| Abstract Scope |
The main object of this work focused on analyzing the stability and performance of various electroceramic oxides for the fabrication of LC-based RFID tags to wirelessly monitor the health of a high temperature system. The electroceramic materials were evaluated based on their operating temperature regime, electrical conductivity, thermal, and microstructural/chemical stability. The RFID tags were fabricated by depositing the electroceramic materials on polycrystalline alumina substrates by a novel microcasting technique. The parameters contributing to the wireless response such as the geometric form-factor, the distance between the sensor and the interrogator antenna, and environmental effects were evaluated in a realistic working environment of the sensor. The material characterization of the electroceramic materials and the sensors were performed by scanning electron microscopy, 4-point conductivity, impedance spectroscopy, and X-ray diffraction. The wireless response of the LC resonator was characterized by a multimode user-defined software radio which acts as a signal transmitter and receiver. |
