Numerical analysis of the thermal effects on adult with brain pacemaker implantation exposed to WIFI antennas
This numerical study modeled RF exposure from WiFi/5G-type antennas near a 3D brain model with implanted brain pacemakers relevant to Parkinson’s disease. SAR and temperature increases were reported to remain below ICNIRP 2020 limits across modeled conditions, with maxima at a 90° antenna-to-brain angle. Despite compliance with SAR/temperature limits, the authors report modeled thermal strain and tissue displacement that could affect postoperative efficacy, leading them to recommend caution and increased distance from phones.
Key points
- A COMSOL finite-element 3D brain model with basal ganglia, dual-frequency PIFA antennas, and implanted brain pacemakers was used.
- SAR and brain temperature rise were reported to stay below ICNIRP 2020 limits under all modeled frequencies and angles.
- Peak SAR/temperature occurred when the antenna-to-brain angle was 90°.
- Grey matter thermal conductivity and electrode geometry altered temperature-rise trends in the simulations.
- The study reports thermal strain and tissue displacement during heating that could impact postoperative efficacy.
- The magnitude of modeled displacement was described as consistent with prior medical literature values.
- The authors recommend avoiding phone positions corresponding to a 90° antenna-to-brain angle and maximizing distance from phones.
- The authors suggest monitoring/regular hospital visits for frequent phone users with brain pacemakers.
