A group of researchers from Brown University, University of California, San Diego (UCSD), and Qualcomm recently developed a brain-computer interface (BCIs) system called ‘Neurograins’ that can sense electrical activity in the brain and transmit the data wirelessly. It records and stimulates brain activity using a coordinated network of independent and wireless microscale neural sensors. This tiny chip is almost the size of a grain of salt. 

BCIs are assistive gadgets that enable patients with brain or spinal injuries to move and communicate. These systems capture electrical impulses in the brain and use those signals to control external devices such as computers or robotic prosthetics.

In recent years, several researchers have been experimenting with BCIs to help people with speech impediments use touchscreens, keyboards, or speech-generated devices to communicate. However, they are not much of a help…
