Submission + - MIT Cloth that can emit and receive sounds (

La Gris writes: "In the August issue of Nature Materials, Fink and his collaborators announce a new milestone on the path to functional fibers: fibers that can detect and produce sound. Applications could include clothes that are themselves sensitive microphones, for capturing speech or monitoring bodily functions, and tiny filaments that could measure blood flow in capillaries or pressure in the brain. The paper, whose authors also include Shunji Egusa, a former postdoc in Fink's lab, and current lab members Noémie Chocat and Zheng Wang, appeared on Nature Materials' website on July 11, and the work it describes was supported by MIT's Institute for Soldier Nanotechnologies, the National Science Foundation and the U.S. Defense Department's Defense Advanced Research Projects Agency."
