Abstract

The specific absorption rate (SAR) determined by a wearable heart rate monitor device (HRMD) is computed. A full wave finite difference time domain (FDTD) code is adopted to compute the electromagnetic field inside a high resolution body model accounting for the permittivity and conductivity values of all human tissues. Also the antenna of the device is accurately modeled by the FDTD code. The percentage of power deposition in each single tissue is recovered. The code running on a supercomputer allows to repeat quickly a lot of simulations, showing the not negligible dependence of SAR values according to the device positioning on the body.
