Electrical‐Programming‐Free Neural Crossbars Enabled by Photochemical Weight Patterning

ABSTRACT Hardware neural networks based on crossbar architectures require reliable implementation of multilevel synaptic weights, yet conventional electrical programming often suffers from programming interference, device variability, and write–verify overhead. Here, we present e...

Emerging Post‐CMOS Hardware Neurons for Brain‐Inspired Computing: Devices, Circuits, and System Integration

ABSTRACT The fundamental energy and latency limitations of the von Neumann architecture have necessitated a paradigm shift toward neuromorphic systems. This approach addresses the “memory wall” bottleneck by emulating the brain's event‐driven and massively parallel processing cap...

Stretchable electroluminescent devices based on microLEDs: materials, fabrication, system design, and applications

Micro-light-emitting diodes (microLEDs) have emerged as one of the most promising emitters for stretchable electroluminescent (EL) devices owing to their high brightness, efficiency, operational stability, and environmental robustness. This review summarizes recent advances in mi...
