Abstract

Overview

Mobile phones, now indispensable in modern society with escalating global usage, operate at multiple frequency bands that could potentially harm human tissues.

Model Development

• Introduction of an in silico model using COMSOL® Multiphysics for simulating thermal effects in the human auricle region from mobile phone use.
• Components like lithium ion batteries, CPUs, and antennas are included to analyze both radiative and non-radiative heating sources.

Findings

• Simulation of mobile phone heating during calls validated against experimental data indicates the highest temperature increase at 1800MHz.
• Comparative analysis with clinical thermographic images shows qualitative and quantitative agreements.
• Heating effects dominated by the CPU, but deeper penetration by antenna heat indicates potential for serious soft tissue and brain temperature effects.

Conclusion

This model underlines the crucial role of phone design in preventing potential negative health impacts from thermal effects, advocating for personalized and preventive medicine techniques like thermography.
