C. J. Walsh, J. A. Lewis, and co-workers report a new method for fabricating capacitive soft strain sensors via multicore-shell fiber printing. These fiber sensors consist of four concentric, alternating layers of ionic fluid and silicone elastomer that serve as conductive and dielectric materials, respectively. The image highlights both multicore-shell fiber printing using model fluorescent inks as well as resulting fiber sensor and its textile integration.
