Abstract

The internet of things concept has promoted research on human-interactive electronics for wearable devices and robotic applications. One interesting application is wallpaper to monitor a room environment and to act as an electronic message board. To demonstrate the potenital of electronic wallpaper (e-wallpaper), this study prepares a flexible nonvolatile floating gate random access memory (FGRAM) array integrated with a tactile touch sensor array as the message board. Additionally, a temperature sensor array is also laminated to monitor the room temperature. Besides the mechanical flexibility, the fundamental properties of flexible FGRAMs, including the tunneling dielectric thickness, program voltage, and program time dependencies, are characterized. Finally, e-wallpaper is demonstrated as a first proof-of-concept to show a possible platform for future macroscale flexible electronics.
