["Field concentration is often regarded as a problematic issue in soft electronics applications, especially when using curved electrodes, and in particular, those with sharp edges. However, field concentration can be turned into an advantage with appropriate device design. Here, the applications of field concentration in hydrogel-elastomer devices are explored. Three different types of electroluminescent hydrogel-elastomer devices are made using different types of electrodes and different light patterns. In addition, the effect of the field concentration can be extended into the bulk of the elastomer by preparing porous silicone elastomers and filling them with silicone oil. These devices are shown to be flexible and possess both good luminance and a long lifetime.","The commonly regarded problematic field concentration along electrode edges is utilized to fabricate three easily prepared soft hydrogel-elastomer electroluminescent devices: a hydrogel device, a wire device, and a silicone oil lamp. All fabricated devices are stable, with no changes observed over the course of 5.4 million cycles.image"]
