Abstract

A physical sensor comprising a substrate, a movable mass, said mass being able to be moved by an external force, a first optical resonator, a light wave guide for measurement and a light wave guide for detection, a rigid plate which are able to modify the optical resonance frequency of said optical resonator by moving closer and away the same, a lever arm rotatably hinged to the substrate by a pivot connection and the mass being movably integral with the transmitting means, the rigid plate being disposed relative to the mass and to the pivot connection such that the lever arm transmits to the rigid plate, in an amplified manner, the displacement of the mass.
