I'd like to measure the force that a human leg impacts on a knee brace during normal gait. I have a problem in finding a suitable sensor for the job...
The leg (and hence the brace) are not flat at their contact surface and it seems FSRs change their response dramatically when bent... and load cells seem quite bulky and also have the same restriction.
I looked at more exotic solutions, e.g. Creating my own sensor out of Velostat (http://www.robotshop.com/uk/pressure-sensitive-conductive-sheet-velostat-linqstat.html) but my concern is it won't be accurate or reliable.
Can strain sensors give me low creep and good repeatability?
