Body-worn physiological sensors can facilitate ambulatory patient monitoring, particularly if communication between sensors is wireless; but the communication channel must be robust. This paper presents how a 3D animated human model is created using a 3D scanner and a motion capture system. Then this model is used in XFdtd, electromagnetic simulation software to obtain body worn channel properties. Three walking gestures from the created model, wearing dual band metallic button antennas, DBMBAs, were simulated and compared with the original measurements carried out on the real test human model. Furthermore, verification of the 3D animated model was achieved by comparing the simulation results of the main test model with measurements from 5 additional test models.
