Environmental Sensor System

A system to detect one or more environmental conditions in proximity to a surface, comprising:

• an environmental sensor module proximate the surface, wherein the environmental sensor comprises a metamaterial-based electrically resonant structure having a resonance frequency which varies in response to changes in at least one of:
• a humidity proximate the sensor module;
• a temperature proximate the sensor module;
• or
• the presence of a chemical or biological agent proximate the sensor module;
• a remote receiver to receive an electromagnetic signal comprising the signal generated by the electrically resonant structure;
• and
• a signal analysis module to determine an environmental condition from the at least one environmental condition signal.

An aircraft, comprising:

• a fuselage;
• and
• a system to detect one or more environmental conditions in proximity to a surface of the fuselage, comprising:
• an environmental sensor module proximate the surface, wherein the environmental sensor comprises a metamaterial-based electrically resonant structure having a resonance frequency which varies in response to changes in at least one of:
• a humidity proximate the sensor module;
• a temperature proximate the sensor module;
• or
• the presence of a chemical or biological agent proximate the sensor module;
• a remote receiver to receive an electromagnetic signal comprising the signal generated by the electrically resonant structure;
• and
• a signal analysis module to determine an environmental condition from the at least one environmental condition signal.
