Scientists Develop Rice-Sized Wireless Brain Implant That Transmits Signals Through Light
Innovation: Scientists have created a brain implant chip smaller than a grain of rice. This chip, implanted inside the brain, captures electrical signals and transmits them through infrared light.
Scientists have been successful in creating a brain implant chip less than the size of a grain of rice. It is implanted inside the brain and transmits electrical signals through infrared light. The discovery is perceived as a major breakthrough in the world of neurotechnology. This small device is called MOTE. It's a Micro Scale Opto Electronics Tetherless Electrode-the tiniest wireless brain implant ever designed. Cornell University engineer Alyosha Molnar, who developed it, said, "This is the smallest device ever made that can measure brain activity and transmit it wirelessly."
A brain implant chip is a tiny computer chip that is surgically implanted into the human brain. Its purpose is to connect the brain directly to computers and other electronic devices, allowing even severely paralyzed or disabled people to control them using their minds alone. This chip reads neural signals from the brain and converts them into digital commands, making it possible to move a cursor, play games, or type.
This chip is approximately 300 microns long and 70 microns wide—about as thin as a human hair. It converts brain signals into light, which then travels through brain tissue to a receiver. This idea has been in the works since 2001, and it took scientists nearly 20 years to realize it.
