Strain gauge
A tiny resistive element whose resistance changes when stretched or compressed.
IN ONE SENTENCE
It turns mechanical strain into a very small electrical change.
In normal English
Strain gauges are often arranged in Wheatstone bridges inside load cells, pressure sensors and structural monitoring systems.
Why would I use it?
Use it when deformation or force needs to be measured accurately.
THINK OF IT LIKE…
An electrical sticker that feels microscopic stretching.
