Abstract

Overview

This paper strategically explores the absorption of electromagnetic energy by smartphones through a detailed simulation using COMSOL Multiphysics software. The specific absorption rate (SAR) of electromagnetic fields (EMFs) on the human brain is the focal point of this inquiry. Particular attention is paid to how smartphones' emission patterns affect SAR levels.

Findings

  • The computational model validated that prolonged smartphone usage can alter brain function, potentially leading to fatigue and stress.
  • Significant changes in brain activity linked to electromagnetic absorption were observed, particularly in EEG signals across specific brain regions during smartphone use.
  • The model suggests a direct correlation between high SAR levels and notable changes in brain electrical activities.

Conclusion

The study concludes with a verification of how EMF absorption via smartphone usage corresponds with alterations in brain activity, reflected in EEG signal analyses. The congruence between high absorption spots and significant EEG changes underpins concerns about EMF exposure. Plans for future studies include focusing on excessive smartphone use among youths.
