Overview of Intra - body Communication Research

As an important component in the wireless communication and the wireless sensor network, the intra-body communication can be used to improve the people’s healthcare level through applications of intelligent information processing and wireless signal transmission technology etc., and increasing attention is being paid to the communication technology by relevant researchers and enterprises. At present a great many research results on the intra-body communication have been achieved. In this paper, the existing research results are summarized; then they are classified and summed up based on coupling modes of the intra-body communication, with sufficient discussion. Due to less environmental impact and steady signal transmission in the current coupling intra-body communication only, a selective analysis is made for advantage and shortcoming of existing achievements on the field in this paper. Meanwhile, the property that the quasi-static condition in the current coupling intra-body communication within the high frequency area is not valid is proposed, to point out the direction for further research.
