Engineers at Northwestern University have created printed artificial neurons capable of communicating directly with living brain cells. Built from flexible, low-cost materials like graphene and molybdenum-based compounds, these devices mimic the dynamic electrical behavior of real neurons.

In tests with mouse brain tissue, the system successfully activated live neural circuits, overcoming the rigidity limits of traditional silicon electronics. The result is a major step toward seamless brain–machine interfaces, advanced neuroprosthetics, and a new class of energy-efficient AI inspired by biological computation.

This breakthrough points to a future where electronics and living systems merge—reshaping medicine, neuroscience, and next-generation computing.
