Artificial external muscle strap
  (+3)

Over the kneecap is a protective layer that allows a strap to pull over it, enhancing the quadriceps muscle contraction, pushing the leg out.

The small motors sit on the strap itself, causing the strap to become a sort of external artificial muscle.

The contraction starts when you start pushing your leg out. and stops at a given maximum. This can easily be adjusted by changing the length of the strap.

       [a1] that link is interesting: there are no photos of anyone actually wearing/using the completed device. Maybe they ran out of funds?

       That was one link of many I found on powered assists. Which is not to say pashute’s concept of “motor in the strap” has been done, just that there’s been some work on the overall concept.
