Mass transfer sensors and MEMS devices to measure shear

摘要

The measurement of shear is of great interest to fluid dynamics research,cellular biology,aerospace,marine,environmental and biomedical engineering since shear is the primary means of interaction between a flow and the solid surface.Several critical areas of technology rely on an accurate knowledge of local shear such as heat transfer in turbine blades,electrochemical etching/deposition of copper,metallization using wet-processes in advanced electronics and microfabrication of high-density patterned structures,colloidal transport in environmental engineering and validation of computational fluid dynamics simulations.
