Abstract
This paper presents a novel vacuum transformer with battery-powered mini-hotplates for two-stage liquid driving for simple-to-use microfluidic biochips. Hie conception of the research is completely different from current traditional design, it could decrease the complexity of systematic design and procedure with smart polymer materials, it stylizes for memorizing the switch of two different geometric patterns in advance while synthesizing the material so as to complete the transformation. Experimental measurements show that the fluiclic (Li-transfomer with an effective cavity volume of 80 |il can achieve -4.7 psi differential pressure. The developed novel systems could provide the same delivery function with the traditional vacuum pumps for disposable simple-to-use microfluidic biochips.
