    摘要： Components, such as a cutting element for an earth-boring drilling tool include an ultrasonic transducer coupled therewith, and configured to transmit an acoustic signal therethrough, and transmit a data signal to a data acquisition unit in response to receiving a returning echo of the acoustic signals. An earth-boring drilling tool, comprises a bit body including a plurality of components, an ultrasonic transducer, and a data acquisition unit operably coupled with the ultrasonic transducer. The data acquisition unit may be configured to receive the data signal and determine a temperature distribution of the component based, at least in part, on a time-of-flight of the acoustic signals and the returning echoes. Methods for forming such components and measuring a temperature of such components may relate to coupling and implementing such an ultrasonic transducer with a component of an earth-boring drilling tool.
