Wearable Antennas for Sensor Networks and IoT Applications: Evaluation of SAR and Biological Effects.
This in vitro study evaluated SAR and erythrocyte membrane stability during exposure to a fully textile wearable antenna at 2.41 GHz under realistic (6.3 mW) and conservative (450 mW) input power conditions. It reports 1 g average SARs of 0.5758 W/kg and 41.13 W/kg, respectively. For membrane stability at 6.3 mW, short-term exposure (20 min) was reported as stabilizing, while longer exposure (120 min) was reported as destabilizing.
Key points
- The study investigates RF exposure from a fully textile wearable antenna intended for IoT wearable devices.
- Exposure frequency was 2.41 GHz and irradiation occurred in the reactive near-field of the antenna.
- Reported 1 g average SAR was 0.5758 W/kg at 6.3 mW net input power.
- Reported 1 g average SAR was 41.13 W/kg at 450 mW net input power.
- At 6.3 mW, 20 min exposure was reported to stabilize erythrocyte membranes.
- At 6.3 mW, 120 min exposure was reported to destabilize erythrocyte membranes.
