Hi guys,
I wanted to design a system that would be able to detect the movement on my finger. I only need it to be able to detect the "bending" of my finger ( joint in th emiddle of my finger ) as well as at my knuckle.
I was thinking of having a rigid mechanical system where I could place my finger into , and have potentionmeters at the joints connected to a voltage divider circuit, which would therefore give different voltages for different "angles" and use that along with a lookup table of some sort to identify the fingers position.
My question is whether or not I will get significant voltages changes when I alter the angle of rigid system, and what are the ways to get maximum change in voltage per angle change in the potentionmeter ( eg: high resistance values, larger voltage source , etc etc )
I also wanted to know if there are other ways of detecting such a motion, note that I will be extending this idea for all 4 fingers.
Any if there are any mechanical dudes out there , is there a way to keep the rigid system from " collapsing" at the joints but still be able to move it light force by my finger?
Thanks guys
