A stretchable organic digital information storage device has been demonstrated, which enables to advance the development of future smart and digital stretchable electronic systems. The stretchable organic memory with a buckled structure was configured by the mechanical flexible and elastic graphene bottom electrode and polymer compound. The current-voltage curve of the buckled memory showed the electrical bistability with typical write-once-read-many-times (WORM) memory features and a high ON/OFF current ratio of ~105. Even under repetitive stretching, the stretchable organic memory exhibited excellent electrical switching functions and memory effects. We believe this the first proof-of-concept presentation of the stretchable organic nonvolatile memory may progress the development for information storage device in various stretchable electronic applications, such as stretchable display, wearable computer and artificial skin.
