Abstract
A microfluidic valve operable to semi-permanently close a channel of a microfluidic device defined between a thermoplastic elastomer (TPE) film and a substrate operates employs a surface contact bond between the TPE and a wall of the channel. Thermomechanical release of the valve, tristate functionality, and repeated semi-permanent closure and release are demonstrated.
