- ABSTRACT
- The demand for actuators featuring biomimetic properties, such as direct drive, high power density and compliance, is growing in robotics and bioengineering. Our work is dedicated to increasing the performance of these actuators, utilizing active polymer components which are characterized in several different electrical stimulation conditions. In order to increase the strain of the system, we have considered a configuration inspired by McKibbens muscle. In this solution, each active element is covered by a braid mesh shell (with flexible but not extensible threads), which contracts when the element increases its volume. This technological solution amplifies the strain up to 10 times, and can be utilized to reach tangible shortening of the actuator.
