In this paper, a new material called synthetic elastomer, is presented as means of actuation. The material displays enhanced performances in terms of electrical as well as mechanical aspects such as dielectric constant, elastic strength and stress relaxation. We begin with developing synthesis procedures for the material, which results in its general recipe with chemical composition. In additio...

We report an equivalent circuit model for MEMS (microelectromechanical systems) electrostatic actuator using open-source circuit simulator Qucs (quite universal circuit simulator). Electrostatic force, equation of motion, and Kirchhoff’s laws are implemented by using the EDD (equation defined device) function of Qucs. Mathematic integral operation in the equation of motion is interpreted into e...

This study describes the design and testing of a dual-lane electric drive for a prototype, electromechanically actuated, nose wheel steering system for a commercial aircraft. The drive features two independent motor controllers, each operating onehalf of a dual three-phase motor, resulting in an actuator capable of full performance following an electrical fault. An isolated communications link ...

We present a study of an electrical model of electromechanically active carbon-polymer composite (CPC) with carbide-derived carbon (CDC) electrodes. The major focus is on investigation of surface electrode behavior upon external bending of the material. We show that electrical impedance measured from the surface of the CDC-based CPC can be used to determine the curvature of the material and, he...

Electrical actuators made from films of dielectric elastomers coated on both sides with stretchable electrodes may potentially be applied in microrobotics, tactile and haptic interfaces, as well as in adaptive optical elements. Such actuators with compliant electrodes are sensitive to the pull-in electromechanical instability, limiting operational voltages and attainable deformations. Electrode...

Exoskeleton is a type of wearable robots that can augment the performance of an able-bodied user. There are many studies that use hydraulic actuator to actuate the lower limb exoskeleton which possesses several drawbacks like dirty, noisy and high power consumption. Therefore, electrical actuators that are clean, silent and less power consuming are used in designing the lower limb exoskeleton i...

The objective of current paper is 3D simulation of turbulent, developing flow and unsteady within a circular duct in presence of the body force vector persuaded by Dielectric barrier discharge (DBD) plasma actuator inside the surface of geometry for the first time. This article aims at investigating of applying plasma actuator to control separation with special arrangement of electrodes. For th...
