<p>The present invention relates to a sensor for detecting the degree of exposure to heat and, more specifically, to a sensor for detecting heat exposure, which can detect the degree of exposure to heat by using the orientation state of a liquid crystal device changed due to exposure to heat. According to the present invention, the degree of temperature variation can be provided when being distributed and stored, by checking the sensor for detecting heat exposure by using a liquid crystal having the orientation state changed by heat.</p> |
