Tech Watch: Liquid Robots and Self-repairing Metals (Increase in Knowledge/New Technologies) PDF Print E-mail
Robots flexible enough to squeeze through tiny cracks, and metals that can fix their own bends or dents are both on the horizon, according to recent research studies and proposals. Both technologies rely on metallic compounds with "memory" for past shapes. These metals may be as strong and flexible as other alloys, but display the unique ability to flip back to their original form given a stimulus such as electric current. Self-repairing metals are already a reality, at least in the laboratory. Researchers at the University of Illinois describe a method for producing these specialized substances in the online edition of the journal Science.
