Abstract: A method for obtaining one or more free-form individual fibers of biocompatible hydrogels with a predefined diameter, wherein said method comprises the use of a printing system comprising at least a first nozzle (110) and a second nozzle (120) surrounding the first nozzle, wherein said method comprises the following steps: a) providing a printable biocompatible hydrogel (130) in the first nozzle; b) providing a printable composition (140) comprising a non-toxic thermoreversible gelation polymer in the second nozzle; c) extruding the biocompatible hydrogel in a) and the composition in b) simultaneously through the nozzles, wherein the composition in b) in a gel state coats the extruded biocompatible hydrogel; d) optionally, submitting the obtained one or more individual fibers to a cross- linking treatment; e) optionally, removing the composition in b) from the external surface of the deposited one or more fibers.

Abstract: A microrobot is disclosed. The microrobot includes a magnet configured to provide a motive force when magnetic force of one or more electrical coils act upon the magnet, a support member coupled to the magnet, a thermo-responsive polymer member coupled to each end of the support member at a proximal end, the thermo-responsive polymer member configured to articulate when heated, wherein the thermo-responsive polymer members configured to receive light from a microrobot structured light system and convert the received light into heat.
