The invention discloses an ultrasonic transducer probe. The ultrasonic transducer probe includes a plurality of stacked ultrasonic transducer probe units; the ultrasonic transducer probe unit includes a piezoelectric material block, a first electrode and a second electrode. Electrodes; the first electrode and the second electrode are arranged on the surface of the piezoelectric material block and there is an insulating isolation area between them; the same electrodes of the adjacent ultrasonic transducer probe units are electrically connected The isolated areas on the contacting surfaces of the adjacent ultrasonic transducer probe units partially overlap or completely overlap, so that the electrodes on both sides of the overlapped isolated areas are not electrically connected, and the ultrasonic transducer probe ultrasonic transducer The ultrasonic transducer probe of the probe includes the ultrasonic transducer probe unit of the piezoelectric material blocks with different thicknesses, which can increase the adjustment range of the electrical impedance of the device on the premise of low cost. The present invention also simultaneously provides an ultrasonic imager with the above beneficial effects.
Description
Technical field [0001] The present invention relates to the field of energy conversion techniques, and more particularly to an ultrasonic transducer probe and an ultrasound imager. Background technique [0002] The ultrasonic imager is used as a transformation device that implements electrical energy and acoustic energy, except that the device itself needs excellent acoustic and electrical properties, the transducer and the ultrasound imaging system circuit of the ultrasound imaging system are matched, and It also affects the power size obtained from the ultrasound imager in the transducer itself. Therefore, in the transducer design, the electrical impedance of the device is as high as the electrical impedance of the ultrasonic imaging system circuit of the ultrasound imager as possible. [0003] If you want to change the electrical impedance of the device, it is generally considering from the material of the device. By changing the resistance of the device of the device, the ele...
