underlying physical mechanisms are explained. The spectral and directional sensitivity of a coated PVDF film are significantly … different from that of an uncoated PVDF film, and this can be explained by the amplification of the in-plane stress component by … thickness of the coating material. The sensitivity of the coated PVDF film below the first resonance frequency, owing to the …
