Paper Abstract

A laboratory model of a gas sensor substrate produced in microelectronic technology has been experimentally analyzed and simulated by means of a 3D FEM model. This paper discusses its thermal and mechanical behavior under different working temperatures. The thermal expansion mismatch between different materials induces thermal stresses and structure deflection. Simulated and experimental results are proved to be in good agreement. Moreover, the proposed design offers low-power consumption, good thermal uniformity, low thermal inertia and mechanical stability up to 650 degrees Celsius.
