Dynamic Adaptive Visuomorphic Electronics

Photo-adaptive neuromorphic devices are crucial for artificial vision systems to process complex light conditions. However, challenges remain in achieving precise, fast responses across varying light environments. Expanding optical ranges and using multiple modes enhance adaptability, yet bidirectional modulation across the visible and near-infrared spectrum is difficult. We addressed this by developing organic photosensitive field-effect transistors with complementary p-n heterojunctions, nanopore patterning, and ternary organic heterostructures, enabling metaplasticity, adaptive light relaxation, and bidirectional photoresponses, foundational for efficient vision systems in complex lighting.
