I am trying to design something that will sense how much of a movement a certain part of the body makes (such as jaw), but I'm not sure what would be the best method.
One method is using video camera and image processing, but it might not be as sensitive as I would like.
Another one has 2 surfaces connected by a light spring. One is connected to the jaw and is move-able while the other one is static. Both have a wires attached to them. One of the wires has AC current running through it which produces current (magnetic induction) in the other wire. Because of the jaw movement, the distance between cables will change which will cause a changed in the current in one of the wires that can be detected by a signal analyzer.
Any better suggestions or comments?
