We have covered plenty of exciting prosthetic limbs here in the past. Physicians and biomedical engineers from Johns Hopkins have come up with a mind-controlled prosthetic arm that supports individual finger movements. The researchers used an array of 128 electrode sensors to collect brain data. The prosthetic arm moves fingers based on brain activity.
The above GIF shows this prosthetic arm in hand.
