Application of Vanadium Dioxide for Thermal Sensing

Thermal sensors are widely used in different areas such as, automotive, defense, healthcare, and fire protection. Heat management is a hot topic nowadays, especially in electronics and power electronic packages, due to the miniaturization of semiconductor devices dimensions. New materials and concepts are studied to develop thermal sensors with more excellent reliability and sensitivity. Vanadium dioxide is a strongly correlated electron material with interesting thermal and optical properties due to its transition from a low-conducting phase to a high-conducting phase called metal-to-insulator transition. This study investigates two different models to use vanadium dioxide as a sensing element by presenting simulations performed on SUNRED simulator.
