Key points from article :
The micro coils make mind-controlled prosthetics easier to use.
Most brain implants are electrode-based needing a direct contact between the metal and the brain and often become less effective over time.
Micro coils are thin metal wires with single sharp bends in them which use magnetic energy instead.
Should last longer and their directional field will allow for more fine-tuned muscle movements.
Brain implants have the potential to help people with everything from Parkinson’s disease to blindness.
The study was published in the Science Advances.
