MICROFLUIDIC DEVICE

摘要

A microfluidic device which is actuated by a piezo electric actuator. A microfluidic structure which comprises sequentially (i) a substrate through which there are a plurality of conduits (ii) a first layer of elastomeric material having a flat face and a patterned face having recesses formed therein, the flat face being bonded to the substrate and there being holes through the elastomeric layer connected to the recesses and aligned with the conduits in the substrate (iii) a second layer of a flexible material overlaying the patterned face of the elastomeric so that the holes and recesses in the elastomeric layer and the conduits in the substrate form channels through which fluid can flow (iv) an actuating means for driving a sealing means attached to or forming part of the second layer into at least one recess to modulate or seal the recess, which actuating means is operated by a piezo electric component.
