Soft, stretchable, and wearable electronic devices have been studied for their potential use in various applications that cannot be achieved with conventional rigid devices. A common method of manufacturing stretchable electronic devices is to design all constituent materials to be stretchable. Another approach is to design the substrate so that the strain is concentrated on the interconnects and strain-free or limited strain on the unit area. The former approach can provide high integration, but there is a limit to making all elements of a device stretchable. Herein, we introduce a simple method to fabricate a photo-crosslinkable, transparent elastomer substrate for stretchable electronics and its application to physical sensors. The substrate can be selectively crosslinked by exposure to UV light in order to form a rigid region using a patterned mask. Rigid island structures with repetitive rigid-soft-rigid systems can facilitate the development of strain insensitive pressure sensor.
