    Abstract With the continuous development of flexible electronics, multi-functional device integration, artificial intelligence technology, etc., flexible wearable sensors are playing an increasingly important role in people's daily motion monitoring. However, current flexible wearable sensors have problems such as low accuracy, poor real-time performance, and poor stability in motion monitoring, which seriously hinder the better application of flexible wearable sensors and are not conducive to the collection and monitoring of motion signals. To this end, this paper designed a flexible wearable sensor motion monitoring system and tested its performance through the preparation and performance research of new functional polymer conjugated materials. The research results show that the motion monitoring system designed based on the new functional polymer conjugated material flexible wearable sensor has good monitoring accuracy and real-time performance. When the output data is 500 pieces, the running monitoring accuracy reaches 95.4%, and the monitoring feedback time is 0.321 s; the high jump movement monitoring accuracy rate reaches 97%, and the monitoring feedback time is 0.287 s; the long jump movement monitoring accuracy rate reaches 96%, and the monitoring feedback time is 0.296 s. This shows that the flexible wearable sensor motion monitoring system of this paper has better performance and can meet the current demand for accuracy and real-time motion monitoring. This study highlights the impact of new functional polymer conjugated materials on flexible wearable sensors, helping to further solve the deficiencies of flexible wearable sensors in sports monitoring and promote their better development.

    Abstract Puncture-resistant clothing plays an important role in martial arts. This article studies the preparation process of multi-layer flexible stab-resistant fabrics, analyzes the sports properties of the fabric, and explores the potential application of stab-resistant clothing in martial arts. This article uses ultra-high molecular weight polyethylene fiber as raw material, preprocesses it, including fiber cleaning, drying, lamination, and laminating them together through needle punching, then soaks the laminated fibers in resin, and the soaked fibers solidifies to form a specific flexible puncture-resistant fabric. This article prepares three types of layered fabrics, namely woven fabrics, nonwoven materials, and composite materials of nonwoven materials + woven fabrics + nonwoven materials, and analyzes the kinematic characteristics of the three layered fabrics. Experimental results show that when the number of layers is 4, the average breaking tensile forces of woven fabrics, nonwoven materials and composite materials are 3400, 4600 and 3860 respectively, and the average breaking elongations are 11.8%, 40.6% and 17.4% respectively. This shows that woven fabrics have the highest levels of air permeability and moisture permeability.
