Abstract
Various methods and systems are provided for a multi-frequency transducer array. In one example, the transducer array includes an element formed of one or more sub-elements, at least one sub-element having a different resonance frequency. A frequency range of the transducer array may thereby be broadened.
Claims14
A transducer array, comprising:
- a plurality of piezoelectric elements, wherein at least some of the plurality of piezoelectric elements comprise a first sub-element and a second sub-element, wherein the first sub-element is a first piezoelectric material having a first resonant frequency and the second sub-element is a second piezoelectric material having a second resonant frequency that is different than the first resonant frequency, wherein the at least some of the plurality of piezoelectric elements include a first piezoelectric element and a second piezoelectric element, wherein the first piezoelectric element comprises a first relative proportion of the first piezoelectric material and the second piezoelectric material, wherein the second piezoelectric element comprises a second relative proportion of the first piezoelectric material and the second piezoelectric material, and wherein the first relative proportion is different as compared to the second relative proportion such that a relative proportion of the first piezoelectric material and the second piezoelectric material varies between the at least some of the plurality of piezoelectric elements.
