Abstract

A multilayer material is described herein that includes at least one signaling layer configured to propagate at least one electromagnetic signal; and a flexible layer configured to enclose the at least one signaling layer, wherein the flexible layer is substantially impermeable to an environment and to the at least one electromagnetic signal. The multilayer material including the at least one signaling layer is configured to transmit a change in the at least one electromagnetic signal upon exposure of the signaling layer to the environment. A system, an article of clothing, or a method is described herein.
