Abstract
A study has been performed for the development of elastic-waves struct ures, involving screen printed and fired piezoelectric layers on nonpi ezoelectric substrates, intended for new families of thick film sensor s. This study approached the electroacoustic effects, i.e., the coupli ng between electromechanical. parameters of the layers and elastic pro perties of the substrate, related to the wave propagation. In this wor k, particular attention is devoted to devices implemented on alumina s ubstrates where SAW as well as (symmetric and antisymmetric) Lamb's wa ves are generated. The realization processes and the performance chara cteristics of these structures are presented.
