A patient interface device comprising a cushion and a frame and housing member coupled to the cushion. The frame and housing member includes a pressure generating system structured to generate a flow of breathing gas and is in fluid communication with the cushion. The frame and housing member also includes an antenna and RF energy harvesting circuitry coupled to the antenna, wherein the antenna is structured to receive RF energy and provide the RF energy to the RF energy harvesting circuitry, and wherein the RF energy harvesting circuitry is structured to convert the RF energy into usable energy for powering the pressure generating system.
