A Proportionally Controlled Microvalve using a Piezoelectric Unimorph Microactuator

Microvalves are important flow-control devices in many standalone and integrated microfluidic applications. PDMS-based (Polydimethylsiloxane) pneumatic microvalves are the most commonly used type for research purposes, but they require large peripheral connections and cannot be used for controlling gases due to the high gas permeability of PDMS....

Conducting Polymer Microfluidic Valve

Microfluidics has changed the way we think about laboratory experimental design. With the use of lab-on-chip devices, we are capable of carrying out experiments that include several functions on a single chip. Despite a lot of progress in the miniaturization of these devices, the peripheral systems which control the microfluidic functionalities...
