Abstract
Single-Pixel Event Photoactive Device
In article number 2406607, Mohit Kumar, Hayoung Park, and Hyungtak Seo introduce a single-pixel event photoactive device with selective carrier integration that merges spatiotemporal event sensing and built-in short-term memory. It processes multibit parallel data and recognizes patterns ultrafast (0.4 μs) with ultralow energy use (25 femtojoules). Adjusting its speed allows trajectory and position detection of events through optical flow sensing.
