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.
