Abstract

This study investigates the bimetallic effects in a microcantilever biosensor induced due to change in ambient temperature. The cantilever is subject to both thermal and surface stresses. The biosensor exploits the surface-stress induced deflection to analyse the unknown molecules. However, due to bilayer structure of the cantilever thermal deflections are produced, which are a common source of noise in the deflection measurement. Thus, distinguishing surface-stress induced deflections from the thermal deflections is critical in accurate measurement by the biosensor. In this theoretical work, we show that both thermal stress and surface stress have linear effect on the cantilever deflections, and hence can be added algebraically to determine the absolute deflection produced entirely due to the surface stress variation.
