我们研究了压电行走器的两种结构，惯性行走器和摩擦行走器，这两种结构都能够在几毫米的距离上以亚微米级的步长移动样品。我们证明，与预期相反，六个压电片一个接一个剪切的摩擦行走器的操作仍然依赖于惯性滑棒作用。我们研究了应用于连续压电片的步长与上升前之间的时间延迟的关系，发现与步长最小值相关的特征时间是声波沿着压电片之间的杆传播的时间的数量级。
We have examined two configurations of a piezowalker, the inertial and the frictional one, both of which are capable of moving samples with submicrometer steps over a distance of some millimeters. We demonstrated that, contrary to expectations, operation of the frictional walker in which six piezos shear one by one, is still dependent on inertial slip-stick action. We studied the dependence of the step size on the time delay between rising fronts applied to consecutive piezos and we found that the characteristic time associated with the minimum value of the step size is of the order of the time of a sound wave propagating along the rod between the piezos.
