Wireless Temperature Measurement System And Methods Of Making And Using Same
First Claim
1. A method of fabricating a temperature measurement device, the method comprising:
- depositing a dielectric material having temperature-dependent electrical properties;
disposing an antenna at least partially within the dielectric material, the antenna having a resonant frequency that varies in response to temperature-dependent characteristics of the dielectric material, the antenna configured to receive a RF signal; and
providing a diode in communication with the antenna and configured to produce a harmonic of the RF signal in response to receipt of the RF signal.

Abstract
A temperature measurement system capable of operating in harsh environments including a temperature sensor having an antenna, diode, and dielectric layer disposed on the object of interest is provided, wherein the antenna includes a buried portion that extends through and is electrically coupled to the object of interest, and an exposed portion disposed upon an outer surface of the dielectric layer and the diode is coupled between the object of interest and the exposed portion of the antenna. The antenna is configured to receive interrogating signals from a transmitter, and to transmit response signals corresponding to the resonant frequency of the temperature sensor and its harmonics, which are indicative of the measured temperature of the object of interest. A receiver detects the response signals and correlates the frequency to a known temperature response of the dielectric material. Methods of making and using the temperature measurement system are also provided.
