Researchers at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are working on a smart fiber that can detect slight changes in pressure and strain and can withstand large amounts of deformation. The fiber is the perfect candidate for use in developing smart clothing and prosthetics. The fibers are created using a technique similar to manufacturing fiber-optics. Originally only used for rigid fibers, the research team adapted the technique to be used for making elastic fibers. Read more about these smart fibers at EFPL.
