Abstract
An exemplary system and method for providing an acoustic plate wave apparatus is disclosed as comprising inter alia: a monocrystalline silicon substrate ( ); an amorphous oxide material ( ); a monocrystalline perovskite oxide material ( ); a monocrystalline piezoelectric material ( ); and a flexural plate wave component ( ) having an input interdigitated transducer ( ), an output interdigitated transducer ( ) and an optional support layer ( ). Deposition or removal of material on or from an absorptive thin film sensor surface ( ), or changes in the mechanical properties of the thin film ( ) in contact with various chemical species, or changes in the electrical characteristics of a solvent solution exposed to the thin film ( ) generally operate to produce measurable perturbations in the vector quantities (e.g., velocity, etc.) and scalar quantities (e.g., attenuation, etc.) of the acoustic plate modes.
