Optical fiber-based sensing membrane layout

A method comprising:

• embedding an optical fiber-based sensing membrane in a device or contiguously engaging the optical fiber-based sensing membrane with the device, wherein the optical fiber-based sensing membrane includes:
• at least one optical fiber;
• and
• a substrate, wherein
• 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, and
• the substrate includes a thickness and a material property;
• and
• ascertaining, via the embedded or the contiguously-engaged optical fiber-based sensing membrane, a thermal or a mechanical property associated with the device,
• wherein the specified geometric pattern of the at least one optical fiber includes a spiral geometric pattern, and
• wherein each spiral of the spiral geometric pattern includes no direct neighbor, and wherein the spiral geometric pattern is associated with a particular spatial key that is used to detect sidelobes in a first and a second dimension.
