9909214There is a tremendous growth in technologies associated with microdevices usingactive polymers for microfluidics and microrobotics applications. This SGERproject uses a coupled experimental and analytical approach to provide theconstitutive descriptions necessary for systematic design using compliant activematerials. A novel Biaxial System for Active Materials (BSAM) is being developedto measure the finite deformations of thin films of such materials, includinghyperelastic and viscoelastic behavior and active response under mechanicalload, by measuring local deformation and applied force histories whilecontrolling the trajectory in stretch space. Criscione invariants will be usedto characterize the hyperelastic potentials.
