Researchers build brain-like memory device for AI sensors that may improve energy efficiency — phototransistor device combines light sensing, memory, and processing to cut data movement

Oregon State University researchers have developed a brain-inspired phototransistor that combines light sensing, memory, and signal processing in one device. The hardware can electronically control how long optical memories persist or fade, potentially improving energy efficiency in future AI vision systems.
