Abstract
A detection system includes a central manifold including a detection chamber, a pipe network including at least one pipe fluidly coupled to the central manifold, a plurality of inlets formed over a length of the at least one pipe and an aspirating mechanism operable to draw a fluid flow at each of the plurality of inlets through the pipe network to the central manifold. A plurality of independently operable flow control devices is associated with the plurality of inlets. At least one of the plurality of flow control devices includes a solid state flexible polymer deformable in response to application of a voltage.
