Latchable microfluidic valve arrays based on shape memory polymer actuators

Herbert Shea, Nadine Besse, Bekir Aksoy

We report arrays of latching microfluidic valves based on shape memory polymers (SMPs), and show their applications as reagent mixers and as peristaltic pumps. The valve design takes advantage of the SMP's multiple stable shapes and over a hundred-fold sti ...
