Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this report is to achieve non-contact feeding of electric field-coupled electrodes to robot fish in a tank. In this case, all four electrodes used for the tank and the robot fish face the water, so that the nature of the water between the electrodes has a great influence on the feeding of electricity. In particular, the electrical conductivity and permittivity of water are related to the loss and coupling coefficient of the power supply system, respectively. The dielectric constant of water should rarely change due to impurities and other factors, but the conductivity of water fluctuates greatly. In this report, we mainly focus on the electrical conductivity and analyze its advantages and disadvantages as much as possible to improve the transmission efficiency.
