摘要：

This paper focuses on the study of sensitivities of microcantilever chemical sensors based on SOI POLYMUMPS process. Through changing the geometry of beams and analyzing resonance frequency shift in a dynamic mode by using FEA (finite element analysis) method, the most sensitive structure, which is a triangle, is selected out from various kinds of beam designs. The relation between the sensitivity and the parameters such as length L, width W and thickness t is obtained by dynamic analyzing with the commercial software Intellisuite. This research provides the primary instruction for developing high sensitive multi-array biochips aiming at analyzing multiple parameters in parallel.
