Liquid core fibers: A data river runs through them

Data and signals can be transmitted quickly and reliably with glass fibers—as long as the fiber does not break. Strong bending or tensile stress can quickly destroy it. An Empa team has now developed a fiber with a liquid glycerol core that is much more robust and can transmit data just as reliably. And such fibers can even be used to build microhydraulic components and light sensors.
