Document Type and Number:
WIPO Patent Application WO/2020/050183
Kind Code:
A1
Abstract:
Provided are an underwater communication device and an underwater communication method that can be applied to underwater mobile communication. The underwater communication device 10 is provided with a transmitter 12 which emits an electric signal, and a receiver 14 which is disposed away from the transmitter 12 with water therebetween, and receives the electric signal. The receiver 14 comprises a field-effect transistor 23 with a channel region 39 disposed in a position in contact with the water, and a drive circuit 26 which produces a potential difference between a source region 31 and a drain region 33 of the field-effect transistor 23.
