Sweat Biosensors for Health and Wellness: A Comprehensive Review of Recent Developments

Abstract

A promising non-invasive diagnostic technique, sweat-based biosensing provides real-time monitoring of important indicators linked to disease, stress, hydration, and metabolic health. Sweat biosensors, which use wearable technology, offer a continuous and painless alternative to conventional blood-based testing for physiological evaluation. With a focus on developments in electrochemical, optical, colorimetric, and microfluidic sensors, this overview examines the development of sweat biosensing technologies. It talks about how to improve sensor accuracy and usefulness by combining wireless data transmission, artificial intelligence, and multi-analyte detection methods. The study looks at the various uses of sweat biosensors in sports science, mental health monitoring, and personalized medicine. Clinical adoption is still significantly hampered by issues including sweat rate fluctuation, sensor calibration, and ambient factors, despite their potential. For the next generation of wearable biosensors, future research will concentrate on enhancing sensor stability, data processing algorithms, and sustainable materials. The goal of this thorough analysis is to shed light on the most recent developments, emerging trends, and potential applications of sweat-based biosensing in biomedical research and customized healthcare
