Most conventional androids are fairly rigid, susceptible to damage and difficult to repair. However, scientists are determined to (literally) give them thicker skins. They've experimented with soft, deformable circuits that are flexible, and could reduce business expenses in the long term -- but are still prone to tearing and puncturing. The solution to these issues may lie in one recent advancement. A group of researchers from Carnegie Mellon University have found a way to counter surface damage and electrical failure commonly observed in soft materials used in engineering robotic electronics.
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."
If there's one thing that scientists absolutely should be working on, it's a self-regenerating robo-Deadpool or the eerily-fluid T-1000 Terminator. Thankfully, a team of scientists just took an important first step towards building a robot that can keep on truckin' even with a couple of bullet holes improve its ventilation. Okay, so maybe they weren't working on killer robots and (probably) didn't subject their research to gunfire, but what they did do is create a soft, flexible electronic material that can automatically repair its circuits when it gets damaged. The new "skin" is made of droplets of liquid metal housed within a rubber-like material that can bend, fold, and stretch. Calling it "self-repairing" is a bit of a misnomer, as the stretchy material won't stitch itself together.
The self-assembling shape shifting killer robots from the Terminator films could be a step closer, thanks to the development of self-propelling liquid metals. A team of Australian researchers is laying the groundwork for T-1000s by creating the basis of soft electric circuits. Unlike modern circuitry found in electronic devices, which remain based on circuits with solid state components, future connections could be much more flexible and able to move and reconfigure as necessary. A team at RMIT University in Melbourne used non-toxic alloys of the metal gallium, which is liquid at close to room temperature. By adding droplets of the alloy galinstan to water and changing the pH, they were able to make the drops move about freely.
