Owing to their sharp teeth, crickets can eat through new shoots of the stalks of tea plants. Inspired by the special geometrical structure of the teeth of crickets, this study designed a biomimetic cutter to reduce the force and energy required to cut the stalks of tea plants. Therefore, four biomimetic cutters were considered: , , , and . Cutter was a traditional cutter used for comparison with the other three cutters, which were biomimetic. The cutters were manufactured using 3D printing technology and assessed by a texture tester at different loading speeds (5, 10, and 15 mm/s, respectively). The results show that cutter delivered better performance compared to cutter at loading speeds of 5, 10, and 15 mm/s, respectively. However, at 15 mm/s loading speed, the maximum cutting forces required for cutters and were 9.43% and 6.04% lower, respectively, than that for cutter (9.021 N). Similarly, the energies consumed by cutters and were 13.8% and 4.24% lower than that consumed by cutter (1.225 J). In addition, cutter delivered the best results compared to others. Based on the study results, it was concluded that the biomimetic cutters can thus help to optimize the tea harvest.
由于蟋蟀的牙齿锋利，它们能够咬穿茶树茎的新芽。受蟋蟀牙齿特殊几何结构的启发，本研究设计了一种仿生刀具，以降低切割茶树茎所需的力和能量。因此，考虑了四种仿生刀具： 、 、 和 。刀具 是一种传统刀具，用于与其他三种仿生刀具进行比较。这些刀具采用3D打印技术制造，并由质地测试仪在不同加载速度（分别为5、10和15毫米/秒）下进行评估。结果表明，在加载速度分别为5、10和15毫米/秒时，刀具 的性能优于刀具 。然而，在15毫米/秒的加载速度下，刀具 和 所需的最大切割力分别比刀具 （9.021牛）低9.43%和6.04%。同样，刀具 和 消耗的能量分别比刀具 （1.225焦）消耗的能量低13.8%和4.24%。此外，与其他刀具相比，刀具 取得了最佳效果。基于研究结果，得出结论：仿生刀具因此有助于优化茶叶采摘。
