摘要： A fiber optic sensor comprising a fiber optic (203) having two operatively connected and parallel arms (205,206), each arm having a Bragg grating (204). The fiber optic is embedded between a plurality of embedding layers. The embedding layers comprise an upper portion (210) with at least one upper layer and a lower portion with at least one lower layer. The arms (205,206) are operatively connected by an arcuate portion (207). There is at least one embedding layer (201) between the first arm (205) and the second arm (206). The sensor is not affected by temperature and may be able to read temperature, or expansion/contraction due to temperature.

摘要： In this invention, a bending sensor arrangement (2) for sensing at least one force (4) comprises of at least two fiber Bragg grating (FBG) sensors (12) attached at substantially perpendicular axes to each other on a surface of a longitudinal member. The bending sensor arrangement (2) also includes a first system and a second system. The first system measures and interprets Bragg wavelength information from the at least two FBG sensors (12) respectively. The second system serves to provide user friendly data viewing of the results obtained from the first system. As mentioned earlier, the force (4) is exerted upon the longitudinal member causing the FBG sensors (12) to experience strain whereby said strain is detected by the first system. This first system measures, interprets and relates the Bragg wavelength information to determine the direction of the force (4) and the spatial displacement of the longitudinal member about a fixed end. This information is then processed and displayed by the second system in a user friendly format.
