The high-speed human body communication system

A review of research about human body communication was begun from a proposal [1] by Zinmerman of MIT (Massachusetts Institute of Technology) in 1995. Specifically, over the past few years, a considerable number of studies have examined human body communication. Practical use was researched about a wearable key [2] and the POS (point of sale) system [3]. In addition, a project called RedTacton [4] was begun. On the other hand, a detailed electromagnetic analysis about the propagation structure of the human body was reported [5]. However, only a few attempts have been made to accelerate the human body communication system. This paper investigates the acceleration of the human body communication system. First of all, we examined the already known method of the human body communication system. Next, we investigated the electromagnetic characteristics of the human body for use as a transmission line.
