What this work contributes
Demonstrates a micromachined torsional plate actuated by attraction to a nearby spherical metallic surface. The measured rotation changes with separation as predicted, connecting Casimir physics to practical mechanical components and sensors.
Where the evidence stops
The observed torque comes from a force acting through a lever arm; it differs from the orientation-dependent material torque measured in P22. The experiment does not establish continuous energy generation or whole-device thrust, and a subsequent erratum should be checked before detailed numerical reuse.
