This research focuses on the design and experimental characterization of two types of asym- metrical MEMS electrothermal microactuators. Both MEMS polysilicon electrothermal microac- tuator designs use resistive (Joule) heating to generate thermal expansion and movement. Deflection and force measurements as a function of applied electrical power are presented.
