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.

Even when only analyzing 0.2 cycles, the accuracy remained strong at 85.2%. When testing with just one strain gauge, accuracy ranged between 95.2% and 98.8% with full cycle data, while it dropped ...
