The study of wireless power transmission under water-to-air mode

Abstract

This research proposes the preliminary study whether the power transmission is possible or not. The wireless power transmission using particular resonance technique with series resonance for transmission and parallel resonance for receiver has been proposed. The study is focused on the wireless power transmission on waterto- air mode on reversed osmosis water and various salt water concentrations. The transmitted power is up to 7 W at a frequency of 6.78 MHz across a distance in the range between 10 mm to 60 mm has been demonstrated. Finally, the effect of water type and the percentage of salt concentration on wireless power transmission attenuation are presented and analyzed.
