The Underwater communication is very important field in communication in present time. The sensor and acoustic devices used underwater is mostly corroded by the solvents in the water. The underwater parameters like pressure was applied to the design and the six different piezoresistive materials with four different diaphragm material that have been designed and tabulated with the comparison of different materials. In this paper, pressure is considered to be most important part to track and apply on different material that will give us stress, displacement and change in resistivity. The following Stress, Displacement and Resistivity is applied for the design and the results shows the best material that can be used for the design of any underwater sensors and devices. The maximum resistivity is obtained in PZT, SiC and PDMS with several hundred ohms/m change in resistivity. The maximum resistivity obtained for diaphragm materials are PMMA and Silicon Nitride Si3N4. The optimal change in resistivity and displacement was obtained for PZT as piezoresistive material and PMMA as diaphragm material as 2.976E3 ohm/m and several 17µm to 20µm. The novelty of the paper is that it focuses on detection of the direction of the acoustic signal for the underwater applications. The underwater communication devices can have best material for long life and the financial burden will be reduced for the underwater research. [ABSTRACT FROM AUTHOR] |
