In this paper, modeling and simulation results of a thermal sensor which is capable of producing increase in length and deformation with increase in temperature is analyzed. Different geometries of a microcantilever beam are accounted. Further, the simulated results are used to develop an artificial neural network (ANN) model of slotted triangular type of microcantilever. A comparative study of COMSOL and ANN results of different types of cantilever models is also presented.Keywords: The Thermalrmal rmal sensor, MEMS, artificial neural network models Cite this Article: Shettar Rachita, Sheeparamatti BG.
