Background: Electrothermal microactuators are very promising for wide range of Microelectromechanical Systems (MEMS) applications due to the low voltage requirement and large force produced.
Method: A new optimized V-beam electrothermal micro actuator was implemented in variable optical attenuator. In this work, Particle Swarm Optimization (PSO) technique is proposed to design the Vshaped beam.
Result: The approach has successfully improved both angular displacement & output force of the microactuator. Entropy generation rate was used as optimization criteria.
