Low-voltage artificial neuron enables direct communication with living tissue
Researchers built a low-voltage artificial neuron that operates at biological neuron voltages (~60–130 millivolts) using a memristor tuned with Geobacter nanowires, producing neuron-like spikes and enabling real-time communication with living cells (initially cardiomyocytes), with energy efficiency and fewer amplification needs—paving the way for closer brain–machine integration, though not yet a medical device.
