L. Bay, K. West, P. Sommer-Larsen, S. Skaarup and M. Benslimane A Conducting Polymer Artificial Muscle with 12 % Linear Strain Advanced Materials 15
A soft polymer actuator has been constructed based on the volume change of a conducting polymer. The linear expansion (12 % at a load of 0.5 MPa) is the highest yet reported for a centimeter-scale conducting polymer actuator. This is achieved by controlling the structure on several length scales: Choice of molecular structure, synthesis from a structured medium, and forming the polymer actuator on a compliant, microstructured gold electrode.
