Restoration of sensory information via bionic hands

Nat Biomed Eng. 2023 Apr;7(4):443-455. doi: 10.1038/s41551-020-00630-8. Epub 2020 Nov 23.


Individuals who have lost the use of their hands because of amputation or spinal cord injury can use prosthetic hands to restore their independence. A dexterous prosthesis requires the acquisition of control signals that drive the movements of the robotic hand, and the transmission of sensory signals to convey information to the user about the consequences of these movements. In this Review, we describe non-invasive and invasive technologies for conveying artificial sensory feedback through bionic hands, and evaluate the technologies' long-term prospects.
