Animated human walking movement for body worn antenna study

This paper presents how an animated human model with walking movement has been created and used in the body worn electromagnetic simulation software, XFdtd. A 3D-surface scan of a human body has been combined with the walking movement captured using a motion capture system to generate the animated model. A comparison between measurement results taken on the real human subject and simulation results from the created animated model of the same human subject is examined to select the appropriate mesh size and material representing the body and antennas. The effect of body gesture on the on and off-body radio channels has been investigated with the ultimate aim of reducing transmit power between antennas.
