Abstract: A shear stress sensor for use within a substrate exposed to a fluid flow. The sensor comprising a cavity defined within the substrate; electrolyte fluid within the cavity; and an amperometric system further comprising oppositely disposed first and second electrodes within the cavity for measuring current flow between the first and second electrodes, wherein fluid motion within the cavity is responsive to shear stress and measured current flow is responsive to the fluid motion.
