Self-healing material could be a breakthrough for humanoid robots


Researchers at US university Carnegie Mellon have created a new electrically conductive material that can repair itself, presenting new opportunities for soft robotics and wearable technology. Combining properties of metal and plastic, the supple, stretchy material can be used to make circuits that stay operational even after sustaining physical damage. The discovery opens up the possibility that robots may one day have sensor-laden skin that can repair itself like a human's, or that we could sport ultra-thin wearable devices on our bodies for long periods of time without them degrading. "This could have important applications in areas like wearable computing, where you want circuits you can incorporate into textiles or place on your skin, and just like natural skin if you get bruised or cut, your skin is able to repair itself," says Carmel Majidi, an associate professor of mechanical engineering, in a video produced by Carnegie Mellon University (CMU). "Our material also has this property."
