    We demonstrate a chirped microstructured polymer fiber Bragg grating based on taper technology for strain
    sensing application. The effective bandwidth of the grating is dependent on strain and remains practically
    constant with respect to temperature and humidity changes. We report a sensitivity of 0.90 pm/µε for the central
    wavelength under stable temperature and humidity values. The 3-dB bandwidth of the grating has been measured
    under different temperature and humidity conditions.
