Methods and systems for passive, wireless temperature monitoring

A method for monitoring temperature at individual locations across a structure, said method comprising:

• deploying an interconnected array of temperature dependent sensors at the individual locations;
• exciting the array of sensors from at least one end of the array;
• determining a resonant frequency for each sensor in the array of sensors using a converging simulated mathematical model of the array of sensors;
• and
• generating a spatial temperature map for the structure based on the resonant frequency of the individual sensors in the array of sensors.

A system for monitoring temperature at a plurality of locations, said system comprising:

• an interconnected array of temperature dependent capacitive devices;
• at least one source for exciting said interconnected array;
• at least one receiver configured to determine a resonant frequency of said interconnected array;
• and
• a processing device, said processing device programmed to determine a resonant frequency for each temperature dependent capacitive device using a converging simulated mathematical model of the interconnected array and generate a spatial temperature map for the plurality of locations based on the resonant frequency of the individual temperature dependent capacitive devices.
