An embedded pressure sensor was made by sandwiching a polarization maintaining photonic crystal fiber (PM-PCF) between two polymer foils. The excess birefringence induced by transverse pressure applied along the slow-axis of a PM-PCF was numerically simulated with a finite element method. Experiment was carried out with a Sagnac interferometer with the embedded PM-PCF as part of the Sagnac loop. The output interference fringes were found shift linearly with applied transverse pressure with a wavelength to pressure sensitivity of 1.764 nm/MP1 The measurement precision of 0.2%, and a dynamic range of 2.5 MPa were achieved.
