I can't see where I have provoked such a defensive response.

The lack of any real response to your question is notable.
Part of the problematical lack of response is that

"... A piezo sensor is probably an acellerometer. A
sensing coil produces velocity feedback. Either can be
turned into positional feedback with appropriate
circuitry (one or two stages of electronic mathematical
integration). ..."

is literally incorrect. No translation is possible.
Acceleration cannot be mapped into position, and it's
not done that way.

Your questions are always interesting; don't stop.
Much thanks, as always,
