Force-controllable ankle foot orthosis (AFO) to assist drop foot gait
… of the toe during swing (toe drag). The current assistive device is the Ankle Foot Orthosis (AFO), which though offering some biomechanical benefits, is nonadaptive and fails to eliminate significant gait complications. An Active Ankle Foot Orthosis (AAFO) is presented where the impedance of the …

Architectures of soft pneumatic actuators for wearable human assistive applications
This thesis presents the design and analysis of two novel fabric-like architectures of soft pneumatic actuators known as Fiber Reinforced Elastomeric Enclosures (FREEs) and studies the implication of wearing them as sleeves around the elbow joint. The first architecture is a helical arrangement of …
