This paper presents the design and testing of a one-axis piezoelectric accelerometer made from cellulose paper and piezoelectric zinc oxide nanowires (ZnO NWs) hydrothermally grown on paper. The accelerometer adopts a cantilever-based configuration with two parallel cantilever beams attached with a paper proof mass. A piece of U-shaped, ZnO-NW-coated paper is attached on top of the parallel beams, serving as the strain sensing element for acceleration measurement. The electric charges produced from the ZnO-NW-coated paper are converted into a voltage output using a custom-made charge amplifier circuit. The device fabrication only involves cutting of paper and hydrothermal growth of ZnO NWs, and does not require the access to expensive and sophisticated equipment. The performance of the devices with different weight growth percentages of the ZnO NWs was characterized.
本文介绍了一种由纤维素纸和在纸上水热生长的压电氧化锌纳米线（ZnO NWs）制成的单轴压电加速度计的设计与测试。该加速度计采用基于悬臂的结构，有两个平行的悬臂梁，上面附着一个纸质的质量块。一块U形的、涂有ZnO NWs的纸附着在平行梁的顶部，作为用于加速度测量的应变传感元件。涂有ZnO NWs的纸产生的电荷通过定制的电荷放大电路转换为电压输出。该器件的制造仅涉及纸张切割和ZnO NWs的水热生长，不需要使用昂贵和复杂的设备。对具有不同ZnO NWs重量生长百分比的器件性能进行了表征。
