Abstract: The invention is directed at an optical sensor device, comprising a sensing element for receiving an input action, an optical fiber comprising an intrinsic fiber optic sensor, and a transmission structure arranged for exerting a sensing action on the optical fiber in response to the input action received by the sensing element, wherein the optical fiber in a first connecting part thereof is connected to a reference body and wherein the optical fiber in a second connecting part thereof is to the transmission structure for receiving the sensing action, the first connecting part and the second connecting part of the optical fiber being located on either side of the intrinsic fiber optic sensor, wherein the transmission structure comprises a bi-stable spring having a first and a second stable deflection position and a negative stiffness range around an unstable equilibrium position between the first and second stable deflection position, and wherein the optical fiber between the transmission structure and the reference body is pre-stressed such as to be tensed, said optical fiber thereby acting as a spring having a first spring constant of positive value, wherein the optical fiber thereby counteracts a spring action of the bi-stable spring such as to operate the bi-stable spring in a deflection position range within the negative stiffness range, the deflection position range not including the unstable equilibrium position of the bi-stable spring.

Abstract: An optical pressure sensor device (1) comprises: a chamber (2) filled with pressure transfer medium and having at least one window (4) transparent to pressure waves; an optical fibre (7) with a Fibre Bragg Grating (8); a first pressure-sensitive mounting assembly (100) arranged within the chamber, holding the optical fibre; a second pressure-sensitive mounting assembly (200) arranged within the chamber, holding the optical fibre. The first pressure-sensitive mounting assembly, the second pressure-elm.) sensitive mounting assembly, and a static pressure compensation assembly (300) comprise pairs of bellows arranged on opposite sides of the fibre (7). The bellows (310, 320) of the static pressure compensation assembly have their interior in fluid communication with the pressure transfer medium in the chamber via a choke channel (314, 324), and have very low static stiffness.

Abstract: The invention relates to an optical sensor device comprising a reference body and at least one sensing transducer. The sensing transducer is arranged for receiving an input action, and is movably arranged relative to the reference body for moving relative to the reference body in response to the input action. The device further comprises an optical fiber and one or more transmission arms including a first transmission arm. The optical fiber comprises an intrinsic fiber optic sensor. The optical fiber is connected with a first connecting part thereof to the first transmission arm and with a second connecting part thereof to an element exterior to said first transmission arm. The first connecting part and the second connecting part are on either side of the intrinsic fiber optic sensor. For receiving the input action, a base of the first transmission arm is connected at a first part thereof with the reference body and with a second part thereof with the sensing transducer. The optical fiber is connected at a location along the first transmission arm remote from the base thereby converting the input action received by the sensing transducer into a sensing action applied to the optical fiber such as to modify strain in the optical fiber dependent on said input action.
