Description
Tingting Mei and a large team of co-authors build an artificial synapse that runs on light alone. Their paper is from two thousand twenty-six. A synapse is the link between nerve cells, and its strength can rise or fall with use. Machine versions of synapses are key parts of brain-like computing for vision.
Their device uses a lead-free layered material joined to a carbon film. Visible light strengthens the link, while near-infrared light weakens it. That two-way control sets it apart from past devices that used one mode only. Each event uses about one femtojoule of energy, an extremely small amount. The device kept its states for long spans of time. In tests it handled traffic sign reading and target tracking tasks well.
