  • Patent number: 10780437
    Abstract: Disclosed is a microfluidic system based on an artificially structured acoustic field, comprising a microcavity used to accommodate a solution containing particles and a ultrasonic emission device used to emit ultrasound, and further comprising a phononic crystal plate placed in the microcavity. The phononic crystal plate has an artificial cycle structure, and is used to modulate the acoustic field so as to control the particles. Also disclosed is a method of controlling microfluid particles based on an artificially structured acoustic field. In the particular embodiments, since a microcavity, an ultrasonic emission device and a phononic crystal plate are comprised, the ultrasonic emission device is used to emit ultrasound, and the phononic crystal plate has an artificial cycle structure, and is used to modulate the acoustic field so as to control the particles.

  • Publication number: 20200187907
    Abstract: Provided is an ultrasonic transducer and a preparation method thereof. The ultrasonic transducer includes a housing. A piezoelectric layer is disposed in the housing and includes at least two piezoelectric array elements. A frequency interval between the piezoelectric array elements is 50 kHz to 1.2 MHz. An acoustic lens is disposed at a front end of the piezoelectric layer and is used for ensuring that the piezoelectric array elements having different frequencies have a common focus.

  • Publication number: 20190053786
    Abstract: A delayed excitation ultrasonic imaging method includes: generating a regulating clock, and performing, according to the regulating clock, delayed excitation on an ultrasonic transducer once or multiple times; performing data collection on an ultrasonic echo signal of the ultrasonic transducer and signals after each time of performing delayed excitation; synthesizing and superimposing data collected to obtain high sampling rate data; and performing ultrasonic imaging according to the high sampling rate data. A delayed excitation ultrasonic imaging apparatus and system are also provided. By performing delayed excitation on the ultrasonic transducer, the high-frequency ultrasonic imaging is realized by low-frequency sampling and delayed excitation, which can greatly reduce the cost of the ultrasonic imaging system.
