Liquid core fibers: A data river runs through it
Dübendorf, St. Gallen und Thun, 29.7.2021 - 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.
