摘要：
A model that predicts minimal length and thickness of all ceramic two layer cantilever sensor for chemical and biological detection is proposed. The model allows the estimation of minimal length and thickness where the conditions for the safe cantilever operation are satisfied. Two materials have been chosen for the consideration of the piezoelectric and non-piezoelectric layers in the layered cantilever. A piezoelectric material is lead zirconate titanate and a non-piezoelectric material is boron carbide. Different conditions, such as von Mises criterion and Mohr's strength theory are considered to find safe stress level in the clamped cross-section of the cantilever.
