Description

Nonintrusive measurement in a small package at low cost

Quantifying shear stress is important in a large number of situations involving fluid flow, including aerodynamics, hydrodynamics, turbomachinery, and polymer processing among others. The magnitude of the shear stress and the resolution required in various situations can span many orders from milliPascals to kiloPascals or more. The frequency response and spatial resolution needs also vary considerably. Many applications also require directional information and the ability to set up arrays of sensors to collect this information over large areas. This technology ideally meets those needs.
