论文摘要
机械计算最近由于将传感和计算嵌入新的可编程超材料类别的潜力而引起了人们的重新兴趣。但是，要意识到这一点，必须将信号从设备的一个部分推向另一部分，并以可以牢固重置的方式进行。我们研究了在能量上沿着可动的机械级联级联中信号的传播。通过识别扰动的穿透长度，我们表明信号可以传播有限距离的上坡并绘制参数，以便发生这种情况。软弹性体的实验证实了我们的结果。
Mechanical computing has seen resurgent interest recently owing to the potential to embed sensing and computation into new classes of programmable metamaterials. To realize this, however, one must push signals from one part of a device to another, and do so in a way that can be reset robustly. We investigate the propagation of signals in a bistable mechanical cascade uphill in energy. By identifying a penetration length for perturbations, we show that signals can propagate uphill for finite distances and map out parameters for this to occur. Experiments on soft elastomers corroborate our results.
