Technical Paper


Comb drive actuators are very important microelectromechanical systems structures that are widely used in many applications. They are currently used in force balanced accelerometers, resonant accelerometers and resonant gyroscopes, micro-grippers and micro-engines. In addition, they are extensively used in opto-mechanical subsystems such as switches and variable optical attenuators. The goal of this paper is to present a comb drive actuator model design with ultra-low pull-in voltage to achieve large displacement, deriving the exerted forces equations, mechanical analysis and the most important problems, also comparing with the previous work done to treat these problems.
