A multilayer transducer that contains piezoelectric layers
Source abstract
Abstract
Formulas for the transfer functions and electric resistance for transducers that consist of an arbitrary number of active (piezoelectric) and passive layers are obtained. Parallel and series electrical connections of layers are considered. Formulas for reducing any active layer to a passive one are obtained. On the basis of the analysis of the obtained expressions and presented calculation results, recommendations for the practical use of the considered transducers are expounded. The obtained data allow the development of transducers with appreciably improved characteristics in comparison to the case where only one active element is used. The proposed new calculation method makes it possible to substantially simplify the determination of formulas for an arbitrary number of layers. The formulas for the main functions of a transducer concern multiple three-sided transducers, on one side of which certain conditions for their electrical connection are imposed. The transfer functions for the reception mode with respect to the voltage at the working surface of the transducer are obtained. The proposed calculation method can be also applied to other types of transducers.
