Abstract: An underwater wireless charging method and device using acoustic waves for covering the entire depth of sea is disclosed. Within 10 meters below the water-level, unmanned undersea vehicles (UUV) are charged from a mother ship . Between 10 meters and 100 meters below the water-level, a sound wave is directly sent from the mother ship to the underwater sensor to be charged. At the depth of more than 100 meters below the water-level, an underwater UUV is adopted to in situ charge the underwater sensor node at close range. The transmitting transducer converts electrical energy to sound energy through the inverse piezoelectric effect. The sound wave is then sent by the transducer to a hydrophone that transforms sound energy to electrical energy via the piezoelectric effect. The load can thus be charged. Three types of wireless charging can be realized by the station for different underwater application scenarios, so as to satisfy the wireless charging for covering the entire depth of sea.
