Abstract

Overview

The rapid expansion of novel technologies today is resulting in increased exposure to radio frequency (RF) energy with varying wavelengths and power levels. There is a compelling need for updated methods to measure RF energy in complex environments, especially within biological tissues.

Findings

  • This study introduces a new technique for the direct in-vivo measurement of electric fields in living tissue.
  • Proof of concept was demonstrated through experiments in rodent brains, employing Bismuth Silicon Oxide (BSO) crystals subjected to different levels of RF energy.
  • The accuracy of electric field measurements was validated using in-vivo temperature assessments and electromagnetic field simulations in a transverse electromagnetic (TEM) cell.

Conclusion

This research is crucial as accurate dosimetry of absorbed RF electric fields by live tissue is a key aspect of environmental health considerations for the proliferation of non-ionizing radiation energy.
