摩擦起电现象在生活中十分常见，自从王中林院士提出摩擦纳米发电机的概念以后，摩擦纳米发电机在收集日常生活中的能量以及制作自驱动传感器方面应用逐渐增多。本论文中，基于垂直接触—分离模式的摩擦纳米发电机设计并制作了发电机单元。采用铝片和PDMS作为摩擦材料，通过激光切割的方法制作起支撑作用的条形结构模板，得到具有条形结构的PDMS摩擦层。探究了压力以及发电机单元的面积对发电机短路电流和开路电压输出信号的影响，并且测量了发电机单元的电压和电流信号随外接负载的变化，以及输出功率密度随负载阻值的变化，确定最佳输出功率的负载范围。同时测试了器件的耐久性和稳定性。将发电机单元进行组合，形成智能鞋垫。通过LabVIEW将发电机单元产生的电信号峰值大小转换为指示灯亮的数量，实现了电流信号强弱的可视化和对力大小的传感。最后，通过实时监测结果的反馈，成功对走姿中“内八字”和“外八字”现象进行动态监测。

Triboelectrification is a very common phenomenon in our daily life. Since professor Zhonglin Wang invented the Triboelectric nanogenerator, this phenomenon is widely used to collect energy around us and fabricate the self-powered sensors. Here, the triboelectric nanogenerator has been designed and fabricated based on the vertical contact-separation mode. Aluminum and PDMS with a periodic strip structure for supporting are acted as the two triboelectric layers. The output short-circuit current and open-circuit voltage of triboelectric nanogenerator are explored by changing the applied force and the area of the triboelectric nanogenerator. And the variation of the voltage, current and the output power density with the external load resistance has been measured. In the same time, the durability and stability has been measured. Further, a poor intelligent insole is fabricated by combining four generator units. By converting the electric signal from different nanogenerator to the number of lighting indicator lights through LabVIEW, the intensity of force is visualized. Based on the real-time monitoring result, the phenomenon of “inner eight characters” and “outer eight characters” in walking can be demonstrated.
