The use of dielectric elastomer (DE) for the realisation of new generation actuators has attracted the interest of many
researchers in the last ten years due to their high efficiency, a very good electromechanical coupling and large achievable
strains [1-3]. Although these properties constitute a very important advantage, the industrial exploitation of such systems
is hindered by the high voltages required for the actuation [4] that could potentially constitute also a risk for the
operators.
In this work we present a DE based active layer that can be used in different macro-scaled parts of industrial equipment
for roto-flexographic printing substituting traditional mechanical devices, reducing manufacturing costs and enhancing
its reliability. Moreover, the specific configuration of the system requires the driving voltage to be applied only in the
mounting/dismounting step thus lowering further the operative costs without posing any threat for the workers.
Starting from the industrial requirements, a complete thermo-mechanical characterisation using DSC and DMA was
undertaken on acrylic elastomer films in order to investigate their behaviour under the operative frequencies and
solicitations. Validation of the active layer was experimentally evaluated by manufacturing a DE actuator controlling
both prestrain and nature of the complaint electrodes, and measuring the electrically induced Maxwell’s strain using a
laser vibrometer to evaluate the relative displacement along the z-axis.
