Abstract: In the present investigation, praseodymium oxide (Pr 2 O 3 ) nanoparticles embedded polyvinylidene fluoride (PVDF) thick films were fabricated via solution casting/intercalation technique. The Pr 2 O 3 nanoparticles were synthesized by the hydrothermal technique. The Fourier Transform Infrared Spectroscopy (FTIR) has been recorded in the range 400 to 4000 cm -1 , and functional groups were identified in the nanocomposite films. Infrared vibrational spectroscopy (FTIR and Raman) curves revealed ferroelectric ß-phase in the annealed nanocomposite films intrinsically. The electrode films so produced were sandwiched between Kapton film to form a sensing device. Based on reasonable linear piezo-capacitive behaviors obtained, PVDF-Pr 2 O 3 nanocomposites films can be used to create highly flexible pressure sensors.
