Cross-medium communication is a key technology in integrated sea-land-air networks. Due to the attenuation characteristics of communication signals in cross-medium environments and the interference of obstacles, achieving cross-medium communication has always been an important and challenging issue. This study proposes a novel method for cross-medium wireless communication based on Maxwell displacement current generated by a Triboelectric Nanogenerator (TENG). By connecting TENG to an emitter plate and using a pair of coupling plates to facilitate the transmission of Maxwell displacement current, the generated electric field successfully traverses both air and water mediums. Through both simulation and experimental methods, we systematically studied the impact of electrode factors and environmental factors on the transmission characteristics of the electric field signals. Compared to traditional cross-medium communication methods, this method demonstrates excellent anti-interference capabilities, being almost unaffected by obstacles and the attenuation caused by seawater absorption. This approach, based on Maxwell displacement current generated by TENG, offers a novel wireless communication method in complex air-water cross-medium environments.
