Design‚ Optimization and Simulation of an Electric Field Microsensor based on PZT Piezoelectric Interdigitated Cantilevers Ke Feng1, 2, a*, Jianhua Tong1, b ,Yu Wang1, 2, c and Shanhong Xia1, d 1State Key Laboratory of Transducer Technology, Institute of Electronics, Chinese Academy of Sciences, Beijing, P.R.China 2Graduate University of Chinese Academy of Sciences, Beijing, P.R.China akingfisher3721@126.com, bjhtong@mail.ie.ac.cn, cwangyuiecas@163.com, dshxia@mail.ie.ac.cn Keywords: Electric field microsensor, Piezoelectric , PZT driven.
The tensed piezoelectric material tilts the comb structure upward, and the compressed piezoelectric material tilts the comb structure bends downward, as shown in Figure 3(a) and (c).
In the proposed model we assumes that insulator layer, bonding layer and electrode layer are negligible because elastic substrate and piezoelectric materials layer are much more thickness than other layers.
As the material properties of the thin film PZT layer have not yet been determined, and hence the values of the bulk PZT 52/48 are chosen.

Introduction The rapid development of laser technologies provides new opportunities for precise processing of materials, as compared to the traditional methods.
Processing of materials by continuous wave lasers and pulsed lasers is widely applied for forming two-dimensional and three-dimensional micro- and nanostructures in metals, semiconductors, polymers and so on.
