Wireless BAN for Intra-Body Communications Human Body as Transmission Medium

S. Wilfred Franklin, Dr.S. Edward Rajan, J.A. Alex Rajju Balan

Abstract


Intra-Body Communication in which the human body is used as a signal transmission medium is a new approach which enables wireless communication without transmitting radio waves through the air. This approach is driven by the vision of a cable-free biomedical monitoring system. With this new idea of transmitting data through the human body, various attempts have been made to model the human body as transmission medium through which wireless transmission is achieved.  Such a new wireless data communication technology will offer substantially increased freedom for long-term risk patients. On body sensors in the form of intelligent band-aids monitor the human vital functions and transfer data through the human body to a central monitoring unit. This recorded data will be transferred wireless through the body within the Body Area Network (BAN) sensor nodes, which is enabled by the Intra-Body Communication capability of every sensor. The single node which acts as the central monitoring node is connected by a traditional wireless link to the remote hospital monitoring infrastructure, where the data will be displayed or stored in the patient’s record. This electronic data transfer through the human body has been proposed by research and industry as a promising technology for ultra low power Wireless Body Area Networks.
