photoresponsivity and 1000 programmable states, with excellent air stability (30 days) and thermal reliability (80°C). The scalability of these devices is demonstrated via a proof of concept 32 × 32 array. The excellent uniformity and programmability of the array are utilized in energy-efficient face detection applications (achieving 95.2% sensitivity and 4.51 × speedup for subsequent computation) in addition to image feature extraction and MNIST digit recognition tasks (96.97% accuracy). Compared to previous ISC implementations, our system offers enhanced tunability, fabrication scalability, and functional stability. These results establish a practical perovskite-based ISC platform, offering new avenues for intelligent computing systems in robotics, wearable electronics, and neuromorphic vision.
