We have demonstrated pressure sensing focusing on the transmitted light power change near the Bragg wavelength by using FBGs drawn by plane-by-plane method on PFGI-POF. In particular, a remarkable spectral change was observed only when pressure was applied directly above the FBG, indicating the possibility of application to a point-type pressure sensor.
