摘要
We have proposed a human-area net technology that uses the surface of the human body as a data transmission path and uses an AC electric field signal below the resonant frequency of the human body This technology aims to achieve a "touch and connect" intuitive form of communication by using the electric field signal that propagates along the surface of the human body. while suppressing both the electric field radiating from the human body and mutual interference To suppress the radiation field. the frequency of the AC signal that excites the transmitter electrode must be lowered, and the sensitivity of the receiver must be raised while reducing transmission power to its minimally required level We describe how we are developing AC electric field communication technologies to promote the further evolution of a human-area network in support of ubiquitous services, focusing On three main characteristics. enabling-transceiver technique, application-scenario modeling. and communications quality evaluation Special attention is paid to the relationship between electro-magnetic compatibility evaluation and regulations for extremely low-power radio stations based on Japan's Radio Law
