Abstract
The present disclosure provides a transducer for generating ultrasonic waves to detect an object and an ultrasonic probe using the same. The transducer includes a piezoelectric layer. The piezoelectric layer has a first surface and a second surface opposite to the first surface. The first surface is farther from the object than the second surface and includes a curved structure protruded along a first direction away from the object. The ultrasonic probe includes a handle component and a transducer. The transducer is arranged at one end of the handle component.
