzed results, a magnetic flux linkage coil system is fabricated and tested. It was confirmed that the magnetic flux linkage coil system could supply more than 50 mW power without changing the structure of conventional CE.
