Multicore optical fibre can be used to implement multidimensional optical fibre sensors. In this paper, an array of four multiplexed FBGs is inscribed in a multicore optical fibre in order to obtain a multipoint curvature sensor. An improved FBG inscription technique is used in order to mitigate the several issues that arise during the inscription of FBGs in this kind of optical fibres. The optical fibre sensor is described and theoretically analysed in order to obtain the magnitude and direction of the curvature and also the strain produced by external forces.
