Researchers are on the verge of creating electronic skin - a component of robots of the future made with "soft" features. Softness here means the opposite of rigidity. The softer the part, the more the part can be bent, molded, and shaped to meet challenges. The problem, said researchers this week, is that existing robots have set of necessary parts that aren't by their nature soft. These researchers presented a "skin-like electronic system" with which the gap between hard and soft can be bridged.
