Personal distributed exposimeter for radio frequency exposure assessment in real environments

Abstract

For the first time, a personal distributed exposimeter (PDE) for radio frequency (RF) measurements is presented. This PDE is designed based on numerical simulations and is experimentally evaluated using textile antennas and wearable electronics. A prototype of the PDE is calibrated in an anechoic chamber. Compared to conventional exposimeters, which only measure in one position on the body, an excellent isotropy of 0.5dB (a factor of 1.1) and a 95% confidence interval of 7dB (a factor of 5) on power densities are measured. © 2013 Wiley Periodicals, Inc.
