Title:
MICROFLUIDIC DEVICE AND PREPARATION METHOD THEREFOR, AND MICROFLUIDIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/010788
Kind Code:
A1
Abstract:
A microfluidic device and a preparation method therefor, and a microfluidic system. The preparation method comprises: S1, providing a mold having a groove; S2, injecting a liquid metal into the groove, and solidifying the liquid metal to obtain a solid metal; S3, separating the solid metal from the mold, and providing an electrode on the solid metal; S4, forming a coating layer on a surface of the solid metal having the electrode, so that the solid metal is wrapped in the coating layer, and the electrode at least partially protruding out of the coating layer, so as to obtain a prefabricated device; and S5, placing the prefabricated device in a substrate, melting the solid metal and making the electrode at least partially protrude out of the substrate, so as to obtain a microfluidic device (a). The preparation method is simple, the packaging has good performance, the device is highly integrated and is easy for industrialization, the microfluidic device obtained by means of this preparation method is good in molding, excellent in performance, can be widely used, and can be integrated with a power supply, a signal transmitter and a signal receiver to form a microfluidic system.
