摘要：
双稳态和突跳失稳是自然界与工程中多种机制的核心，能够在最小能量输入下实现快速运动和大幅形状变化。这些现象可以通过将一张纸弯成拱形并旋转其边缘直至发生突跳来轻松演示。在本快报中，我们表明在此类条带中引入单一折痕会显著改变其突跳特性。特别是，折叠带比常规未折叠情况释放更多能量，从而带来更快的突跳速度。通过数值模拟和理论，我们解释了实验观察结果。我们利用这些发现来编程折叠带的突跳行为，展示了我们的结果如何在例如软体机器人中找到实际应用。
英文摘要：
Bistability and snap-through instabilities are central to various mechanisms in nature and engineering, enabling rapid movement and large shape changes with minimal energy input. These phenomena are easily demonstrated by bending a piece of paper into an arch and rotating its edges until snapping occurs. In this Letter, we show that introducing a single crease in such a strip significantly alters its snapping properties. In particular, folded ribbons release much more energy than the regular, unfolded case, leading to faster snapping speeds. Through numerical simulations and theory, we rationalize our experimental observations. We leverage our findings to program the snapping behavior of folded ribbons, demonstrating how our results could find practical applications, e.g., in soft robotics.
