Abstract
The steering positioning and fabrication operations in nano scale have been hampered by the uncertainties which come from the macro parts of nanopositioners Among those uncertainties the nonlinearities of piezo scanners have the highest contribution which should be identified and compensated On the other hand the recognition of the effects of macroscale nonlinearities on smallscale dynamics requires the simultaneous consideration of both the macro and smallscale dynamics This necessitates the implementation of multiscale methods In this article a fixed interfacial multiscale method FIMM that includes the effects of hysteresis has been used for the computationally and mathematically efficient modeling of nanopositioners This method presents an improved coupling approach that can be used to study the imaging and manipulation of nanoparticles from one to several hundred nanometers in diameter subjected to nonlinear as well as linear positioning schemes After comparing the applied hysteresis model with some previous experimental works the dynamics of imaging and automatic manipulation of nanoparticles have been studied and some useful results have been presented This paper opens a new window to the recognition and compensation of the errors of macroscale nonlinearities imposed on smallscale dynamics
