a, Non-invasive sensory feedback. The output of sensors on the bionic hand drives mechanical or electrical stimulation of the skin to convey information about contacted objects, in this case through stimulators housed in an armband. b, Sensory feedback via an electrical interface with the peripheral nervous system. Sensors on the bionic hand drive the electrical stimulation of a nerve to elicit sensations referred to the phantom hand. c, Sensory feedback via an interface with the central nervous system. Sensors on the bionic hand drive the electrical stimulation of the central nervous system to elicit sensations referred to the de-afferented hand. Credit: Image courtesy of Kenzie Green
