　　Large deformation of soft materials is harnessed to provide functions in the nascent field of soft machines.This paper describes a new class of systems enabled by highly stretchable,transparent,stable ionogels.We synthesize the ionogel by polymerizing acrylic acid in ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate([C2mim][EtSO4]).Using the ionogel and a dielectric elastomer,we fabricate electromechanical transducers that achieve a voltage-induced areal strain of 140%.The transparency of the ionogels enable the transducers with conductors placed in the path of light,and the nonvolatility of the ionogels enable the transduces to be used in the open air.
