Investigating pomegranate rind dye for wearable health monitoring: a colorimetric approach to analyzing sweat, glucose, and insulin

Abstract

This study investigates the potential of pomegranate rind dye, a natural source of pH-sensitive anthocyanins, in the field of health monitoring through the colorimetric detection of sweat analytes, markers of physiological states [1], [2]. Addressing the limitations of cost and complexity inherent in traditional sweat analysis methods prevalent in healthcare and sports science [2], [3], our approach utilizes colorimetric analysis. This technique, simpler and more cost-effective, relies on visual color changes in response to specific analytes for quantitative data acquisition [1]. Emphasizing sustainability and economic feasibility, our research highlights the potential of natural dyes, particularly pomegranate rind, in creating eco-friendly, cost-efficient textile-based indicators for health monitoring applications, including fertility and menstrual cycle tracking.
