本文介绍了一种新型的纸基压电触摸板集成氧化锌纳米线（ZnO NWs），它可以作为用户界面在纸基电子产品。这些触摸板的传感功能是通过使用简单、具有成本效益的水热方法在纸上生长的ZnO纳米线的压电特性实现的。一片具有两个丝网印刷银电极的ZnO-NW纸形成触摸按钮，并且使用电荷放大器电路将来自按钮的触摸感应电荷转换为电压输出。由按钮阵列组成的触摸板可以容易地集成到纸基电子设备中，允许用户输入用于各种目的的信息，例如编程、身份检查和游戏。该设计具有制作简单、成本低、结构紧凑、与印刷电子技术兼容性好等特点，进一步丰富了纸基电子的可用技术。
This paper describes a new type of paper-based piezoelectric touch pad integrating zinc oxide nanowires (ZnO NWs), which can serve as user interfaces in paper-based electronics. The sensing functionality of these touch pads is enabled by the piezoelectric property of ZnO NWs grown on paper using a simple, cost-efficient hydrothermal method. A piece of ZnO-NW paper with two screen-printed silver electrodes forms a touch button, and touch-induced electric charges from the button are converted into a voltage output using a charge amplifier circuit. A touch pad consisting of an array of buttons can be readily integrated into paper-based electronic devices, allowing user input of information for various purposes such as programming, identification checking, and gaming. This novel design features ease of fabrication, low cost, ultrathin structure, and good compatibility with techniques in printed electronics, and further enriches the available technologies of paper-based electronics.
