On page 4639, S. W. Nam and co‐workers present a stretchable photodetector with enhanced, strain‐tunable photoresponsivity based on engineering 2D graphene into crumpled 3D structures. The crumpled graphene photodetector demonstrates ca. 400% enhanced photo‐responsivity, led by an order‐of‐magnitude enhanced optical extinction over flat graphene. The highly flexible system has future potential for integrated biomedical optical sensing systems.
