Abstract

Provided are a method for preparing a microfluidic device, a microfluidic device and a microfluidic system. The method includes: providing a mold having a groove; injecting a liquid metal into the groove of the mold, and solidifying the liquid metal to obtain a solid metal; separating the solid metal from the mold; providing the solid metal with an electrode; providing a cladding layer on a surface of the solid metal provided with the electrode, such that the solid metal is wrapped by the cladding layer, and at least a part of the electrode extends outside the cladding layer, so as to obtain a preform; and fixing the preform in a substrate, melting the solid metal and extending at least a part of the electrode outside the substrate, to obtain the microfluidic device.
