Title: Thermal-stress modeling of an optical microphone at high temperature.

Technical Report ·
DOI:https://doi.org/10.2172/1005061· OSTI ID:1005061

To help determine the capability range of a MEMS optical microphone design in harsh conditions computer simulations were carried out. Thermal stress modeling was performed up to temperatures of 1000 C. Particular concern was over stress and strain profiles due to the coefficient of thermal expansion mismatch between the polysilicon device and alumina packaging. Preliminary results with simplified models indicate acceptable levels of deformation within the device.
