1. A leak-and-sealing-failure-detection sensor contained within a global gaseous or liquid environment having one or more chemical components, the leak-and-sealing-failure-detection sensor comprising:
an interrogation component that emits an interrogation signal;
a monitoring component that outputs an indication of a leak or sealing failure when the monitoring component detects a response signal; and
a sensor substrate impregnated with reporter molecules that
receives the interrogation signal, and
when the concentration of at least one of the chemical components in a local environment containing a portion of the sensor substrate differs from the concentration of the chemical component in the global environment, the portion of the sensor substrate emits a response signal to the monitoring component.
