Wireless, Laser-Shooting Brain Implant the Size of a Grain of Salt
Our brains, for all their brilliance, can fail in a surprising number of ways — from memory loss and migraines to depression and dementia. This inventive decay often turns human existence into an inner struggle.
“Good news, everybody!”
That well-known Futurama catchphrase fits perfectly here: scientists from Cornell University, together with their international collaborators, have made a groundbreaking leap in neural technology. They created an implant so minuscule it could rest on the tip of a pin.
This new device, once placed in a mouse’s brain, can wirelessly transmit data about neural activity for over a year without external power. The innovation combines compact engineering and smart energy use in one extraordinary package.
The project’s results, published in Nature Electronics, were led by Sunwoo Lee, assistant professor at Nanyang Technological University, alongside Cornell researchers. Their invention bears a fittingly futuristic acronym — MOTE, short for Microscale Optoelectronic Tetherless Electrode — a tool that seems born from science fiction yet firmly belongs to real-world science.
