Abstract
Piezoelectric Micromachined Ultrasound Transducer (pMUT) arrays for ultrasonic imaging, and related apparatuses, systems, and methods are disclosed. In one embodiment, an ultrasonic imaging assembly comprises a substrate and a plurality of array elements arranged on the substrate in an array. Each array element comprises at least one pMUT disposed on the substrate each having a geometry configured to accept a predetermined fundamental mode vibration. The plurality of array elements are configured to transmit and receive at least one ultrasound beam based on the predetermined fundamental mode vibration. By sizing the pMUTs to correspond to a desired fundamental mode vibration, the pMUT array has improved sensitivity, and can be produced relatively cheaply compared to conventional dicing methods.
