Abstract

Overview

The study critically examines the interaction between microwave radiation, specifically in the sub-terahertz (THz) band, and human skin. Traditional views consider the skin merely as a passive, absorbing layer but recent findings suggest a more complex interaction.

Findings

• The coiled part of the sweat duct in the upper skin layer behaves like a helical antenna at sub-THz frequencies.
• Reflectance of human skin in this frequency range varies with perspiration levels and correlates with stress.
• Simulated models reveal a high specific absorption rate (SAR) due to the helical structure of the sweat duct.
• Correlations between the skin's sub-THz properties and human health markers like ECG have been observed.

Conclusion

The implications of extensive 5G deployment and the potential health risks associated with increased exposure to sub-THz frequencies merit serious consideration. Given these findings, a cautious approach to the rollout of 5G technology is recommended, particularly due to the specific resonance of sweat ducts with these wavelengths.
