Towards array micromanipulators based on dielectric elastomers
Original language description
The paper describes the authors' initial steps in the domain of advanced microactuators based on dielectric elastomers. Namely, local deformation of a thin (~10um) elastomer film as a result of Maxwell pressure on the surface is analyzed. The pressure results from attractive forces between the opposite charges on the conducting electrodes deposited on both sides of the polymer film. When at least one of the two electrodes is compliant, repulsive forces among the alike charges also contribute to the surface deformation. Compared to the conventional materials such as piezoelectric ceramics, DEA promise much higher strain (nearly 10%) while keeping reasonable values of other parameters such as efficiency and time response. The ultimate goal of this initiating research is to develop a deformable surface that could be used for planar manipulation with flat objects placed on top of it.
