Theme 2.1: Nanostructured Actuators - First Principles Prediction to Fabrication
The overall goal of Theme 2.1 is to develop a lightweight polymer actuator exhibiting high power density, large and fast contraction capabilities and high strength. This actuator technology is at the center of the design of a multifunctional Soldier armored actuation system protecting and enhancing the performance of the Soldier in the battlefield. Our aim is to design, model, synthesize and study novel polymer nanoscopic architectures to produce these actuators with superior performance relative to non-structured bulk actuator materials. These novel materials are based upon a combination of ground-breaking conducting polymer molecular architectures (Swager Laboratory), innovative processing and manufacturing techniques (Thomas and Hunter Groups), advanced quantum mechanical modeling (Marzari Group) and novel development of instruments for extended actuator characterization (Hunter Group). Previously, within the framework of the ISN supported project we have successfully created active materials generating 100 times more force per unit cross section than human skeletal muscle. Making use of our pioneering work and unusual approach from first principles modeling to fabrication, our ambitious yet achievable objectives within this theme are to create enabling contractile materials for an active battle suit within 3 years.
