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 ...

We are always impressed with something so simple can actually be so complex. For example, what would you think goes into an analog computer? Of course, a “real” analog computer has opamps that can do ...

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 ...
