Abstract

Chronic ankle instability (CAI) refers to the phenomenon of frequent ankle sprain caused by damage to ligaments around the ankle, which has a very high incidence in the sports population with great negative effect on people’s daily life. The physical diagnosis of CAI is mainly based on the degree of ankle ligament relaxation (ALR), but the widely used anterior drawer test (ADT) mainly relies on the experience of doctors and unquantifiable, leading to high incidence of misdiagnosis. In this work, a biomimetic porous graphene-SBR (styrene-butadiene rubber) strain sensor (PGSSS) with a high gauge factor (210), a wide measuring range (90%), and high durability (10,000 stretching cycles) is designed and integrated into a wearable system to monitor, process, transmit, and display ankle skin strain data for ALR analysis in real-time. The PGSSS-based wearable system can accurately monitor ALR, which is of great significance for accurate diagnosis and efficient rehabilitation of patients suffering from CAI.

基于多孔石墨烯应变传感器的可穿戴踝关节韧带松弛监测系统

慢性踝关节不稳(Chronic ankle instability, CAI)是指踝关节周围韧带损伤引起的频繁踝关节扭伤的现象，在运动人群中发病率很高，对人们的日常生活有很大的负面影响。CAI的物理诊断主要基于踝关节韧带松弛程度(ALR)，但广泛使用的前抽屉试验(ADT)主要依靠医生的经验，无法量化，导致误诊的发生率高。在这项工作中，仿生多孔石墨烯- sbr(苯乙烯-丁二烯橡胶)应变传感器(PGSSS)具有高测量因子(210)，宽测量范围(90%)和高耐用性(10,000次拉伸循环)被设计并集成到可穿戴系统中，以实时监测，处理，传输和显示脚踝皮肤应变数据，用于ALR分析。基于pgsss的可穿戴系统能够准确监测ALR，对CAI患者的准确诊断和高效康复具有重要意义。
