Red Tacton is a new human area network technology developed by Japanese company NTT that uses weak electric fields on the surface of the human body for high-speed network transmission. It works by creating changes in electric fields from a transmitting transceiver that are received by a sensing receiving transceiver. Data transfer is faster and more secure compared to other technologies, though it has a limited range of a few centimeters and is more costly. Potential applications include touch-based controls and transferring various media types through the human body.
