The invention concerns a method whereby at least a predefined zone (A) of the object (2) is irradiated with a laser beam (4) capable of heating said zone sufficiently, to a temperature less than the material melting point, to provoke a change in the microstructure (for example crystallisation or recrystallisation) of said zone, said zone being heated at a temperature and for a time interval not rendering the material amorphous. The invention is applicable for example to reversible actuators and grippers.
