Comparison of 3D scanned human models for off-body communications using motion capture

Abstract: Body area networks are complex to analyze as there are several channel mechanisms occurring simultaneously, i.e. environmental multipath together with body motion and close coupling between worn antennas and human tissue. Electromagnetic (EM) simulation is an important tool since not all studies can be done on a real human. In order to gain insight into off-body communication involving a worn antenna, this paper uses a 3D animated model obtained from a 3D surface scanner and a motion capture system for full wave simulation of channels at 2.45 and 5.5GHz. To evaluate if the model can represent body area radio channels in general, a comparison of S21 of the simulated model with measurements from 5 other models of similar height to the main test subject is presented.

Evaluation of 3D animated human model from 3D scanner and motion capture to be used in electromagnetic simulator for body-centric system

Abstract: 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.

Novel Millimeter-Wave Antenna Array Using Half Mode Substrate Integrated Waveguide (HMSIW)
