Research on the robot inside the body equipped with various features, such as therapeutic function and self-propelled capability within the capsule endoscope is performed. Research on Wireless Power Transfer for robot inside the body to act sufficient in the body is performed, because internal battery has a limit of the capacity. It is necessary to reduce an electromagnetic field because electromagnetic field is generated from a Wireless Power Transfer. Power transmission in the Wireless Power Transfer depends largely on the quality factor of the coil and the transmission frequency. In this paper, it is shown that it is possible transmission power of 30 mW in the range of 300 mm × 300 mm × 180 mm, while reducing an electromagnetic field in the frequency 700 kHz.
