The engineering measurement called strain is the deformation per unit of length of a material when force is applied to it. In other words, strain is a ratio of a material's change in length from an ...

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 ...

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 ...
