- W2794260473 abstract "Abstract As the globalization forward the world need high accurateness and reliable devices are indeed. So directional optimization of MEMS piezoelectric hydrophones area of research works are got concentrated in underwater application for ocean research works.Directional optimization and to get landscape the sensitivity and increase the output voltage for that choose rectangular, square and circular diaphragm. Theobjectives of proposed work are is to selecting the proper design for MEMS Piezoelectric hydrophone to improve the sensitivity for different structures like rectangular, circular and square diaphragm and optimizing the high sensitive frequency response by comparing the results obtained from Simulation and analytical validation. Materials considered for this work is PZT, PVDF and ZnO and all properties of the material taken from materials standards, boundary condition is stiffly fixed at the boundaries, load will be applied on the diaphragms as constant pressure of 1 Pascal and variable pressure of 1pa to 10pa. Modelling and directional optimization of piezoelectric hydrophone has been done by using COMSOL Multiphysics software. Interpretation of numerical values like electric voltage (V), Mechanical displacement and Vonmises stress. These outputs from COMSOL Multiphysics are compared with theoretical results to get landscaped sensitivity, Frequency analysis is done from varying pressure values. The optimized results from testing are suggest that this device could be used to detect underwater sounds in various applications." @default.
