User-Interactive stretchable devices act as a significant role to transform an appearance of their color and/or transparency when the mechanical stimuli apply, making them useful for various applications such as electronic skin (e-skin), smart windows, and soft robotics. Moreover, researches about the stretchable devices have recently been widely studied on thermal application for thermotherapy. We fabricate a versatile stretchable device consisting of strain-responsive silver nanowire networks on randomly patterned wrinkles and thermochromic layer being coated on the surface. The prepared stretchable strain sensor exhibits high stretchability with a linear sensitivity. The stretchable sensor can be used as a Joule-heating device with a simply tunable heat generation by utilizing the tensile strain. A user-interactive strain sensor was demonstrated to confirm the usefulness of our approach to the application including skin-attachable motion detection and thermotherapy.
