Abstract: A cco rding to the sensing st ructure of a p ract ical silicon resonant p ressure m icro sen2 so r w ho se p relim inary sensing unit is a square silicon diaph ragm and the final sensing unit is a sili2 con beam resonato r, its operat ing mechanism is analyzed. The thermal resisto r acts as the excited unit, and the p iezo resist ive unit acts as the detecto r, fo r the abovem icro senso r. By using the am2 p litude and phase condit ions, the self2excit ing clo sed loop system is invest igated based on the oper2 at ing mechanism fo r the abovem icro senso r. The temperature p rofilemodel and the thermal st ress model are established fo r the beam resonato r of the m icro senso r. Mo reover, the thermal featureis simulated and analyzed fo r the above m icro senso r.
Key words: thermal excitat ion; resonant senso r; silicon m icro st ructure; p ressure senso r
