Abstract
This invention provides a transducer for generating ultrasound waves to detect objects and an ultrasound probe using the same. The transducer includes a piezoelectric layer. The piezoelectric layer has opposing first and second surfaces. The first surface includes a curved structure. The first surface is farther from the object than the second surface. The curved structure protrudes along a first direction away from the object. The ultrasound probe includes a handheld component and the transducer. The transducer is disposed at one end of the handheld component.
