Intra-body Body Communication (IBC) is a communication technology in which human body is used as a signaltransmission medium. Due to its unique characters, IBC technology is proposed as a novel and promising technology forpersonal area network (PAN), computer network access, implant biomedical monitoring, human energy transmission,etc. In this paper, investigation has been done in the computer simulation of the electrostatic coupling IBC by using thedeveloped finite-element models, in which (1) the incidence and reflection of electronic signal in the upper arm modelwere analyzed by using the theory of electromagnetic wave, (2) the finite-element models of electrostatic coupling IBCwere developed by using the electromagnetic analysis package of ANSYS software, (3) the signal attenuation ofelectrostatic coupling IBC were simulated under the conditions of different signal frequency, electrodes direction,electrodes size and transmission distance. Finally, some important conclusions are deduced on the basis of simulationresults.
