Abstract
An optical fiber-based sensing membrane includes at least one optical fiber and a substrate. The at least one optical fiber is integrated in the substrate. The optical fiber-based sensing membrane includes, based on a specified geometric pattern of the at least one optical fiber, an optical fiber-based sensing membrane layout. The substrate includes a thickness and a material property that are specified to ascertain, via the at least one optical fiber and based on the optical fiber-based sensing membrane layout, a thermal property or a mechanical property associated with a device, or a radiation level associated with a device environment.

An optical fiber-based sensing membrane comprising:
- a substrate;
- and
- at least one optical fiber integrated in the substrate,
- wherein the at least one optical fiber is placed on the substrate in a pattern that includes arbitrary paths and common paths, wherein the arbitrary paths are paths where the at least one optical fiber is arbitrarily placed on the substrate, and the common paths are paths where one end of the at least one optical fiber is looped back to join another part of the at least one optical fiber, and
- wherein the common paths of the at least one optical fiber are evenly distributed over a total length of the at least one optical fiber to provide temperature measurements of a device.
A method for forming an optical fiber-based sensing membrane comprising:
- placing at least one optical fiber on a substrate in a pattern that includes arbitrary paths and common paths, wherein the arbitrary paths are paths where the at least one optical fiber is arbitrarily placed on the substrate, and the common paths are paths where one end of the at least one optical fiber is looped back to join another part of the at least one optical fiber, and wherein the common paths are to be evenly distributed over a total length of the at least one optical fiber;
- rolling a consolidation roller on the substrate to uniformly press the at least one optical fiber in the pattern onto the substrate;
