Year: 2025

Type: article

Abstract: In recent years, fibrillar string-based wearable sensors have gained significant attention for their ability to detect mechanical and physiological stimuli, including tactility, temperature, humidity, and glucose levels. Stretchability, flexibility, and lightweight nature of the fibrillar strings make them ideal for integration into textiles and wearable devices. This review highlights recent advancements in the fabrication of fibrillar string sensors by using various spinning techniques, including dry spinning, wet spinning, melt spinning, and light polymerization spinning. The examination of conductive material integration into fibrillar strings highlights progress in this field, including advancements in composite fabrication and structural engineering. Furthermore, the review discusses the potential applications of these sensors in health monitoring, including mechanical stimuli, temperature, humidity, glucose levels. The article highlights ongoing challenges in fibrillar string sensors such as enhancing durability and sensitivity under mechanical strain, and suggests future research directions to improve the performance and functionality in wearable sensors.
