Finger position sensor

Hello,

I am developing a glove project was wondering if anyone could answer my questions please.

1) If i am using peizos on each of my 10 fingers, is there any cheapish sensors that can detect how far each finger is from each other? e.g. if my index finger has pressed a position, when i press my middle finger it can tell if it was pressed 2cm's away?

Also if i press with my middle finger on my right hand, can i press on my middle finger on my left hand 40cm's away and it be measured?

Thank you
