项目摘要
Project Summary/Abstract
Power absorption and generation at the ankle is critical to gait efficiency, joint health, and
safety. For amputees, it's also an important factor in residual limb health. Recently, research
and commercial efforts have resulted in powered foot-ankle systems, which provide powered-
plantarflexion electromechanically, reduce metabolic costs of walking, and show reductions in
pathological loading of the contralateral limb. However, these devices are complex, expensive,
heavy, and physically large – all factors which limit widespread adoption.
The objective of the energy-havesting mesofluidic impulse prosthesis (e-MIP) is to create an
inexpensive, lightweight foot-ankle system which doesn't require a net energy input for
powered plantarflexion and swing-phase dorsiflexion. The energy density and bandwidth of
high pressure, meso-scale hydraulics enables an ankle that can seamlessly harvest the energy
normally dissipated in gait; store it in fluid-accumulators; and reapply it in controlled, well timed
power impulses. The benefits of powered systems are therefore realized in an anthropometric
size and weight, with a system complexity that is clinically viable.
项目总结/摘要
脚踝处的能量吸收和产生对于步态效率、关节健康和运动是至关重要的。
安全为代价的对于截肢者来说,这也是残肢健康的重要因素。最近,研究
以及商业上的努力已经产生了动力足-踝系统,其提供动力,
跖屈机电,减少步行的代谢成本,并显示减少
对侧肢体的病理负荷。然而,这些装置复杂、昂贵,
笨重、体积大--所有这些因素都限制了广泛采用。
能量收集介流脉冲假体(e-MIP)的目的是创建一个
不需要净能量输入,
动力跖屈和摆动相背屈。的能量密度和带宽
高压中尺度水力学使脚踝能够无缝地收集能量
通常在步态中消散;将其储存在液体中;并在控制下及时重新应用
动力冲动因此,动力系统的益处在人体测量中得以实现。
尺寸和重量,具有临床上可行的系统复杂性。
