Optical fiber sensing layer and monitoring system using the same

An optical fiber sensing layer, comprising:

• two layers of pressure-sensitive assembly films which are vertically superposed and flexible;
• and
• at least one layer of flexible and smooth film which vertically separates a space between the two layers of pressure-sensitive assembly films into at least two interlayers, each interlayer is provided with at least one optical fiber row which extends along a first direction and has several S-shaped concatenated cablings, a bending portion of each cabling of the optical fiber row of the two vertically adjacent interlayers are staggered and superposed,
• wherein a luminance decay signal is generated when at least one of the optical fiber rows deforms axially, and
• an area on the pressure-sensitive assembly where the optical fiber rows are arranged forms an optical fiber sensing area, mechanical deformation of the optical fiber rows of the optical fiber sensing area and the pressure-sensitive assembly film are reflected by measuring the luminance decay signal generated by the optical fiber rows.
