This video explores the fascinating world of strain gauges, these clever little devices that combine elements of mechanical engineering, electrical engineering, and materials science to give us a way ...

[Curious Scientist] tried building an integrated strain gauge on a PCB, but ran into problems. Mainly, the low resistance of the traces didn’t show enough change under strain to measure easily.

Here’s a neat trick for your next 3D-printer build or retrofit: a Z-axis sensor using a DIY strain gauge made from SMD resistors. We’re betting it could have plenty of other applications ...
