Linear artificial muscle actuator based on synthetic elastomer

Abstract

In this paper we present a new artificial muscle actuator for rectilinear motion made of synthetic elastomer, which is mainly focused on the robotic applications. Previously, we have developed a new material for actuating means, named "synthetic elastomer". Synthetic elastomer allows their material properties such as mechanical as well as electrical properties to be adjusted according to the requirements. Using the synthetic elastomers made of the recipe adjusted for the robotic application, a new design of the artificial muscle actuator, called multi stacked actuator is proposed. The actuator is comprised of multiple stacks of synthetic elastomer coated with compliant electrodes and connecting disks. This unique design enables its linear actuation with the large strain of active length as well as large force. Experimental works are conducted and the effectiveness of the actuator is validated.
