纸基功能电子器件在射频识别（RFID）、传感器、晶体管和微机电系统（MEMS）中的应用开创了新时代。作为构建一个可以独立和可持续工作的全纸基系统的重要组成部分，纸基电源是不可或缺的。在这项研究中，我们展示了一种纸基纳米发电机（pNG），可以将微小的机械能转化为电能。pNG依赖于静电效应，并且纸上的静电荷通过电晕方法产生。单层pNG的瞬时输出功率密度在110 V电压下达到1.90.6 μW cm−2，瞬间点亮了70个LED。此外，通过将pNG粘附到可移动物体上，例如书页，从翻页的机械动作中获得的功率可以驱动LED，这在构建基于纸张的自供电系统和作为有源传感器方面表现出了出色的潜力。
Paper-based functional electronic devices endow a new era of applications in radio-frequency identification (RFID), sensors, transistors and microelectromechanical systems (MEMS). As an important component for building an all paper-based system that can work independently and sustainably, a paper-based power source is indispensable. In this study, we demonstrated a paper-based nanogenerator (pNG) that can convert tiny-scale mechanical energy into electricity. The pNG relies on an electrostatic effect, and the electrostatic charges on the paper were generated by the corona method. The instantaneous output power density of a single-layered pNG reached ∼90.6 μW cm−2 at a voltage of 110 V, and this instantaneously illuminated 70 LEDs. In addition, by sticking the pNG to a movable object, such as the page of a book, the power harvested from the mechanical action of turning the page can drive an LED, which presents its outstanding potential in building paper-based, self-powered systems and as active sensors.
