Abstract

The need to measure strain occurs in a variety of industries, ranging from aerospace design to civil engineering to traffic sensors to robotic manipulators. Measuring the deflection of a structure gives design engineers data needed to build safer and more efficient systems. Typical measurements can be approximately an inch of deflection over a 100 foot gage length (8 millistrain) for structural applications, to a micron of deflection over a meter gage (1 microstrain) for materials testing. Strain measurements are made along one, two, or three spatial axes, depending on the need.
