Abstract:

In order to realize real-time monitoring of human skin temperature, this research aims to create temperature-sensitive garment with a full fabric sensing network, making use of the differences in skin temperature distribution of different parts of the human body and the requirements for repeatability and comfort of temperature-sensitive clothing, on the basis of in-depth study of existing monitoring techniques. The array arrangement model of regional sensor network and the design method of data acquisition and storage system finally prepare the temperature-sensitive clothing based on the full fabric sensing network. It is proved that the whole fabric temperature-sensing network offers high stability after tensile recovery of the fabric. By testing the temperature sensitivity of temperature-sensitive clothing and evaluating its repeatability and comfort, it demonstrated high sensitivity and good practicability. The portable data acquisition and storage system was developed through comprehensive comparison of practicability between different data acquisition modules. Finally, combined with the data acquisition system, monitoring of the human skin temperature is succeeded in real time using the temperature sensitive clothing. It is proved that the breathing state of the human body can be tracked through the curve of the human body temperature, and the comfort requirement is satisfied.
