Abstract

Abstract : Scanning electron micrographs of hollow elastic fibers. Injecting the core with liquid metal renders the fibers conductive. As Michael D. Dickey and co‐workers present in article number1605630, two or more fibers twisted together can sense large amounts of torsion due to changes in geometry, and therefore capacitance, between the fibers. Self‐capacitance between fingers and the metal in the fibers allows for touch sensing.
