Study on Flexible Wearable Sensors for Motion Detection and Health Monitoring

Abstract

Traditional rigid sensors are increasingly inadequate for effective human motion detection and health monitoring as awareness of personal health continues to rise. Flexible wearable sensors, celebrated for their exceptional biocompatibility and sensing performance, have become a focus of research in these domains. This paper examines four types of flexible wearable sensors: resistive, capacitive, piezoelectric, and triboelectric. In Chapter 2, the paper outlines their fundamental principles of operation. Chapters 3 and 4 discuss recent innovations by various research teams on active and passive sensors, encompassing advancements in material development, structural design, fabrication methods, and application contexts. Finally, Chapter 5 provides a summary of the challenges facing the evolution of flexible wearable sensors and offers insights into future research directions.
