Video de présentationThe department originates from the creation of the Chronometry Laboratory of the University of Besançon in 1902. At that time, it devoted itself to mechanical precision watch-making and to time measurement. This laboratory led to the creation of the Chronometry Institute in 1927 which became later on the ENSI of Chronometry and Micromechanics, soon after named “ Ecole Nationale Supérieurs de Mécanique et des Microtechniques” (ENSMM).
When the laboratory was managed by J. Haag, its activities were based on mechanics (in particular on non-linear oscillation mechanics), but they were more orientated on electrical and electronic chronometry from 1930 when P. Mesnage succeeded him. Later on, the laboratory specialized in the piezoelectricity field, by resuming the quartz resonators activity of the Observatory of Paris (V.Yanouchevski) at the beginning of the sixties. Nowadays, piezoelectricity still represents the main activity of the department. In 1975, R. Besson developed the quartz resonator in technology, “BVA”, whose the short-term stability is the most perfect throughout the world.
In 2004, the LCEP laboratory joined FEMTO-ST as one of its departments and it is now managed by R. Bourquin.
