Here, we develop a microfluidic device with embedded pressure sensors to measure elasticities of endothelial cells in two orthogonal directions along the substrate on which they attach. The attachment makes the membrane flexural rigidity change and further causes the pressure sensor sensitivity variation. In the experiment, we exploit a fluidic shear stress to align endothelial cells. The pressure sensors are used to estimate the endothelial cells elasticities in directions parallel and perpendicular to the flow directions based on mechanics plate theory. Copyright ?
