Abstract: An electronic device including an array of ultrasonic transducers, a temperature sensor for determining a temperature of the array of ultrasonic transducers, and a control module communicatively coupled to the array of ultrasonic devices and the temperature sensor. The control module is for receiving the temperature and for controlling operation of the array of ultrasonic transducers based at least in part on the temperature.

Abstract: An ultrasonic transducer array, and a method for manufacturing it, having a plurality of transducer elements aligned along an array axis in an imaging plane. Each transducer element includes a piezoelectric layer and one or more acoustic matching layers. The piezoelectric layer has a concave front surface overlayed by a front electrode and a rear surface overlayed by a rear electrode. The shape of each transducer element is selected such that it is mechanically focused into the imaging plane. A backing support holds the plurality of transducer elements in a predetermined relationship along the array axis such that each element is mechanically focused in the imaging plane.
Abstract translation: 一种超声换能器阵列及其制造方法，具有沿成像平面中的阵列轴排列的多个换能器元件。 每个换能器元件包括压电层和一个或多个声匹配层。 压电层具有由前电极覆盖的凹前表面和由后电极覆盖的后表面。 选择每个换能器元件的形状使得其被机械地聚焦到成像平面中。 背衬支撑件沿着阵列轴将多个换能器元件保持在预定关系中，使得每个元件在成像平面中被机械地聚焦。
