Artificial Ankle-Foot System with Parallel-Spring and Series-Elastic Actuator Components
Exclusively Licensed
Invention type: Technology
/
Case number: #12752TE
A powered ankle-foot prosthesis, capable of providing human-like power at terminal stance that increase amputees metabolic walking economy compared to a conventional passive-elastic prosthesis. The powered prosthesis comprises a unidirectional spring, configured in parallel with a force-controllable actuator with series elasticity. The prosthesis is controlled to deliver the high mechanical power and net positive work observed in normal human walking.
