3D Printing of Transparent and Conductive Heterogeneous Hydrogel–Elastomer Systems. Issue 10 (11th January 2017) - Tian, Kevin
Abstract : A hydrogel–dielectric‐elastomer system, polyacrylamide and poly(dimethylsiloxane) (PDMS), is adapted for extrusion printing for integrated device fabrication. A lithium‐chloride‐containing hydrogel printing ink is developed and printed onto treated PDMS with no visible signs of delamination and geometrically scaling resistance under moderate uniaxial tension and fatigue. A variety of designs are demonstrated, including a resistive strain gauge and an ionic cable.
