仿蝈蝈脚垫结构表面摩擦力测试数据

数据面向蝈蝈脚垫表面的特殊结构对于液桥粘附的影响，制备仿生棱柱表面，测量仿生表面的摩擦力。。实验台采用两个悬臂梁叠加方式搭建，悬臂梁上贴有应变片搭建的电桥电路，通过将采集的电桥电路电压与悬臂梁所受力做对比，标
定出力与电压之间关系。最终得到法向力和摩擦力量程为 10000mN，最小分度值为 0.2mN 的测力平台，采样频率 10 Hz。在摩擦试验中，将 1.5μL 去离子水注入到仿生棱柱表面（1cm  1cm），然后将玻璃基底覆盖在棱柱表面上，不施加额外的法向力，水平移动玻璃基底以产生横向摩擦（图 1）。在完成一次摩擦测试后，垂直抬起玻璃基底，用无尘纸擦拭干玻璃基底后，重复滑动过程，直到界面接触区域的水消失，进入干摩擦状态。 记录整个过程中摩擦力的最大值，将其作为仿生棱柱表面在此基底上的边界摩擦力。数据量为396KB。

This dataset focuses on the effect of the special surface structure of katydid foot pads on liquid bridge adhesion. Biomimetic prismatic surfaces were fabricated and their frictional forces were measured. The experimental setup was constructed by stacking two cantilever beams, on which strain gauges were attached to form a Wheatstone bridge circuit. The relationship between force and voltage was calibrated by comparing the collected voltage from the Wheatstone bridge with the actual force applied on the cantilever beams. Finally, a force measurement platform was obtained, with a measurement range of 10000 mN for both normal force and friction force, a minimum resolution of 0.2 mN, and a sampling frequency of 10 Hz. In the friction test, 1.5 μL of deionized water was injected onto the biomimetic prismatic surface (1 cm × 1 cm), then a glass substrate was placed on the prismatic surface without applying additional normal force, and the glass substrate was moved horizontally to generate lateral friction (Figure 1). After completing one friction test, the glass substrate was lifted vertically, wiped dry with lint-free wipes, and the sliding process was repeated until the water in the interfacial contact area disappeared, entering a dry friction state. The maximum friction force recorded throughout the process was taken as the boundary friction force of the biomimetic prismatic surface on this substrate. The total size of the dataset is 396 KB.
