Abstract
This paper reports a selective wireless active valve mechanism for a centrifugal microfluidic compact disk operated using field frequency modulation techniques. The reported technique offers a further advancement in the centrifugal microfluidic field by enabling full control on the liquid flow. The localized and selective RF wireless heating of paraffin wax active valves was utilized to control the liquid flow in centrifugal CD. Vacuum/compression valve (VCV) and mixing applications are also demonstrated in this work. Experimental characterization shows valve operational is within ~100 s of activation using a radio frequency power of 1 W, at a speed of 200 rpm. The reported technique offers a further advancement in the centrifugal microfluidic area by enabling full control on liquid flow.
