Remote Sensing of Biometric Signatures Including Stress Levels and Alertness

Feldman Yuri, HUJI, School of Computer Science and Engineering, Applied Physics

Through electromagnetic radiation from skin


Homeland Security,  Medical diagnostics

Development Stage

Proof of concept established in laboratory


  • Method allows monitoring the electromagnetic radiation in sub-terahertz frequency range reflected and emitted by skin
  • Biometric signature determined from sweat gland activity used in diagnosis of a person’s physical and emotional health; each individual’s skin organ specificity gives rise to unique electromagnetic fingerprint.
  • Homeland security: identifying suspects about to commit dangerous act.  Medical diagnostics: certain diseases cause unusual activity in sweat glands.  Drug control:  check for presence of drugs in the body.  Identification:  ID individuals through unique patterns of sweat glands in the skin.

Our Innovation

Method for passive detection of electromagnetic waves emanating from the skin in defined frequency ranges. Technology based on existing methods of microwave reception and transmission, combined with proprietary software, data treatment, and antenna design.

Key Features

  • Non-invasive
  • Specifics of spectral response of skin are highly correlated with level of physical and mental state of activity of subject

Development Milestones

  • Passive and active measurements in specified frequency range (75-110 GHz) demonstrated promising results
