Research Progress of Flexible Wearable Sweat Sensors Based on Microchannel Design

In recent years, with the development of flexible electronics and microfluids, various flexible wearable sweat sensors based on microchannel have been developed, and exhibit excellent development prospect. In this paper, the advantages of flexible wearable sensors based on microchannel design for sweat detection were introduced, and the research progress of the principles of structural design, detection methods and microchannel sweat detection sensors was summarized. The deficiencies and limitations of microchannel sweat sensors were analyzed. The review pointed out that the sweat sensors based on microfluidic channel design should be developed in the direction of low cost and mass production, and it was important to further study the relationship between sweat parameters and human physiological health.
