Neurotechnology is used by planting a chip or implant into the subject, and then it is used to monitor their nervous system. Then the implant can then check everything going on in their mind, and act as a brain to computer interface, using the electric signals from the brain, turning them into wireless signals, and can be sent to other devices. For example, if you think about the door unlocking, and then the chip will turn that thought into a signal, send it to the door, and then it will unlock. However, it is relatively new, and only has a 75% accuracy, so it still has some work to do.
Today, a device called the CUE1 has been developed to help people with parkinson’s disease, even able to stimulate the body to remove the effects, such as stiffness, and the CUE1 has been used to give patients the ability to once again dance, as well as complete fine motor tasks or anything that requires very careful movement like medical procedures, which would otherwise be impossible among Parkinson's patients. Also, Northwell Health has used a microchip which was able to reestablish the connection between a man's mind and his arm, after being paralyzed years before. This was done over a 15 hour long surgery to insert chips into the patients mind and arms, with the chips acting as an “electronic Bridge”, that can stimulate the muscles that the patient wanted to move, creating a wireless spinal cord from his mind to his limbs.
