我们提出了一种利用人体表面作为数据传输路径，并使用低于人体谐振频率的交流电场信号的人体区域联网技术。这项技术旨在通过利用沿人体表面传播的电场信号，同时抑制从人体辐射出来的电场和相互干扰，实现一种“触摸连接”的直观交流形式。为了抑制辐射场，必须降低激励发射器电极的交流信号的频率，并且必须提高接收器的灵敏度，同时将发射功率降低到其最低所需的水平。我们描述了如何发展交流电场通信技术，以促进支持泛在服务的城域网络的进一步发展，重点介绍了使能-收发技术、应用场景建模和通信质量评估三个主要特征。特别注意电磁兼容性评估与基于日本《无线电法》的极低功率无线电台法规之间的关系。
We have proposed a human-area networking 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.
