Electromagnetic Assessment of UHF-RFID Devices in Healthcare Environment

In this work, the evaluation of electromagnetic effect Ultra High Frequency Radio Identification (UHF-RFID) passive tags used in healthcare environment is presented. order to evaluate exposure levels caused by EM field (865–868 MHz) UHF-RFID readers, measurements an anechoic chamber and a real medical (Hospital Universitario de Canarias), as well simulations 3D Ray Launching algorithm, biophysical effects human models are The results obtained show that localized, close vicinity RFID reader inversely proportional its reading range. detected sufficient cause immunity electronic devices (malfunctions equipment or implants). Moreover, more than negligible direct humans (exceeding relevant SAR values) were found only next reader, up approximately 30% As consequence, risk could be firstly evaluated based on parameters, but should include situ assessment. It requires attention additional studies, increased applications monitoring systems observed sector—specifically when any system located workplace permanently occupied.
