Intra-body communication in biomedical applications

The paper presents a new concept of communication method called as Intra-body communication in biomedical field. Human body is used as a medium of transmission of data. The use of this technology in medical monitoring systems eliminates the complexity of existing technologies that involves cables, wires for transmission of data. The proposed model provides a secure and simple communication system that consists of wearable devices to measure heart-beat and temperature and hence transmits the data to the master device in real time. The model, wearable on wrist or any other part of the body has an integrated processor ARM7 and an insulating material (copper) to allow the intra-body communication using the method of galvanic coupling. Thus the proposed methodology of using human body enhances the security of transmitted signals as compared to the other wireless technologies.
