Paper memory by all printing technology

We report the first paper-based nonvolatile memory device by means of an all-printing approach using a sequence of inkjet and screen printing techniques to fabricate a resistive random access memory on paper. The printed paper-based memory devices (PPMDs) can be labeled on electronics or living objects for multi-functional, wearable, on-skin, and biocompatible applications. The PPMDs would be a key electronic component to fully activate a paper-based circuit and can be directly implemented in medical biosensors, multi-functional devices, and self-powered systems.
