Abstract

This paper presents the design, modeling, and simulation of Lead Zirconate Titanate (PZT) based micro-sensors. The PZT thin film is polarized in-plane in stead of through-thickness, and thus utilizes d 33 working mode other than d 31 working mode. Micro-sensors using cantilever structures and InterDigital Electrodes (IDE) are numerically analyzed by Finite Element Analysis (FEA) method. The relation between the sensitivity and the IDE configurations is presented, and some results and conclusions can be used as future design guidelines. The simulation results show that the voltage sensitivity of micro-sensors utilizing d 33 mode can be several times or even tens times higher than those utilizing conventional d 31 mode. The high sensitivity together with the ease of fabrication makes micro-sensors using d 33 mode more competitive and attractive.
