Abstract

Disclosed is a centrifugal microfluidic device comprising a piezoelectric substrate; a rotatable platform device on the substrate; and at least one transducer on the substrate, the transducer being configured to generate a surface acoustic wave that propagates on the surface of the substrate and contacts the rotatable platform device asymmetrically to transfer energy thereto with a lateral distribution to cause rotation of the rotatable platform device. The device may be a microfluidic valve, a microfluidic mixer or a microfluidic particle concentrator.
