To address the limitations of existing acupoint temperature measurement

such as susceptibility to environmental interference

inability to perform dynamic monitoring

and invasive operation

a non-invasive acupoint thermometer based on T-type thermocouple has been developed. The instrument consists of multi-channel data collector

miniature thermocouple sensor

temperature-sensitive patch

and Toprie data processing software

offering the advantages including long-term dynamic monitoring of multiple acupoints

stable

rapid and accurate data acquisition

non-invasive portability

and ease of operation. Based on the Seebeck effect

the instrument uses a T-type thermocouple with the diameter ≤1 mm and thermal equilibrium time ≤1 s as the temperature sensing element. It enables long-term dynamic monitoring of multiple acupoints

thereby providing the objective quantitative data for diagnosis of traditional Chinese medicine. With the aid of miniaturization and wireless transmission technologies

the instrument is expected to be extended to clinical application scenarios such as chronic disease management

sports medicine monitoring

and health intervention of"preventive treatment of disease" in traditional Chinese medicine.
