Abstract
Provided are a temperature sensor using a metal-insulator transition (MIT) device subject to abrupt MIT at a specific temperature and an alarm including the temperature sensor. The abrupt MIT device includes an abrupt MIT thin film and at least two electrode thin films that contacts the abrupt MIT thin film. The abrupt MIT device generates abrupt metal-insulator transition at a specific transition temperature. The alarm includes a temperature sensor comprising an abrupt MIT device, and an alarm signaling device serially connected to the temperature sensor. Accordingly, the alarm can be manufactured to have a simple circuit and be of a small size by including the temperature sensor using an abrupt MIT device.
