We are now aiming to supply power to the capsule endoscope by non-contact wireless power transmission, and we have found that the transmission efficiency can be greatly improved by making coils using high-frequency superconducting wires that can achieve low loss at high frequencies, which we have developed. In this study, we report on the design of a high Q-value coil using high-frequency superconducting wires in a solenoidal coil with a uniform magnetic field distribution so that the transmission efficiency does not change significantly depending on the position of the capsule endoscope.
