Smart Electronic Device-Based Monitoring of SAR and Temperature Variations in Indoor Human Tissue Interaction

Abstract

Overview

With the proliferation of electronic devices, regular exposure to electric and magnetic fields in home and work environments raises concerns about human overexposure.

Key Points:

• The study evaluates the effects of electric fields on human health across both low and high frequency ranges.
• It introduces an electronic monitoring device designed to capture Specific Absorption Rate (SAR) and temperature change (ΔT) within human tissue.
• Collected data is uploaded to a cloud platform, where it is processed with a feedforward neural network (FFNN).
• Monitoring was conducted in indoor settings with both stationary and moving subjects.

Findings

• The monitoring device effectively maps temperature distribution changes caused by electromagnetic field exposure.
• Temperature peaks and elevated SAR values were detected, particularly when subjects were immobile.
• Predictive modelling highlights the importance of workplace shielding (using specific materials) from external electromagnetic signals and for dampening internal sources.
• Limiting mobile phone use was shown to decrease both SAR and tissue temperature.

Conclusion

This study underscores the potential health risks from overexposure to electromagnetic fields due to regular use of electronic devices indoors. Real-time monitoring demonstrates that SAR and tissue temperature can rise to concerning levels, especially when individuals remain stationary. Shielding materials and prudent mobile device usage are recommended measures to mitigate EMF exposure and associated health risks.
