- Abstract
- An electroacoustic chemical sensor based on thin-film bulk acoustic wave resonators ?TFBAR? is
presented. It operates on the same principle of the well-known quartz crystal micro-balance, at an
operation frequency extended up to several GHz. The larger output signal, associated to the higher
operation frequency, is a condition to improve the device sensitivity. TFBARs have been
implemented on ?001? Si wafers, using Si3N4 /AlN membranes, obtained by anisotropic etching of
Si. Time response and calibration curves have been tested on TFBAR sensors exploiting two
different chemically interactive membranes: Pd and Co-tetra-phenyl-porphyrin, both deposited in
the form of thin-films by thermal evaporation. Measurements performed upon exposure to H2, CO,
and ethanol have shown the ability of the device to detect low concentrations of the analyte with a
fast and repeatable response (literal)
