Abstract. In the last two decades, the increasing number of electronic devices used in day-to-day life led to a growing interest in the study of the electromagnetic field interaction with biological tissues. The design of medical devices and wireless communication devices such as mobile phones benefits a lot from the bio-electromagnetic simulations in which digital human models are used. The digital human models currently available have an upright position which limits the research activities in realistic scenarios, where postured human bodies must be considered. For this reason, a software application called "BodyFlex for CST STUDIO SUITE" was developed. In its current version, this application can deform the voxel-based human model named HUGO (Dipp GmbH, 2010) to allow the generation of common postures that people use in normal life, ensuring the continuity of tissues and conserving the mass to an acceptable level. This paper describes the enhancement of the "BodyFlex" application, which is related to the movements of the forearm and the wrist of a digital human model. One of the electromagnetic applications in which the forearm and the wrist movement of a voxel based human model has a significant meaning is the measurement of the specific absorption rate (SAR) when a model is exposed to a radio frequency electromagnetic field produced by a mobile phone. Current SAR measurements of the exposure from mobile phones are performed with the SAM (Specific Anthropomorphic Mannequin) phantom which is filled with a dispersive but homogeneous material. We are interested what happens with the SAR values if a realistic inhomogeneous human model is used. To this aim, two human models, a homogeneous and an inhomogeneous one, in two simulation scenarios are used, in order to examine and observe the differences in the results for the SAR values.

A post-tsunami evacuation simulation using 3D kinematic digital human models (KDHs) and its experimental verification are addressed in the present study. Methods for carrying or assisting (transporting) injured people were experimentally investigated and the results were used for KDH data calibration to increase the accuracy of the simulations. It was found that, on flat ground, both the transit speed and the amount of time spent on intermittent rests were strongly affected by the load on the transporters. During ascent of stairways, the transit speed depended on the type of carry method being used, and decreased in the order saddleback carry, two-person arm carry and slightly injured walking. Several KDH evacuee motion primitives were developed for stairway ascent to a tsunami evacuation tower. The simulation results show that the evacuation time was affected by the number of evacuees and the congestion due to the transportation of injured people. The developed simulation techniques can be effectively utilized in the planning of tsunami tower evacuation and predicting related crowd behavior.
