Heat Detection Approach

A composite cantilever behaves bimetallically because it is made out of several layers of different materials with different mechanical and thermal properties (Young's modulus, E; and the expansion coefficient, a). This behavior means that every change in the state of a cantilever's layer can induce the entire cantilever to bend. The simplest use of this property is heat detection and, for uniform heating of a two-layered cantilever, the deflection of the cantilever, z, is described as follows (Marie 2002):
