Abstract

Overview

This paper discusses the absorption of electromagnetic energy by smartphones and its impacts. Detailed modeling using COMSOL Multiphysics software helps in understanding these effects specifically within the human brain.

Findings

• The study investigates specific absorption rates (SAR) in the depth of the human head.
• Technical parameters of smartphones and human brain biological characteristics are carefully modeled.
• A significant discovery relates to brain activity changes linked to different SAR values, examined via EEG signal analysis. Changes in brain activity could lead to fatigue, distraction, and stress.
• Locations of highest EMF absorption showed substantial alterations in EEG spectra, potentially indicating adverse brain effects.

Conclusion

The article concludes highlighting that high SAR levels from smartphone usage can cause notable brain activity changes. It emphasizes the need for further research, especially concerning the impacts on children and adolescents.
