Abstract: A method for manufacturing a cylindrical dielectric elastomer actuator (DEA) is presented.
The cylindrical DEA can be used in fabricating the cuff area of dry-suits where the garment is
very tight and wearing the suit is difﬁcult. When electrically actuated, the DEA expands
radially and the suit can be worn more comfortably. In order to study the performance of the
DEA, a customized testing setup was designed, and silicone-made cuff samples with different
material stiffnesses were tested. Analytical and FEM modeling were considered to evaluate the
experimental output. The results revealed that although the stiffness of the DEA material has a
direct relationship with the radial constrictive pressure caused by mechanically stretching the
DEA, it has a minor effect on the actuation pressure. It was also found that stacking multiple
layers of the DEA to fabricate a laminated structure enabled the attainment of a desired
variation of pressure required for the implementation of an electrically tunable cuff.
