Abstract
Provided are a circuit for continuously measuring a discontinuous metal-insulator transition (MIT) of an MIT element and an MIT sensor using the circuit. The circuit comprises a to-be-measured object unit including the MIT element having a discontinuous MIT occurring at the transition voltage thereof, a power supply unit applying a predetermined pulse current or voltage signal to the to-be-measured object unit, a measurement unit measuring the discontinuous MIT of the MIT element, and a microprocessor controlling the power supply unit and the measurement unit. The discontinuous MIT measurement circuit continuously measures the discontinuous MIT of the MIT element, and thus it can be used as a sensor for sensing a variation in an external factor.
