Unlike traditional fiber sensors, the newly developed semiconductor fiber sensor is highly advanced, offering the ability to detect and measure multiple environmental factors simultaneously. The fiber's unique internal structure enables it to monitor light, chemical substances, pressure, and environmental variables such as pH levels, ammonia (NH3), and mechanical strain with remarkable precision. This multifunctional capability makes it a versatile sensor platform that mimics the complexity of the human sensory system.
The research team employed a special fabrication process utilizing molybdenum disulfide (MoS2) to create fibers capable of three-dimensional manipulation. The spiral structure, naturally formed as the fibers aligned into ribbon shapes, enables precise control over their curvature. This design, combined with the exceptional electro-mechanical properties of MoS2, enhances the fibers' performance and their ability to detect various environmental stimuli.
"This study has significantly broadened the application potential of two-dimensional nanomaterials like molybdenum disulfide," explained Professor Kim. "We aim to continue exploring diverse materials and refining technologies to precisely measure signals vital for wearable technology advancements."
