Wearable Sensors for Flexible Health Monitoring and IoT

Abstract

This article explores the integration of advanced sensor technologies with Internet of Things (IoT) frameworks to revolutionize personal health monitoring. Wearable sensors, embedded in smart textiles or devices, provide continuous, real-time health data, enabling proactive healthcare management. This paper reviews the latest innovations in wearable sensor technology, highlighting flexible and stretchable electronics that conform to the human body, enhancing comfort and accuracy. Key developments include biosensors for tracking vital signs, chemical sensors for monitoring biochemical markers, and motion sensors for assessing physical activity. The integration of these sensors with IoT platforms facilitates seamless data transmission, storage, and analysis, offering personalized health insights and early detection of medical conditions. Challenges such as power consumption, data security, and sensor accuracy are addressed, alongside solutions involving energy harvesting, advanced encryption methods, and machine learning algorithms for data processing. The paper underscores the potential of wearable sensors in transforming healthcare delivery, reducing hospital visits, and improving patient outcomes through continuous, remote monitoring. Future directions include the development of multi-functional sensors, enhanced connectivity, and large-scale clinical validations to establish robust, user-friendly health monitoring systems.
