开发具有小型化集成和功能的轻量级、灵活和可持续的物联网传感器网络仍然是一项挑战，也是对下一代电子设备的迫切需求。纸质电子作为未来绿色电子的主要代表之一，被认为是满足不断升级的电子产品消费的最令人振奋的技术之一。在这里，我们提出了一种超薄(约200微米)、轻质的纸基自供电系统，它由纸基摩擦电/压电混合纳米发电机和纸基超级电容器组成。在翻页和移动书籍/文档等人类动作下，内置在智能书籍/文档中的自制自供电系统能够为便携式设备持续供电，例如连续驱动LED和温度/湿度传感器。通过信号处理电路，进一步将纸质系统发展成为文件管理和智能阅读的无线人机交互系统。自供电系统的超薄和高度灵活的特性不仅赋予了该设备用于便携设备的发电功能，而且在开发物联网潜在应用时也建立了无线人机交互。
Developing lightweight, flexible and sustainable sensor networks with miniaturized integration and functionality for the Internet of Things (IoT) remains a challenge and an urgent demand for the next-generation electronic devices. Paper-based electronics, which represents one of the main green electronics in the future, have been considered as one of the most exciting technologies to meet the consumption of the frequently upgraded electronics. Here, we presented an ultrathin (about 200 mu m) and lightweight paper-based self-powered system that consists of a paper-based triboelectric/piezoelectric hybrid nanogenerator and a paper-based supercapacitor. Under human motions such as flipping the page and moving the book/document, the as-fabricated self-powered system built-in the smart book/document was capable of sustaining power for portable devices, such as continuously driving LEDs and the temperature/humidity sensor. With the signal-processing circuit, the paper-based system was further developed into a wireless human-machine interaction system for documents management and smart reading. The ultrathin and highly flexible characteristics of the self-powered system not only endow the device with power generation feature for portable devices, but also build up the wireless human-machine interactions in developing potential applications for the IoT.
