The design and fabrication of electro-active polymers (EAP) actuators, in the form of active dimples is described. Active dimples alter the flow by creating time-dependent vorticity flux at the wall, by virtue of changes in surface pressure gradients and local surface accelerations. Potential elastomer films for the EAP dielectric are evaluated. It was found that elastomers could not be characterised using uniaxial testing. Instead biaxial testing, in the form of bulge tests, was carried out. Electro-mechanical tests are used to evaluate the dielectric breakdown strength and strain at different electric fields.
