▎ 摘　　要

NOVELTY - The device has a temperature control system provided with an electric contact sensor. A temperature control circuit is embedded in a top polydimethylsiloxane (PDMS) structure (3). An outlet of the top PDMS structure is connected with an outlet conduit (6). A porous medium thin layer is placed in a bottom layer microfluidic channel. A graphene thin layer structure is placed on a top microfluideic channel (5-4). A thermistor is located at a center of the porous graphene. The temperature control circuits are embedded in the top PDMS structure. A controllable direct current (DC) voltage stabilizing source provides stable DC working voltage. A double-layer microfluidic chip and micro-flow control device are provided. The double-layer microfluidic chip comprises a glass slide (1), a bottom PDMS structure (2), top PDMS structure, an inlet conduit (4), a double-layer microfluidic channel(5) and an outlet conduit. USE - The simulation device is used for complex micro-flow environment. ADVANTAGE - The device accurately simulates the in-vivo environment and accurately measures the flow rate of the micro-scale flow without contact. The device has high conductivity, high light transmittance, and high stability of the ultra-thin graphene to micro-flow control with uniform and stable temperature control, generates non-toxic, transparent, and stable sucrose solution, and realizes movement visualization of the nanoparticles in porous medium thin layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a measuring method of complex micro-flow rate. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of simulation device.
