Oh for sure, it’s relative to the system being harvested from and the amount of energy being extracted though. If it’s a train cart/carriage then not really a problem as there is so much mass and vibration to go around, if it’s the surface of a small industrial machine that needs to be reasonably balanced only producing a few hundred milli g then more of a concern.
