Scientists Built a Computer Using Living Human Brain Cells—Now It Can Decode Braille

Biohybrid computers made of organoids—tiny human brain models using real cells—have reached an important new benchmark by reading braille for the first time, even under challenging conditions.

Although biohybrid computers could eventually offer advantages in energy efficiency, demonstrating that they can reliably process and transmit meaningful information remains a work in progress. The Bristol team sought to advance this research by developing organoids modeled on the human forebrain and testing their ability to process information encoded from Braille characters.
The researchers ultimately achieved an 83% classification accuracy rate by combining signals from three brain organoids to identify Braille letters.
“We can take information from a real tactile sensor, turn it into a form that a living neural network can receive, and then recover meaningful information from the organoid response,” said first author Tianyi Liu, PhD candidate at Bristol University. “That gives us a practical way to connect artificial sensors with biological neural systems, which are a very interesting possible route towards more energy-efficient computing.”
