I got a velostat piece and I'm trying to make a sensor pressure. Is the first time when I'm working with this material.
I'm not sure if I'm doing something wrong, or this is the expected behavior. I put a conductive thread on one side, and another conductive thread on the other side of the velostat piece. I was expecting to put some pressure over the two conductive threads in order to create a contact effect between the two threads. However, I don't put any pressure and velostat acts like a conductive textile.
Does a resistor helps? If yes, let's say that the minimum pressure I want to detect is 1kg, what resistance should have the resistor? I'm not sure that it works like that though...
