Abstract
In this article we present an FEM analysis of the change in resonance behaviour of 5 mm long piezoresistive cantilevers when they are modified with pencil shaped diamond tips of varying length. In a setup with glued cantilever base the length of the fixed bearing was examined as well. Simulations show that for a free cantilever base length of one fifth of the base no base oscillations occur. Base oscillations only occur for higher order modes of resonance with free base lengths greater one fifth.
