Scientists Invent System to Control Artificial Hands through Brain Signals

A new system that can read brain signals is developed by scientists from the University of Essex. This system has extensive potential to help users control artificial hands just by their thoughts. The invention acts as a crucial milestone for stroke patients to regain the ability of finger movements.

Partial paralysis caused by stroke or spinal injuries often leaves people socially disconnected. The invention of such a system is expected to fulfill the dream of returning back to their normal life again.

IIT Researchers Develope Brain-Computer Interface (BCI) to Treat Brain Injuries

Dr. Haider Raza, from the University of Essex, is working on developing the brain signal reading system in such a way that it could fulfill the basic needs of patients. IIT Kanpur researchers are also carrying out experiments on inventing a brain-computer interface (BCI) to read a person’s brain waves. They are aiming at converting those brain waves into computer signals. This study could make researchers gain more knowledge about brain injuries. Consequently, it could unravel an in-depth understanding about the treatment of associated injuries.

The invention of BCI technology not only promises to detect brain injuries but also can control a computer by just using the mind. For instance, paralyzed patients need to ‘imagine’ making movements in order to restore movement in paralyzed body parts. However, just imagining is not sufficient to trigger brain signals. Along with it, active practice is also essential which made the researchers design an exoskeleton for hands.

The artificial hand will be connected with the system which can read brain signals. This invention gives the patient both physical and mental practice, thus aimed towards curing paralysis in the near future.
