Abstract
A microfluidic control valve () comprising a dielectric structure () defining at least one cavity () therein. An electroactive material (), such as an electroactive polymer, is disposed in a portion of the cavity. The electroactive material is operable between a first state in which a dimension of the electroactive material has a first value and a second state in which the dimension has a second value. Two conductors () can be included for applying a voltage potential across the electroactive material to change the electroactive material between the first state and the second state. A first fluidic port () can be located proximate to the electroactive material such that a fluid flows through the first fluidic port when the electroactive material is in the first state, and the electroactive material at least partially blocks the first fluidic port when the electroactive material is in the second state.
