There exists a need for dependable, rapid, high performance                     microsensors capable of performing in a liquid environment and capable          of detecting change in liquid properties such as density, viscosity             and change in molecular composition.  Microwave acoustic wave                   technology offers one of the most attractive methods to realize these           types of microsensors.  Shear horizontal type waves excited by                  interdigital transducers (IDT) such as the Bleustein-Gulyaev (BG)               wave, or the surface skimming bulk wave (SSBW) or plate modes appear            suitable for liquid sensor applications.                                                                                                                        This research will include in-depth theoretical and experimental                studies of acoustic wave liquid-phase-based chemical sensors.  The              analysis will provide design equations to realize a new class of                inexpensive, sensitive and rapid detectors.  Prototype sensors will be          implemented with or without selective, sensitivity enhancement film             coatings.  The various chemical systems which will be studied include           crystals (C-6 and C-12 sugars, polysaccharides) dissolved in aqueous            solution, ligand with metal ion, dilute concentration of metal and              acid/base titration.  A complete evaluation of the sensor                       effectiveness such as detection limits, sensitivity, reproducibility            and response time will be made.
