We investigated the sensing properties of a single mode Poly Methyl Methacrylate (PMMA) Microstructured Polymer Optical Fibre (MPOF) with mechanically imprinted Long Period Grating (LPG). We measured the influence of strain to the LPG wavelength which showed the viscoelastic nature of PMMA. We also measured the influence of temperature and humidity to the LPG wavelength.
