Intrinsic sensors utilize a change that takes place within the fiber itself. This is in contrast to extrinsic sensors, in which the change is outside the fiber and the fiber itself remains unchanged. An example is a pressure sensor based on microbending of the fiber. A fiber is placed between two plates with rough surfaces.
