However, is there a way to actually detect "where" along the strip, the pressure is applyed? I thought about solutions like IR sensors and similar but that would require additional circuitry. How would you realize this?
Do an experiment! Apply a certain amount of pressure at various places along the strip, and see if you can reliably detect a difference in the response.
of course I tried that before posting. It gives the same results no matter where you press it..I'm thinking about creating many rough pressure sensor (link) and make a new strip to be place under my force resistor strip..
? what do you mean? "of course" means that I'm not the kind of person that post here whining without even trying out things. Then do not comment unless you can give me a useful answer.
