Pages: 640 - 643

Keywords: MEMS, microsystems, pressure sensor, diaphragm

An analytical solution for large deflections of a clamped circular diaphragm with built-in stress is presented. The solution is directly applicable to micromachined pressure sensors. The solution is compared to finite element analysis results and experimental data from a surface-micromachined pressure sensor.
