Temperature and health sensing is an important aspect that is required by all industries to closely monitor and prevent equipment failures and process inefficiencies. Sensors in these environments can be limited by a power source or other various conditions that can affect the material properties of conducting and resonating elements. Electroceramic materials possess some properties such as, chemical stability, high electrical conductivity and thermal protective layer that may be of interest for a passive wireless sensing unit. This work focuses on the investigation and development of far-field passive wireless sensors using electro ceramics that resonate below 4 GHz. The sensor design was modeled via Ansys HFSS and experimentally evaluated to obtain the resonant frequency, signal strength and thermomechanical properties of the system assessed under low and high temperature variations.
