Paper Title:
Fabrication of Piezoelectric Thickness-Shear-Mode Acoustic Wave Sensing Device and its Application
  Abstract

The piezoelectric thickness-shear-mode (TSM) acoustic wave sensing device was fabricated by coating with a calixarene derivative on the surface of gold electrode of quartz crystal, then connecting with a transistor-transistor-logic (TTL) oscillator, a frequency counter and a computer. Among four coating materials, the compound of calixarene I was the most efficient active material for adsorption of carbinol molecule based on a host-guest recognition mechanism. In comparison with gas chromatography (GC) method, the calixarene based TSM device can be used for on-line determination of the poisonous carbinol vapor in the range of 0 ~ 3000 ppm around our living environment with good selectivity, reproducibility and high stability. The detection limit can be evaluated to be 1.41 ppm.
