An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. [1] An actuator translates such an input signal into the required form of mechanical energy.
The aim of high redundancy actuation is not to produce man-made muscles, but to use the same principle of cooperation in technical actuators to provide intrinsic fault tolerance. To achieve this, a high number of small actuator elements are assembled in parallel and in series to form one actuator (see Series and parallel circuits).
Such self-powered schemes are particularly beneficial in development of self-powered sensors [10] and self-powered actuators [11] by employing energy harvesting techniques, [12] [13] [14] where kinetic energy is converted to electrical energy through piezoelectric, electromagnetic or electrostatic electromechanical mechanisms.

A plasma actuator induces a local flow speed perturbation, which will be developed downstream to a vortex sheet. As a result, plasma actuators can behave as vortex generators. The difference between this and traditional vortex generation is that there are no mechanical moving parts or any drilling holes on aerodynamic surfaces, demonstrating an ...
C) Traditional (linear) geometry plasma actuator. D-F) Additional serpentine plasma actuator geometries. The serpentine plasma actuator represents a broad class of plasma actuator. The actuators vary from the standard type in that their electrode geometry has been modified in to be periodic across its span. [1] [2]
The WEAV employed serpentine geometry plasma actuators for fully three-dimensional flow control which combine the effects of a linear actuator and plasma synthetic jet. [ 15 ] [ 16 ] [ 17 ] Due to the periodic geometry of the serpentine design, there is pinching and spreading of the surrounding air along the actuator. [ 18 ]
