ABRUPT METAL-INSULATOR TRANSITION(MIT) DEVICE, MIT SENSOR USING THE SAME ABRUPT MIT DEVICE, AND ALARMING APPARATUS AND SECONDARY BATTERY ANTI-EXPLOSION CIRCUIT COMPRISING THE SAME MIT SENSOR

摘要

A rapid MIT(Metal-Insulator Transition) device, a MIT sensor using the device, and an alarm and a secondary battery explosion preventing circuit including the MIT sensor are provided to vary a transition temperature by changing an applied voltage or current. An MIT(Metal-Insulator Transition) thin film(300a) generates the rapid MIT at a transition temperature or a transition voltage. At least two electrode thin films(410a,420a) are comprised to be contacted to the rapid MIT thin film. A transition temperature and a transition voltage of the MIT device is changed by a temperature, a microwave, a pressure, a gas concentration or a voltage which is added to the electrode thin films.
