[Prior Art] People generally think that as long as the food is still in the shelf life, it should be safe to eat, but this is not the case. For example, if the ambient temperature of the food is too high and the food is in direct contact with the air for a long time, it may cause the bacteria to multiply or the food is corrupted, which may affect human health. In order to protect consumers from eating and changing foods, many companies and academic institutions are competing to invest in the research and development of new types of foods that indicate whether foods have deteriorated. For example, Time_Temperature indicator 'TTI, whose function is to change color. Indicates the temperature and time of the product (eg, food) during storage, transportation, and sales. It can indicate the temperature change of the product from the completion of the manufacturing process to the middle of the consumer's use and the quality caused by the temperature change.
