Development of a Robust Sensory Feedback System for Persons with Lower-Limb Sensory Deficits

This project develops a system to provide augmentative sensory feedback in the lower limbs of amputees and diabetic/vascular patients by enhancing sensory function resulting in improved mobility and improved quality of life. The sensory feedback system detects force loads at the base of the foot or prosthesis and translates this force, via pneumatic control system, to pressure points on the upper thigh using tactile balloon actuators. By providing tactile stimuli on the skin of the upper leg, the system uses an information feedback pathway that was previously unused. Phase I build’s upon the foundation of the prior research efforts to design a sensory feedback system that is practical for activities of daily living and expanded clinical testing.
