Abstract: A micro-actuator includes a shape memory thin film having one end fixed to a substrate and one remaining part which, at room temperature, is in the martensitic phase and assumes a curly-configuration, whereas at a higher temperature than a threshold value it changes to the austenitic condition, wherein the film is completely stretched upon the substrate.
