Abstract
An ultrasonic transducer detector having a high operating frequency is provided. The ultrasonic transducer detector comprises a substrate and an ultrasonic transducer array. The substrate has a plurality of openings, and the ultrasonic transducer array is disposed on the substrate. The ultrasonic transducer array has a plurality of resonance units, and the thickness of each resonance unit is equivalent to ½ wavelength of the operating frequency of the ultrasonic transducer. Each resonance unit comprises an oscillating element and a piezoelectric element. The oscillating element has a first surface adjacent to the substrate, and the piezoelectric element is disposed on the first surface and located in the corresponding opening.
