Microactuators　that　convert　external　stimuli　such　as　heat,　light,　current,　and　magnetic　field　into　mechanical　motion　are　essential　components　in　microelectro-mechanical　systems.　To　date,　microactuators　have　been　fabricated　mainly　using　conventional　microfabrication　technologies　and　inorganic　thin　films,　but　although　such　technologies　facilitate　the　mass　production　of　microdevices,　they　are　expensive　and　lack　flexibility　when　either　preparing　only　a　few　devices　or　facing　special　needs.　Laser-direct-writing　is　an　effective　complement　to　microfabrication,　but　is　seldom　used　in　the　construction　of　inorganic　microactuators.　In　this　work,　a　laser-direct-writing　technique　on　the　freestanding　vanadium　dioxide　(VO2)　film　for　fabricating　microactuators　with　arbitrary　shapes　is　developed.　The　precision　of　the　laser　direct　writing　attained　2　mu　m　under　ultralow　pulse　energy　of　52　pJ.　The　pulse　energy　is　two　orders　of　magnitude　lower　than　that　needed　for　patterning　VO2　film　and　other　semiconductor　materials　on　substrates.　The　overall　performance　of　the　resulting　VO2　microactuators　is　comparable　with　that　of　those　fabricated　by　conventional　microfabrication　technologies,　but　the　fabricating　efficiency　and　flexibility　are　increased.　Such　a　fabrication　strategy　can　also　be　used　to　fabricate　other　smart　microdevices,　such　as　strain　sensors　and　photodetectors.
