Abstract (in Japanese) (See Japanese page) 
(in English) We have been studying wireless power transfer for robot fish in an aquarium. Though we have chosen 1MHz for the operating frequency so far, it turned out that we can reduce the dangerously high voltage by decreasing the Tx resonator frequency to 100kHz. Therefore we have studied the variation of the coupling coefficient and unloaded Q of the resonators due to the frequency, and then looked for the possibility of system operation optimization by operating frequency.
