Singapore researchers have developed a smart foam material that allows robots to sense nearby objects, and repairs itself when damaged, just like human skin.<br /><br />Artificially innervated foam, or AiFoam, is a highly elastic polymer created by mixing fluoropolymer with a compound that lowers surface tension.<br /><br />This allows the spongy material to fuse easily into one piece when cut, according to the researchers at the National University of Singapore.
