WebA strain gauge (also spelled strain gage) is a device used to measure strain on an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating … WebSome metals display piezoresistivity that is much larger than the resistance change due to geometry. In platinum alloys, for instance, piezoresistivity is more than a factor of two larger, combining with the geometry effects to give a strain gauge sensitivity of up to more than three times as large than due to geometry effects alone. numbers ch1Web0. My understanding is that strain gauges are constructed using constantan etched onto a flex PCB. According to wikipedia, constantan is a highly suitable strain gauge material due to its high gauge factor. I recently came across this document which shows that copper has a higher gauge factor (2.6 compared to 2.1) than constantan. numbers cell phones
