This paper presents a new electric field microsensor based on the structure of PZT (PbZr_xTi_(1-x)O₃) piezoelectric cantilever beams. The design, fabrication and preliminary experimental result of the electric field microsensor are described in this paper. This sensor consists of piezoelectric interdigitated cantilever beams. Each beam is a multilayer compound structure (Al/Si₃N₄/Pt/PZT/Pt/Ti/SiO₂/Si), and it has the function of shielding electric field and inducing charge. The ability of induced charge and driving mechanism were simulated by finite element analysis method, and the simulation result was adopted as reference. The electric field microsensor was fabricated by Micro-Electromechanical Systems (MEMS) technique,and the PZT layer was prepared by sol-gel method. The preliminary experimental result showed that this microsensor has a good response to the intensity of applied electric field..
