A flexible microrobots with magnetic actuation for medical tool

A flexible microrobots for medical tool to treat various vascular diseases have been developed for accurate manipulation. The proposed cylindrical microrobots were fabricated using a negative mold method by elastomer, Polydimethylsiloxane (PDMS), for deformability and flexibility. Steering of the fabricated microrobots were realized using 15 mT external magnetic field which is less than previously reported researches. Deflection angle of the microrobots is about 140 degree by the application of 160 degree of magnetic field direction with respect to the primary axis in initial state. This research is proposing a possibility of remotely controlled flexible microrobots for accurate manipulation under external magnetic field.
