人体通信技术研究进展

人体通信是一种利用人体作为信号传输途径的新型非射频无线通信技术，被设计用于进行医疗传感器网络间的通信。在2012年批准的无线体域网标准IEEE802156中，人体通信与窄带通信、超宽带通信一同被规定为搭建无线体域网的三种方法。人体通信依据耦合方式的不同可分为两种基本类型：电容耦合和电流耦合。文中首先对这两种类型的人体通信原理进行了介绍；之后详细说明了人体通信技术的产生、发展及现状，并通过与其他技术的对比总结了其优势与不足；最后指出了其未来发展的3个重要方向：植入式设备的人体通信、人体通信无线供能和磁场耦合式人体通信。

Research Progress of Human Body Communication Technology

Human body communication is a new non radio frequency wireless communication technology using human body as the signal propagation path, designed for the communication between healthcare sensor network systems. It is one of three standard methods of wireless body area networks in the IEEE 802156. Human body communication can be classified into two basic types by different coupling: the capacitive coupling and the galvanic coupling. The principle of these two types of human body communications was presented firstly. Then the invention, the development and the actuality of human body communication technology were explained in details, and its strengths and weaknesses were summarized by comparing with other technologies. In the end, three important directions of future development were proposed including the human body communication of implanted devices, the human body communication for wireless power transfer and the human body communication base on magnetic coupling.
