What is Study of the Dynamic Behaviour of a Piezo-walker about?

We have examined two configurations of a piezo-walker, the inertial one 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.
