1. An optical fiber-based sensing membrane comprising:
an optical fiber; and
a substrate, wherein the optical fiber is integrated in the substrate in a pattern of a plurality of coils,
wherein to form the pattern of the plurality of coils, the optical fiber is placed on the substrate in a first circular shape multiple times to form a first coil, and continues to be placed in a second circular shape multiple times to form a second coil, and
after the second coil is formed, the optical fiber is folded back onto a common path with the first coil, wherein the common path enables the optical fiber-based sensing membrane to provide accurate temperature measurements of a device.
