What is it? It is an interdisciplinary research area that combines neuroscience, neurology, engineering, physics, chemistry, psychiatry, cell biology and genetics to analyze neurological function and design solutions to problems associated with neurological limitations and dysfunction(Durand, 2006).

How does it work? Sensor receives electrical signals when muscle is movedInfo received by controllerController commands electric motor to move armIssues One motion at a timeHeavy and expensive

Deka Luke Arm DEKA arm invented by Dean Karmen Inspired by Star Wars Recently approved by FDASame weight and size as natural limbCan perform complex tasks that requires simultaneous movement

DEKA Luke arm 2014 9Targeted Reinnervation Rehabilitation Institute of Chicago Amputated nerves are transferred to muscles that no longer function nerves grow (reinnervate) in muscle provides more control signals to move the prosthetic arm Skin can be reinnervated to give prosthetic arm sense of touch Whats next? Real-time time touch sensations through a bionic hand Provide information about object being touched Silvestra Micera et al. (2014) case study on restoring natural sensory feedback in real-time

Bionic Eye Developed by University of Melbourne, Bionics Vision Australia and other institutes Help people with retinitis pigmentosa and age-related macular degeneration

How does it work?

What do you see? Takes a few months to adapt to implantCamera sends pixelated image of basic outline of objectLyndon da Cruz et al. (2013) study of the Argus II bionic eye revealed participants could identify letters as small as 0.9 cm.

Current Research More electrodes and higher voltage for better vision Safe removal of retina implantSafer and more efficient surgical procedures
