Abstract
A sensing system utilizes a channel, a BAW resonator structure including piezoelectric material with a c-axis having an inclined orientation, at least one functionalization material arranged over an active region of the BAW resonator structure, and a driving circuit configured to apply AC signals at different frequencies to cause the piezoelectric material to selectively exhibit a dominant shear response or a dominant longitudinal response. Driving the piezoelectric material in longitudinal mode induces localized fluid mixing proximate to the active region, whereas driving in shear mode permits detection of analyte bound to the at least one functionalization material in a liquid environment. Recesses may be defined in a surface of a top side electrode to enhance longitudinal mode mixing.
