In Nature Nanotechnology, Northwestern University researchers used aerosol jet printing with graphene and molybdenum disulfide inks on a partially decomposed polymer substrate.
The devices produced neuron-like single spikes, continuous firing and bursts, with voltages and spike shapes matching biological signals closely enough to interact directly with mouse cerebellum tissue.
The work aims to help AI emulate the brain, which runs on about 20 watts and is far more energy efficient than power-hungry data centres, though artificial synapses are still needed.
How can this 20-watt brain-mimic technology escape the lab to compete commercially with today's AI?
Is a common industrial powder the secret ingredient for building the next generation of ultra-efficient AI?
As neuroprosthetics boom, will printed neurons become the key to restoring lost human functions?
When artificial neurons can trigger real brain cells, where do we draw the line between therapy and enhancement?
What are the long-term risks of merging these artificial neurons with a living human brain?
