One of the major needs for the successful miniaturization of microfluidic systems is the integration of portable, low-voltage, low-power microvalves to manipulate the fluid flow through a network of microchannels. We report here a low-power, thermally actuated, elastomer-based microvalve with thermal isolation, which is then integrated in a thermoplastic microfluidic device. In the 6-layer design...
We report using polyurethane (PU) as an elastomer in microvalves integrated with thermoplastic microfluidic devices. Elastomer‐based microvalves have been used in a number of applications and the elastomer often used is PDMS. Although it is a convenient material for prototyping, PDMS has been recognized to possess shortcomings such as solvent incompatibility and unfavorable manufacturability. We investigated...
