The challenge of continuously powering the wireless sensor network located at remote areas has been resolved by the emergence of piezoelectric energy harvester. This paper evolved a new idea of using different piezoelectric materials together within segmented doubly clamped bimorph piezoelectric energy harvester (DCBPEH). The finite element modeling of the device has been presented here using COMSOL multiphysics software. This paper starts with concept of strain nodes and further better performance of segmented electrodes-based beam over the continuous electrode-based beam has been achieved. Next, a performance analysis study with continuous electrode-based beam has been carried out for different variants of two piezoelectric materials, namely, PMN-xPT and PZT. From this study, PMN-35%PT and PZT-5H piezoelectric materials are found to be best variants. Finally, the performance of segmented DCBPEH has been observed for different positioning formats of PMN-35%PT (M1) and PZT-5H (M2) piezoelectric materials on different segments of the beam. From this analysis, M1–M1–M2 and M2–M1–M1 are noted to be two favorable positioning formats which provide similar and maximum performance (7.78 mW) as compared to other formats.

压电能量收集器的出现解决了为偏远地区的无线传感器网络持续供电的挑战。本文提出了在分段双钳位双压电晶片压电能量采集器（DCBPEH）中一起使用不同压电材料的新思路。此处使用COMSOL Multiphysics软件介绍了设备的有限元建模。本文从应变节点的概念入手，实现了分段的基于电极的束优于连续基于电极的束的更好性能。接下来，针对两种压电材料的不同变体，即PMN- x，进行了基于连续电极束的性能分析研究。PT和PZT。通过这项研究，发现PMN-35％PT和PZT-5H压电材料是最好的变体。最后，对于在束的不同段上的PMN-35％PT（M1）和PZT-5H（M2）压电材料的不同定位格式，已经观察到分段DCBPEH的性能。通过此分析，注意到M1-M1-M2和M2-M1-M1是两种有利的定位格式，与其他格式相比，它们提供了相似的最大性能（7.78 mW）。
