Flexible Sensors for IoT-Based Health Monitoring

The global population is aging due to increased life expectancy and declining birth rates. As a result, there is a growing prevalence of chronic diseases such as heart disease, hypertension, and diabetes, among the older population. These conditions not only diminish the quality of life but also significantly drive up healthcare costs. Consequently, the demand for efficient and cost-effective healthcare solutions is rising. Traditional healthcare systems are often challenged by issues of accessibility and equity, particularly in regions with inadequate medical infrastructure and geographic barriers. In response to these challenges, this article explores the potential of advanced flexible sensor technologies, integrated with cutting-edge communication and computing tools such as the Internet of Things (IoT), artificial intelligence (AI), and big data analytics. These sensors enable continuous, unobtrusive monitoring of vital signs, and health parameters, facilitating personalized and preventive care in the comfort of an individual’s home. However, the widespread adoption of these technologies faces several obstacles, including challenges related to manufacturing scalability, cost, mechanical stability, and data security. This article reviews the current state of research and development in flexible sensors and their integration with modern technologies for IoT-based health monitoring. It also examines key challenges and concerns associated with their use and outlines the future potential for these sensors to revolutionize healthcare monitoring and management.
