One of the stumbling blocks being faced by the development of bionic prosthetics is the difficulty of developing a method of controlling an artificial limb, especially in a manner that would seem natural to the wearer. Advances in creating brain-machine interfaces have seen major advancements in recent years, but are still hampered by the difficulty of picking up the brain’s faint signals by sensors placed on the scalp.

Stronger signals can be received if the sensors are placed directly on (or in) the brain, but that method requires invasive, and potentially dangerous brain surgery. However, a new implant inserted through the subject’s blood vessels might help reduce the risk of inserting such implants.
