Complementary integrated circuits in an elastic format are essential for systems toward emerging applications in wearable health monitors, soft robotics, and implantable medical devices. However, their development is very nascent, largely owing to the imbalance of p- and n-type elastic transistors. Here, we report fully stretchable complementary integrated electronics combining elastic n-type transistors based on metallic carbon nanotube (CNT)–oped poly{[ N , N ′-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarbo…
