“…Sweat detection plays an important role in the non-invasive testing of human bodily fluids because to the balance between comfort and continuous sample collection. − For example, in babies, the concentration of chloride in sweat correlates with cystic fibrosis . In addition to the electrolyte content in sweat, lactate is recognized as a critical biomarker since its content in humans has direct connection with acidosis, dehydration, and electrolyte metabolism issues. , As a result, creating wearable sweat lactate sensors has a lot of promise for measuring people’s health. ,, Because of intuitive sensing in the colorimetric approaches, semiquantitative detection of sweat lactate has been incorporated into a textile-based sensor . However, its precision is easily impacted by external ambient light and has low consistency, limiting its practical applicability. , Furthermore, the strength of the colorimetric signal is affected not only by sample concentration but also by sample volume.…”
