Sensory Feedback Schemes

Discrete Event Sensory Feedback During Teleoperation of a Prosthetic Hand

Biomechatronics Development Laboratory | University of Colorado

Chief Scientist

Artificial sensory feedback schemes can provide users of prosthetic hands with the sense of touch.  Here I implemented a novel sensory feedback scheme using vibrotactile stimulation during teleoperation of a prosthetic hand with our collaborators from the BioRobotics Institute at Scuola Superiore Sant'Anna in Pisa, Italy.
