A strain gauge is used to measure the strain on an object. It is a very thin, flat coil of conductive wire. (Editor's note: strain “gauge” is often spelled as “gage”; why this is so, and which is ...

Strain gages are sensing devices used in a variety of physical test and measurement applications. They change resistance at their output terminals when stretched or compressed. Because of this ...

Many conventional strain gages are similar in appearance to Figure 1. A serpentine pattern etched into a metal foil creates a relatively high resistance in a small space. The foil is bonded to a thin ...

The levels of mechanicalstrain most typically measured with strain gauges are very small and precise.Consequently, changes in resistance are also very small and thus cannot bemeasured directly with an ...
