Abstract:The mechanism of force generation in a polymer monofilament actuator element with auxetic characteristics is modeled to assess the development and the optimization of a controlled drive based on the use of electrostrictive polymers. The monofilament is considered as a viscoelastic rod. By assuming a 'sliding thread' deformation occurring within the system, the variation of the monofilament length during the uniform contraction and force generated during a uniaxial mode of actuation have been obtained. The dist… Show more
