The stochastic behaviour of the noncontact Casimir rack and pinion nanosystem is studied in the presence of thermal noise. We identified the Casimir nanomachine as an excitable system where the thermal noise acts as the exciting factor. The excitations appear as “spikes” in the pinion’s temporal position signal. We show that statistical features of the interspike time distribution can be utilized to introduce a dynamic method for measuring low Casimir forces (0.1-1.0 pN) along with the rotational friction coefficient. Other kinds of noise could also be employed to harvest energy using the stochastic Casimir rack and pinion system.
