Smartphone Micro-Spectroscopy Sensor

Handset Terahertz Absorption Spectrum Analyzer for Chemical Identification

Utilization of the smartphone's sub-THz transceivers to detect material composition, food freshness, and air pollutants via molecular resonance.

Technical Explanation

Many chemical compounds, organic molecules, and gases exhibit unique electromagnetic absorption fingerprints ('molecular resonance lines') in the 100 GHz to 1 THz region. By aiming the smartphone at food, liquid, or ambient air and emitting frequency-swept sub-THz probing signals, the receiver measures the absorption spectrum. On-device chemometric AI algorithms match the spectral dip against reference databases to detect food spoilage, pesticide residues, skin hydration, or counterfeit medications.

Key Functions

  • Identifies chemical composition and molecular fingerprints contactlessly
  • Measures food freshness, glucose levels, and liquid purity in seconds
  • Detects toxic airborne gases and pollutants without chemical test strips
  • Turns ordinary smartphones into handheld laboratory-grade spectrometers
