Abstract

This paper introduces a strategy how to determine the number of turns of the receiving coil for in vivo robotic capsules to maximize the regulated load power. For the expected functionality additional to the endoscopic function, it is necessary to employ wireless power transmission and increase the receiving power to a maximum. The functional relation between the number of turns and the power is derived and verified by implementing a ferrite-loaded receiver coil.
