Abstract: The benefits in emloying plastics material in microfluidic devices manufactures are extremely attractive that include reduced cost and simplified manufacturing procedures, particularly when compared to silicon. An additional benefit is the wide range of available plastic materials which allow the manufacturer to choose materials' properties suitable for their specific application. The Polydimethylsiloxane is commonly used in a wide range of microfluidic applications due to its flexibility and low cost. In addition the properties of the Polymethyl methacrylate such as the low cost, high transparency, and good chemical properties are needed in microfluidics applications. In this paper, we have used Finit Elements method to simulate the mechanical behavior of Polydimethylsiloxane and Polymethylmethacrylate using hyper elastic and linear elastic model. Sevral parameters have been studied; such as, thickness and number of mesh in order to optimize the dimension of the membrane. Also, we have studied the impact of the mesh form on the membrane’s displacement.

 

Keywords: Finite Element, Microfluidic devices, Hyperelastic membrane.
