Application of Hydrogel-Based Flexible Pressure Sensing Film in Smart Taekwondo Protective Gear

Abstract

The rapid development of smart sports equipment has placed higher demands on motion monitoring technology. Hydrogel-based flexible pressure sensing films, with their excellent flexibility, biocompatibility, and tunable electrical properties, provide an innovative solution for the development of smart Taekwondo protective gear. This study systematically analyzes the sensing mechanisms and mechanical properties of hydrogel materials, optimizes the film preparation process and conductive network construction strategies, and proposes a distributed sensing network design for high-dynamic impact monitoring. Through simulated impact tests and bio-mechanical validation, it is confirmed that the system can achieve accurate quantification of striking force and analysis of motion data, providing a new technical pathway for the application of flexible sensing technology in the field of competitive sports.
