Pneumatic ergonomic crutches
… address these issues, we developed the pneumatic ergonomic crutches (PEC) that consisted of a pneumatic sleeve orthosis, an energy harvesting system and an energy storage system. The pneumatic sleeve orthosis utilized a soft pneumatic actuator, called fiber-reinforced elastomeric enclosure, coiled …
