Abstract

Overview

The study addresses the safety concerns related to electromagnetic fields generated by smart glasses and their interaction with the human head.

Findings

  • Smart glasses employing WiFi or Bluetooth connectivity pose potential risks through electromagnetic radiation exposure.
  • Simulations were used to evaluate different scenarios involving changes in antenna types, positions, and frequency on the specific absorption rate (SAR) in human head tissues.
  • While antenna type showed minimal impact, antenna placement and frequency were instrumental in affecting SAR values.

Conclusion

Evidence strongly suggests that the relative safety of smart glass wear can be enhanced by optimizing antenna positioning. Placing the antenna at the front significantly reduces risk by increasing distance from critical head tissues.
