This paper discusses the optimization of a micro-pump composed by deformable polymeric membrane in contact with reservoir and examines the effect of the materials property at the performance and the functionality of the system. The Neo Hookean  hyperelastic material model is used to simulate the deformation of polydimethylsiloxane (PDMS) elastomer and compared with Poly methyl methacrylate (PMMA). The results of simulation by finite element are presented and discussed.

 In second steps we study the power to inject by active membrane a Newtonian and a non Newtonian fluid in microcanalization, the power law is used to model the variation of the blood viscosity and precise the maximum value of flow rate at minimum applied pressure and control the fluid transportation.

This type of micropump appears to be suitable for biomedical applications and demonstrate the versatile use of active membrane as moving parts to inject the fluids us blood or glucose.
