Soft and stretchable electronic devices are compelling due to their application in various fields. Among the various materials, silicones are widely used due to their softness and stretchability and easy process to get patterned structures by replica molding. A commercially available silicone, Exsil 100 that exhibits ultrastretchability, ultrasoftness and high tear strength is recognized as promising material for fabricating soft and stretchable electronics, however the patterned structures are prone to collapse when they are released from mold due to ultrasoftness of the materials. Herein, we developed ultrasoft and ultrastretchable electronics by non-lithographic approach utilizing Exsil silicone and oxidized liquid metal as an elastomeric substrate and electrode, respectively. The oxidized liquid metal with tuned surface tension imparted superior wettability and rheology for printing which enabled printing of desired electrodes of different geometries on the elastomeric substrate
