Engineers at Northwestern University created artificial neurons that can interact with real brain cells. These devices produce electrical signals similar to those generated by living neurons.

In a breakthrough, engineers at Northwestern University have developed printed artificial neurons that can directly communicate with living brain cells. These flexible and low-cost devices mimic the behavior of real neurons, allowing them to activate biological brain tissue.

In experiments using slices of mouse brain, the artificial neurons successfully triggered responses in real neurons. This achievement shows a new level of compatibility between electronic devices and living neural systems.

This advance brings researchers closer to creating electronics that can directly interface with the nervous system. Potential uses include brain-machine interfaces and neuroprosthetics, such as implants that could help restore hearing, vision, or movement.

The technology also points towards a new generation of computing systems inspired by the brain. By replicating how neurons communicate, future hardware could perform complex tasks using far less energy.

The study will be published on April 15 in the journal Nature Nanotechnology.

According to Mark C. Hersam, who led the study, 'The way you make AI smarter is by training it on more and more data. This data-intensive training leads to a massive power-consumption problem.' He hopes that by applying brain-inspired principles to modern technology, they can create more energy-efficient hardware.

Hersam is an expert in brain-inspired computing and holds multiple roles at Northwestern University, including the Walter P. Murphy Professor of Materials Science and Engineering at the McCormick School of Engineering.
