What type of metal rod/strip could I insert in a pad that could then

Just design it so that stress stays elastic..
After that take cyclic fatigue into consideraton..

Some spring steel flat might be a good start..

Thanks...
Would spring steel hold its shape in order to hold the pad on my knee
until I wanted to unbend it to take it off?

There is no metal that will do this forever. *But soft aluminum wire is
pretty good, and cheap. *Art stores sell such wire for use as armatures
in plaster sculpture.

Black or galvanized iron wire is also pretty good, in the thicker
grades. *McMaster-Carr is a good source.

You will also need wirecutting pliers and a file (to smooth the cut ends
of the wire).
