Pyrolytic Carbon: Applications of Diamagnetic Levitation in Metrology
Résumé
This paper presents some current or potential applications in metrology implementing the diamagnetic property of pyrolytic carbon (PyC). The magnetic repulsion force acting between a piece of PyC placed in a magnetic flux density can be used as magnetic spring either to control the position of the sensitive sensor part or to detect change of a physical quantity to be measured. Several examples of PyC-based sensors are presented.
