Another area you might consider is using simple inductors. A system
which has as much resolution as you'd care to spend on it. The
tecnique being to place an inductor on one section of the joint and
a moving "core" (in the form of a conductive wire) on the other
section. Energizing the inductor and then measuring the emf generated
in the core. Note I've never actually implemented one of these so
I don't have complete confidence in its viability but I don't see
any obvious flaws in it.

These opinions are my own and no one elses, but you knew that didn't you.
