A pioneering collaborative research initiative encompassing the expertise of the Daegu Gyeongbuk Institute of Science and Technology (DGIST), KAIST, Ajou University, and Soongsil University has led to the remarkable creation of next-generation multifunctional fibers.
These innovative fibers are distinguished by their exceptional three-dimensional structure, marking a significant advancement in material science that promises to enhance various applications across multiple fields.
The innovative findings of this study have been featured as a cover article in Advanced Fiber Materials, a leading international journal in the field of new materials.
Professor Bonghoon Kim from the Department of Robotics and Mechatronics Engineering at DGIST is at the helm of this pioneering work.
He and esteemed colleagues Professor Sangwook Kim from KAIST, Professor Janghwan Kim from Ajou University, and Professor Jiwoong Kim from Soongsil University have successfully created a sophisticated multifunctional sensor using semiconductor fibers that mimics the human senses.
This cutting-edge technology holds tremendous potential for diverse applications, particularly in wearables, the Internet of Things (IoT), advanced electronic devices, and soft robotics.
The newly developed semiconductor fiber sensor significantly outperforms traditional one-dimensional fiber sensors.
Its unique design enables the sensor to respond sensitively to fluctuations in the surrounding environment.
This advanced fiber technology can simultaneously detect and monitor various stimuli, including light, chemicals, pressure, and environmental metrics such as pH levels, ammonia (NH3), and mechanical strain.
By integrating these functions, the research team has crafted a sensor platform that can process multiple signals concurrently, emulating how humans perceive their environment through their senses.
Three-dimensional shapes
A key aspect of this study lies in fabricating fibers that can be freely adjusted into three-dimensional shapes, achieved through an innovative process utilizing molybdenum disulfide (MoS2).
Notably, the fibers’ naturally occurring spiral structure, formed during their transition into a ribbon-like configuration, allows for precise manipulation of their curvature.
The outstanding electro-mechanical properties of MoS2—coupled with the aligned structure of the fibers—contribute to their superior performance and ability to sense a wide array of environmental information.
Professor Kim emphasized the significance of this research, stating, “This study has greatly expanded the range of applications for two-dimensional nanomaterials such as molybdenum disulfide. We are committed to exploring various materials and advancing technologies that can effectively measure the signals necessary for wearable technologies.”
MoS2, a two-dimensional nanomaterial made of molybdenum and sulfur, has garnered attention for its remarkable electrical, optical, and mechanical properties.
Its wide range of applications—from semiconductors to lubricants and energy storage—highlights its versatility in modern technology.
