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 substrate includes a thickness and a material property that are specified to ascertain, via the at least one optical fiber and for a device that is contiguously engaged with a surface of the substrate, includes the substrate embedded in the device, or includes the surface of the substrate at a predetermined distance from the device, a thermal property or a mechanical property associated with the device, or a radiation level associated with a device environment.
