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.

集成了传感器和内存的人机交互多功能电子墙纸

物联网概念促进了可穿戴设备和机器人应用中的人机交互电子学的研究。一种有趣的应用是墙纸，用于监视房间环境并充当电子留言板。为了演示电子墙纸（电子墙纸）的潜力，本研究准备了与触觉触摸传感器阵列集成为消息板的灵活的非易失性浮栅随机存取存储器（FGRAM）阵列。另外，还层压了温度传感器阵列以监视室温。除了机械灵活性以外，还对柔性FGRAM的基本特性进行了表征，包括隧穿电介质厚度，编程电压和编程时间相关性。最后，
