One of the next challenges in the field of brain-machine interfaces (BMIs) is making prosthetics feel like normal limbs by generating feedback pulses to the brain or nerve endings.

These will result in their bearers having an almost natural feel to their bionic limb.

A future type of BMI for patients with paralyzed limbs or spinal cord injuries will send efferent motor impulses directly to the muscles of the limb.

BMIs may alsoallow blind people to see using an artificial picture-capturing device, much like a camera.
