In this paper we will discuss a new type of long period grating (LPG) that consists on an optical
fibre glued on top of a 3D printed grooved plate. The LPG performance will be tested for the case when
pressure is applied transversely to the grooved plate. Results showed the appearance of attenuation bands at
specific wavelengths, that grow with increasing load. The evolution of the dip power at those resonances, as
function of the curvature will be shown, demonstrating the potentialities of the sensor for low cost intensity
detection schemes.
