US: Princeton scientists make 3D bio-electronic hybrid system using brain cells

Princeton scientists built a 3D bio-electronic mesh of microscopic wires and electrodes that supports living neurons.

The hybrid system stayed stable for more than six months and was trained to distinguish spatial and temporal electrical patterns.

Published in Nature Electronics, the work points to new ways to study neural circuits and wetware computing.

It may also inspire more energy-efficient alternatives to conventional AI hardware.
