Multifunctional underwater sensors with integrated self-powered signal transmission, effective thermal-moisture regulation, and multi-signal decoupling are desirable of underwater tasks. Here, the authors report a three-dimensional thermoelectric device composed of porous polyurethane foam coated with a waterproof conductive layer for human-machine interaction in aquatic settings.
