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.
水凝胶-介电弹性体系统，聚丙烯酰胺和聚二甲基硅氧烷（PDMS），被用于挤出打印集成器件制造。开发了一种含氯化锂的水凝胶打印墨水，并将其打印到经过处理的 PDMS 上，在适度的单轴拉伸和疲劳下，没有分层和几何缩放的明显迹象。展示了多种设计，包括电阻应变计和离子电缆。
