Environmental Sensor System
First Claim
1. A method to detect one or more environmental conditions in proximity to a surface, comprising:
- activating 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;
orthe presence of a chemical or biological agent proximate the sensor module;
generating, in the environmental sensor module, an electromagnetic signal which comprises information about the resonance frequency;
receiving, in a remote receiver, the electromagnetic signal comprising the signal generated by the environmental sensor module; and
determining an environmental condition from the electromagnetic signal.

Abstract
In one embodiment, a system to detect one or more environmental conditions in proximity to a surface comprises a first metamaterial environmental sensor module proximate the surface. 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. The system further comprises 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 such as humidity, temperature, pre-ice conditions, ice, chemicals or biological species from the at least one environmental condition signal. Other embodiments may be described.
