A TED Talk on Prosthetic Arms

Since I’ve mentioned prosthetic limbs a few times, I thought I might as well link to this TED talk discussing the concept behind current and coming prosthetic arms. This researcher, Todd Kuiken, uses a different method than what I’ve discussed before: instead of interacting directly with the brain, his arms interact with the nerves that had previously projected to the hand, but in amputees now end in the chest.

He also touches on the possibility of arms that can transmit sensory information. While my related post today was on a technology for a better sensor that could be used in prosthetic arms, it looks like the technological barrier in the arms Kuiken discusses is how to transmit sensory information to the patient’s sensory nerves with good resolution, which is a separate issue.
