Of concern the paper is a review of electro-osmotic flow of a viscoelastic bio-fluid in the light of wall shear stress developed due to the velocity gradient across the channel. The channels are in a state of oscillatory motion and the flow is driven by an alternating electric field. Analytical solutions are derived from the set of governing equations under boundary layer approximations. For an illustrative purpose, a case study is made by analyzing the flow behavior, taking blood sample in which the viscoelastic properties are modeled as a determining factor for the case of fully developed flow in a micro channel. It is revealed that a higher viscoelastic coefficient results in a stronger wall shear stress in the time periodic profile, characterized by second grade viscoelastic model. The results given here seems to be worthy of attention, for an accurate interpretation of wall shear stress during arterial blood flow through a micro-vessel.
