Reviews on Flexible Force Sensors Based on Fiber Assemblies with Mass Production Efficiency

Flexible force sensors show great potential applications in smart wearable devices based on their softness and ease of deformation. Textiles are extremely compatible with the human body, where mechanical forces generated by human movements and physiological activities create rich application scenarios for flexible force sensors. Currently, the bottleneck in the development of flexible sensors depends on the breakthrough of mass production efficiency, which has been a research focus in recent years to accelerate the application of smart textiles in various fields. This work reviews the research progress of flexible force sensors based on fiber assemblies with mass production efficiency, which is discussed in four aspects: sensing mechanisms, structure design, preparation methods, and application. Finally, the challenges faced by mass production of flexible force sensors are analyzed and summarized, and a few inspirations for their future development direction are provided. This review summarizes the research progress of flexible force sensors based on fiber assemblies considering mass production efficiency. From both microscopic and macroscopic levels, the structural design of flexible force sensors is discussed along with their large-scale preparation methods. The prospect of flexible force sensors is put forward from structure optimization, control of costs, integrated manufacturing technology, and standardized assessment. image
