Biomimetic Prosthetic Knee Using Antagonistic Muscle-Like Activation

Abstract

The majority of commercial prosthetic knees are passive in nature and therefore cannot replicate the positive mechanical work exhibited by the natural human knee in early and late stance. In contrast to traditional purely dissipative prosthetic knees, we propose a biomimetic active agonist-antagonist structure designed to reproduce both positive and negative work phases of the natural joint while using series elasticity to minimize net energy consumption. We present the design and implementation of the active knee prosthesis prototype.

“…Kapti and Yucenur [18] also worked on design and control of an active artificial knee joint. A biomimetic variable impedance knee prosthesis was proposed by Martinez and Herr [19] in order to improve gait and metabolic energy consumption of above-knee amputees on variant terrain conditions. Joshi and Anand [20] discussed about actuators like electrorheological and magnetorheological fluids.…”
