Provided are an abrupt MIT device with variable MIT temperature or voltage, an MIT sensor using the abrupt MIT device, and an alarm apparatus and a secondary battery anti-explosion circuit including the MIT sensor. The MIT device includes an abrupt MIT layer undergoing an abrupt MIT at a transition temperature or a transition voltage and at least two electrode layers contacting the abrupt MIT layer. The transition temperature or the transition voltage varies with at least one of factors including a voltage applied to the electrode layers, a temperature, an electromagnetic wave, a pressure, and a gas concentration that affect the abrupt MIT layer. The MIT sensor is a temperature sensor, an infrared sensor, an image sensor, a pressure sensor, a gas-concentration sensor, or a switch. The alarm apparatus includes the MIT sensor and an alarm-signaling unit connected in series with the MIT sensor. The secondary battery anti-explosion circuit includes a secondary battery, the MIT sensor attached to the secondary battery to sense the temperature of the secondary battery and thus to prevent the possible explosion of the secondary battery, and a protection circuit body powered by the secondary battery.
