Scientists have developed a brain-controlled robotic hand that allows people with spinal cord injuries to perform simple daily operations, such as using a knife and fork or drinking water from a cup.

 

This low-cost device was tested in Spain for six people with quadriplegia leading to loss of grip and handling.

 

By wearing a cap that measures brain activity and eye movements, the subject can feed the signal back to a tablet and connect the glove-like device to their hands via computer control.

 

Through this small-scale practice test, the participants indicated that they were able to perform their daily activities better after using the robotic hand.

 

It is no news that the brain-controlled robot assists the patient. However, many existing systems require implants or use wet gels to transmit signals from the scalp to the electrodes, but these methods can lead to health and other related problems. After using the gel, it needs to be washed off the patient's hair, making it impractical in everyday life.

 

The researchers said, " Patients have indicated that their daily behavior is very difficult if they are not assisted. They think the system is reliable and practical, and that there is no discomfort during or after use . "

 

Participants can learn how to use the system in just 10 minutes and perform simple tasks such as picking up potato chips or signing a document.

 

Despite this, the system still has some limitations. For example, the user's shoulder and arm functions must have sufficient functionality and require another person to assist with the installation of the system, and the like.

 

The system may be available in the market two years later, and depending on the function, the price may range from 5,000 to 10,000 euros ( $ 5,370 to $ 10,740 ).

 

The device can also be used to help stroke patients with rehabilitation training.
