Soft electronic devices can possess mechanical properties similar to human skin, offering a platform for next-generation wearable devices and electronic skins for robots. In this talk, I will discuss a range of soft transducers using stretchable electronic materials. For example, we have developed a conducting polymer that can be intricately patterned in high resolution (<10 µm). These high optoelectrical properties have been fully harnessed in soft electronic devices, including skin-like transparent sensor arrays, highly skin-conformable displays, and stretchable semiconductor devices.
