Abstract
A microfluidic valve structure is provided. The valve structure includes a valve body having a fluid flow passage formed therein for allowing fluid to flow therethrough. A valve boss is configured to move relative to a valve seat to open and close the fluid flow passage. A plurality of flexible support arms extend between a wall of the valve body and the valve boss for supporting the valve boss relative to the valve body such that the valve boss engages and disengages the valve seat to close and open the passage.
