MIT researchers create fibres that can detect and produce sound

For centuries, 'man-made fibres' meant the raw stuff of clothes and ropes; in the information age, it's come to mean the filaments of glass that carry data in communications networks. But to Yoel Fink, an Associate professor of Materials Science and principal investigator at MIT's Research Lab of Electronics, the threads used in textiles and even optical fibres are much too passive. For the past decade, his lab has been working to develop fibres with ever more sophisticated properties, to enable fabrics that can interact with their environment...
