Abstract: The present application relates to an ultrasound temperature mapping system and method. The ultrasound temperature mapping system for measuring a temperature of an object comprises an ultrasound transducer and a processing module. The ultrasound transducer is configured to acquire a first image and a second image with respect to the object. The processing module implements a zero-crossing algorithm to process the first image to yield a plurality of first zero-crossing points and implements a cross-correlation algorithm to process the first image and the second images based on the plurality of first zero-crossing points so as to obtain a plurality of displacements. The processing module further calculates the temperature based on the plurality of displacements.

Abstract: An ultrasonic sensor includes a casing body and a piezoelectric element. The casing body has a base wall and a surrounding wall that cooperates with the base wall to define an interior space. The base wall has a top surface and a bottom surface. The top surface has a first section, a second section that extends between the first section and the surrounding wall, and a connecting section interconnecting the first and second sections. A distance between the second section and the bottom surface is larger than that between the first section and the bottom surface such that the connecting section and the first section cooperate to define a recess. The piezoelectric element is confined in the recess.

Abstract: The method of changing ultrasound wave frequency by using the acoustic matching layer presents a replaceable acoustic matching layer to offer an effective means of filtering the original broadband frequency of an ultrasonic transducer into certain composite discontinuous frequencies. The filtering effect could be improved by connecting the electrodes of the acoustic matching layer when it is made of a poled piezoelectric material. This method may provide novel applications for commercial ultrasonic transducers.

Abstract: An ultrasound transducer has a cup-shaped casing. The cup-shaped casing has a sidewall. A cross section of an inner surface of the sidewall being perpendicular to a central axis of the ultrasound transducer substantially shows a dumbbell-shaped contour. The dumbbell-shaped contour has a pair of opposite straight-line sections being substantially parallel to a longitudinal axis of the dumbbell-shaped contour and a pair of opposite arc sections being located respectively at two ends of the longitudinal axis of the dumbbell-shaped contour and respectively forming two enlarged portions of the dumbbell-shaped contour. Two ends of each arc section of the dumbbell-shaped contour respectively joint the straight-line sections through two curve sections and each curve section is connected to one end of the arc section and one straight-line section. At least one enlarged area of a dumbbell-shaped surface of an inside bottom surface has a recessed portion.
