Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] The microfluidic device based on the phased array ultrasonic transducer in the present invention includes a frame body 2, a phased array ultrasonic transducer 1, a funnel 3 and a lifting assembly, see figure 1 , the funnel 3 is filled with fluid.
[0033] The phased array ultrasonic transducer 1 is provided with a plurality of ultrasonic sending / receiving elements 11, and the ultrasonic sending / receiving elements 11 are arranged in an array. The phased array ultrasonic transducer 1 includes a plate body 12, and the plate body 12 is a concave structure. A plurality of ultrasonic sending / receiving elements 11 are arranged in an array on one side of the concave surface of the plate body 12, see figure 2 , while making the concave side of the plate body 12 face the wide mouth side of the funnel. In this way, the fluid in the funnel is ...
