An Intelligent Wristband for Simultaneous Multiparameter Measurement during Fumigation and Washing Therapy of Traditional Chinese Medicine.

Traditional Chinese medicine (TCM) is one of the oldest healing systems, which plays an essential role in daily health management. However, TCM is frequently controversial due to its subjectivity and lack of scientific quantification. Modern sensing technologies, enabling the detection of various physiological signals, have the remarkable performance of multifunctionality, superintegration, and ultraminiaturization. Combining with modern sensing technology is a good opportunity for the modernization, objectification, and scientization of TCM. This article proposes an intelligent wristband for simultaneous multiparameter measurement of pulse, skin temperature, and perspiration, essential physiological signals in TCM. As a significant functional material, a carbon nanotube/poly(dimethylsiloxane) nanocomposite with 3D interpenetrating network structures exhibits great electrical conductivity, stress effect, and thermoresistive effect, ensuring intelligent wristband's high accuracy, high sensitivity, and good stability for pulse and temperature measurements. Furthermore, the perspiration sensing unit is also integrated. The as‐prepared intelligent wristband is applied during fumigation and washing therapy, and artificial intelligence is introduced to judge whether the user is during fumigation and washing therapy or in the resting state by classifying the user's physiological state, with an accuracy of up to 100%. This work offers a unique strategy for TCM and wearable sensing technology with an important practical significance.
