Abstract
En 中文
Wearable biosensors have revolutionised the field of healthcare monitoring and sweat-based wearable biosensors are a significant game changer due to the benefits of label-free detection, rapid response and ease of integration. At a high level, they offer a new way to monitor health metrics. In this review, we focus on sweatbased wearable biosensors (SBWSs) and their applications in healthcare monitoring. In this study, we categorise these sensors' structural and functional properties into several types, such as enzyme-based, antibody-based, aptamer-based and ion-sensitive membrane-based. This study offers a comprehensive understanding of how sweat-based biosensors work and how they can be employed in healthcare monitoring. We further focus on the challenges and prospects of SBWSs from the perspective of technological limitations and advancements. We discuss the key features of these evergreen areas and conversational trends to inspire in rapidly evolving techniques. We review the latest studies to underline the current advancement in research and the engineering and clinical aspects of sweat-based wearable biosensors for researchers, engineers and healthcare professionals working in the design and scientific study of system development and healthcare monitoring.
