Strain Gauge - Basic Concept

A strain gauge is a primary transducer used for the measurement of physical quantities such as displacement, force, pressure etc.It is operates on the principle of 'Piezoresistive effect'. For signal conditioning, a Wheatstone bridge is used, so that we get an output in the form of voltage. There are two important parameters associated with a strain gauge :- 1. Poisson's Ratio 2.
