In this work is reported the bending sensing characteristics of a long-period grating produced point-by-point with a
266 nm Nd:YAG laser. Spectral changes of the transducer subjected to bends with curvatures from 0 to 3.13 m<sup>-1</sup> were
investigated. The magnitude of the bend-induced wavelength shift is nonlinear and dependent on the rotation of the
cylindrical fibre relative to the bending plane. For each constant bending applied to the grating, the fibre was rotated
around its axis in angular steps of 15º, within the angular range from 0 to 180º. An artificial neural network model was
applied for identifying the curvatures, resulting in a root-mean-square error of 0.028 m<sup>-1</sup>.
