摘要
针对可穿戴传感器,即柔性压力传感器的性能参数和在下肢膝盖穿戴的数据进行采集、整理和分析研究。结果表明,膝部进行弯曲运动时柔性传感器有明显的压电效果,对应输出的AO模拟量与压力大小呈线性相关,故可有效实时地检测人体膝关节的活动情况。此外,膝关节相对于人体其它部位而言,使用频率大,无论是走路还是休息,始终处于不同的状态,因而具有实际的研究意义。
Wearable sensor based motion recognition of the body has a promising future.This article collects,collates,and analyzes the wear sensor,the performance parameters of the flexible pressure sensor,and the data worn on the knees of the lower limbs.The results show that the flexible sensor has obvious piezoelectric effect with the knee flexion movement,and the corresponding output AO is linearly related to the pressure,therefore,can effectively detect the knee joint activity in real time.In addition,the use of the knee joint is relatively large compared to other parts of the human body,and it is always in a different state whether it is walking or resting.Therefore,it has practical significance.
