DEVELOPMENT OF TEMPERATURE SENSOR FOR AUTOMOTIVES

The paper presents a micro-electromechanical system (MEMS) temperature sensor that has been designed using COMSOL Multiphysics 6.0 software for use in predicting the temperature of automotive parts. Due to its versatility, the shape of this design employs a meander, and this involves joule heating physics. It can measure temperatures ranging from -200°C to 600°C. It clearly shows the variation of resistance with temperature. For this design, copper material is used because of some advantages: high electrical conductivity, thermal conductivity, and mechanical strength, which help in withstanding harsh climate conditions in the stratosphere. This sensor works based on the principle of temperature dependence of resistance; that is, the resistance of the material increases or decreases based on temperature.
