Abstract
The skin response to high radio frequency has been
associated with the human physical condition and most
prominently with the stress. The objective of this study is to
investigate the possibility to detect mental and light physical
stress through the measurement of skin reflectance in the mm-
wave/sub-THz band. Two frequency bands have been
considered, 75-110 GHz (Band-I) and 325-500 GHz (Band-II),
while the measurements have been performed in the three
different locations, the arm, the dorsal side of the hand and the
fingertip. The measurement setup is discussed in detail and the
reflectance spectrum is demonstrated. The results illustrate a
difference in skin reflectance under rest and stress in Band-II
which ranges from 3.5 dB at the finger to 7 dB at the hand. The
outcomes of this study indicate the feasibility of stress detection
through skin reflectance measurement and serve as a suggestion
for deeper exploration of higher frequency bands.
