Abstract

Wearable biosensors have emerged as a transformative technology in healthcare, enabling real-time monitoring of physiological parameters. These devices offer unprecedented opportunities for early disease detection, personalized medicine, and continuous health tracking. However, the widespread adoption of wearable biosensors is hindered by several challenges, including technical limitations, data privacy concerns, and regulatory hurdles. This article provides a comprehensive review of the current state of wearable biosensors, exploring their materials, methods, and applications. We also discuss the opportunities and challenges associated with their use in real-time health monitoring, offering insights into future directions for research and development.
