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 ...
Fig 1. The MEMS pressure sensor detects the tensile stress on a thin silicon membrane that changes the piezo-resistance of elements on the membrane’s surface. Fig 2. The MEMS sensor’s piezo-resistive ...
