THz Spectroscopy

Molecular Fingerprint Chemical Sensing

Using terahertz electromagnetic waves to detect and identify hazardous gases, explosive molecules, and biological pathogens via unique absorption lines.

Technical Explanation

Molecules exhibit rotational and vibrational quantum resonances that fall precisely within the 0.3 THz to 10 THz frequency range. When a 6G THz signal passes through air containing trace amounts of carbon monoxide, cyanide, or biological viral particles, the molecules absorb specific spectral frequencies, creating an unmistakable 'spectral fingerprint'. 6G devices can thus perform environmental safety monitoring and medical breath analysis continuously.

Key Functions

  • Detecting trace concentrations of hazardous industrial gases and toxic airborne chemicals
  • Non-destructive quality inspection of pharmaceutical pills, food freshness, and packaging
  • Contactless breath analysis detecting biometric disease biomarkers in exhaled air
  • Simultaneous wireless data transmission while interrogating ambient air chemistry
  • Integrated spectroscopic database matching detected absorption lines against known chemicals
