Abstract

The invention discloses a flexible temperature-sensitive sensor. The flexible temperature-sensitive sensor comprises a flexible substrate, a temperature-sensitive material layer, an electrode layer and a flexible protection layer, wherein the temperature-sensitive material layer is formed on the surface of the flexible substrate and provided with a three-dimensional porous nano-structure; the electrode layer comprises at least two electrodes, and the electrodes are led out from the temperature-sensitive material layer or the surface of the temperature-sensitive material layer; the flexible protection layer is formed on the surface of the temperature-sensitive material layer or the surface of the temperature-sensitive material layer and the portion of the electrode layer, on the surface of the temperature-sensitive material layer. The invention further discloses a body temperature monitoring system based on the flexible temperature-sensitive sensor. The sensor disclosed by the invention is light, thin and soft, capable of being machined into various shapes, and capable of being attached and worn on the surface of the skin as clothes; the sensor and the monitoring system have the advantages of being high in sensitivity, simple to operate, non-invasive, accurate in measurement result, and capable of continuously recording body temperature changes.

Description

technical field [0001] The invention relates to the field of body temperature monitoring, in particular to a flexible temperature sensitive sensor and a body temperature monitoring system based on the sensor. Background technique [0002] Body temperature refers to the average temperature inside the body, which is maintained by the chemical energy released by the metabolism of nutrients in the body. As an important physiological sign parameter, body temperature plays an important role in clinical practice. Since fever is the prodromal symptom of many diseases, changes in body temperature are also one of the criteria for the diagnosis of many diseases. In addition, body temperature is also closely related to women's menstrual cycle, so accurate and effective monitoring of body temperature is very important in the field of public health, especially in disease prevention and control. [0003] At present, the most commonly used clinical temperature monitor is a mercury thermom...
