Abstract

The effect of a dielectric weight load on the zero-order acoustic modes in a thin piezoelectric plate of lithium tantalate (LiTaO3) was theoretically studied, and the change in this sensitivity in the presence of a liquid was estimated. The gravimetric sensitivity has a complicated frequency spectrum and also depends on the plate thickness and on the load material. The presence of a liquid can significantly increase the sensitivity of zero-order acoustic modes in a piezoelectric plate with respect to a dielectric weight load.
