A Study of Factors Affecting Wrist Channel Characteristics for Walking Postures Using Motion Capture

The creation of a 3D animated human model (avatar) to be used in electromagnetic (EM) simulation software is described for low outage body area network application such as healthcare. Scanned surface data of a human model is combined with movement data from a Motion Capture system to simulate an on-body channel between two dual band metallic button antennas (DBMBAs) mounted on the wrist and chest and the wrist and hip during walking. An investigation of how different factors such as human geometry parameters, arm swing and wrist twisting can affect the body-centric channel during walking action is presented together with the relative significance of each of these factors on predicting body-centric channel gain.
