What is Understanding Strain Gauges and Their Use about?

Strain gauges are used to measure strain, which is a change in length per unit length of a material under loading. Strain gauges work by having a change in electrical resistance proportional to experienced strain, according to their gauge factor. Strain gauges are commonly constructed of metal foil or semiconductor material and bonded to the surface of a specimen. A Wheatstone bridge circuit is used to convert small resistance changes in the strain gauge into measurable voltage changes. Multiple strain gaug
