Description 557-562
Present study consists the behaviour of Polydimethylsiloxane (PDMS) as
a vibrating membrane for acoustic signal detection application. Modelling and
simulation work was performed using ANSYS 12.1. Theory of acoustic impedance
showed that PDMS acting as an acoustic membrane is acoustically matched when
operated in water rather than air with 96.7% energy transfer efficiency. Effect
of hydrostatic pressure on the membrane deflection was studied for a very
shallow application with depth level ranging from 0 to 1m. Effect of PDMS
structural geometry on its deflection behaviour was also studied by varying the
radius and thickness of the membrane structure. Finally, according to the
deflection theory, the type of membrane deflection was classified based on the
variation of radius to thickness ratio of the membrane as well as the applied
pressure.
