Electrostatic Actuators with Intrinsic Stress Gradient II. Performance and Modeling
Electrostatic actuators are used as voltage-controlled oscillators or resonators in high frequency applications. The change in deflection of a cantilever beam due to an applied voltage leads to change in capacitance between the plates of the beam. However, the range of operation of these devices is limited due to the nonlinear nature of the applied electrostatic forces as the cantilever beam mo...
متن کاملFeasibility study on self-healing compliant actuators
Natural organisms have a unique property not yet available in robotics, a self-healing (SH) ability. This powerful biological healing function has inspired chemists to impart similar properties to synthetic materials to create “self-healing materials”. Recent development in SH-polymers made us investigate the potential of using these materials in robotics, and more specifically in compliant act...
متن کاملStability Analysis in Parametrically Excited Electrostatic Torsional Micro-actuators
This paper addresses the static and dynamic stabilities of a parametrically excited torsional micro-actuator. The system is composed of a rectangular micro-mirror symmetrically suspended between two electrodes and acted upon by a steady (dc ) while simultaneously superimposed to an (ac ) voltage. First, the stability of the system subjected to a quasi-statically applied (dc ) voltage is investi...
متن کاملMuscle-like Actuators? a Comparison between Three Electroactive Polymers
Muscles fulfill several functions within an animal’s body. During locomotion they propel and control the limbs in unstructured environments. Therefore, the functional workspace of muscle needs to be represented by variables describing energy management (i.e. power output, efficiency) as well as control aspects (i.e. stiffness, damping). Muscles in the animal kingdom vary greatly with respect to...
متن کاملMuscle-like Pneumatic Actuators for Below-knee Prostheses
This paper reports on the design of a biorobotic actuator intended for use in a powered, below-knee prosthesis. Design requirements for the artificial muscle and tendon are based on the properties of the natural limb. As biological properties often exhibit significant variability, data from a variety of vertebrate species are extracted from published reports in the biological literature and use...
