Strain gauge on PCB

gaffatejp opened this issue · comments

It should be possible to put the strain gauge in the PCB routes. It would require small tolerances in PCB manufacturing, though. With an S-pattern on both sides of the pcb, the output would be differential, which is perfect for the Wheatstone bridge.
