Hey, I need some help for my sensing coursework. I have decided to make a strain gauge to measure the weight of items. I was wondering is there any formulae which relates the output voltage and the load? Or resistance? Any formulae I can use except resistance= resistivity x length/area, the gauge factor or any basic formulae (such as R=V/I etc). Any help would be greatly appreciated.
