Soft Robotics
Magnetically actuated soft robots may improve the treatment of disseminated intravascular coagulation. They also have applications in eye and brain surgery. Significant progress has been made in the development of soft robotic systems that steer catheters and guide wires. The fabrication and modeling of these new generation of robots have been studied in recent works. The soft robots are attached to the tip of the guidewire, and are magnetically steered by changing the direction and intensity of an external magnetic field. 2D and 3D steering of the devices are studied. My main research objectives is to make practical miniature soft robots for surgical interventions.
