In order to improve the performances of microfluidic actuators, a microfluidic actuating way based on the shape memory alloy(SMA) is presented, which is applied for the liquids circulation of a microfluidic colour-changing system. A SMA spring is used as the main actuating part, a microfluidic actuating device based on the SMA spring is designed and fabricated. The models for the SMA spring and the whole SMA actuated microfluidic system are established, the experimental platform is built. The temperature properties, output displacement performances and pressure responses of the present system are simulated and tested under different experimental conditions. Comparing with traditional microfluidic actuating systems, the SMA actuated microfluidic colour-changing system is driven by using DC power, small in size, convenient in operation, and has fast response speed and high reliability.
Key words: shape memory alloy / microfluidic actuating / microfluidic colour-changing system
