Abstract

The use of AFM in nanotribology is limited by our capacity to fully estimate the cantilever’s properties. Especially, cantilever’s stiffness plays a major part in the estimation of the contact forces. In this paper, we look at the 3D misorientation of a perfect triangular cantilever in static. The analysis was carried using Finite Element Analysis to estimate the stiffness matrix at the tip end. Results show a small influence of the misorientation in bending. However misorientation along the torsion axis has a notable impact on the estimation of lateral forces and introduce a mechanical cross-talk that can influence machine’s measurement.
