智能下肢假肢关键技术研究进展

Research advance on key technology of intelligent lower limb prosthesis

智能假肢是将智能检测与控制技术应用于假肢的产物,可显著提高假肢装置的安全性、功能性和舒适性,使得假肢能够达到与健肢相同的运动效果.根据人体运动具有规律性的特点,利用先进的传感器融合与智能控制技术,对速度、路况、步态等运动状态进行有效的识别,是实现假肢协调控制的基础.本文在介绍国内外发展现状的基础上,对智能假肢的控制从理论分析、样机研制、实验测试等方面进行了系统的介绍.

Intelligent prosthesis is an advanced rehabiliation device based on intelligent measure and control.It can improve the safty and function of prosthesis,as well as the comfotability.And a well-designed prosthesis might walk naturally as a health leg.The motion judgement including the speed,condition,stride,are the fundamentals of prosthesis control.Furthurmore,a survey is made in the field of intelligent lower limb prosthesis.And the theoretical analysis,proto-type design and system test of prosthesis are introduced.
