Area of Science:

  • Acoustic wave physics
  • Chemical sensing technology
  • Materials science

Background:

  • Surface acoustic waves (SAW) are efficiently converted to bulk waves using periodic gratings.
  • Grating structures on opposite piezoelectric plate surfaces enable directed SAW propagation.

Purpose of the Study:

  • To design and explain grating-based SAW sensors for chemical analyte detection.
  • To investigate the mass sensitivity of these sensors using polymer films.
  • To demonstrate the sensor's capability for detecting nitrogen dioxide (NO(2)) at low concentrations.

Main Methods:

  • Fabrication of periodic gratings on piezoelectric plates.
