摘要： 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, wherein the optical fiber is connected to a reference body and to the transmission structure with first and second connecting parts, the first and second connecting parts 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 inbetween a negative stiffness range around an unstable equilibrium position, and wherein the optical fiber is pre-stressed thereby acting as a spring having a first spring constant of positive value to counteract a spring action of the bi-stable spring.

摘要： The invention relates to an optical sensor device comprising a reference body and at least one sensing transducer. The sensing transducer is arranged for moving relative to the reference body in response to an input action. The device further comprises an optical fiber and one or more transmission arms. The optical fiber comprises an intrinsic fiber optic sensor and is connected with a first connecting part to a first transmission arm and with a second connecting part to an element exterior to the first transmission arm. The first and second connecting parts are on either side of the intrinsic fiber optic sensor. A base of the first transmission arm is connected at a first part with the reference body and with a second part with the sensing transducer. The optical fiber is connected at a location along the first transmission arm remote from the base.

摘要： The invention relates to an optical sensor device comprising a reference body, an optical fiber including an intrinsic fiber optic sensor, and a hydraulic transmission system. The hydraulic transmission system is connected to the reference body such that an input portion and an output portion are movable with respect to the reference body. The optical fiber is connected with a first connecting portion to the output portion of the hydraulic transmission system and with a second connecting portion to an element exterior to the hydraulic transmission system. The intrinsic sensor is positioned between the first and second connecting portion. The input portion is arranged for receiving an input action and the hydraulic transmission system is arranged for converting the input action to a sensing action applied to the optical fiber by the output portion such as to modify strain in the optical fiber dependent on said input action.
