“…A functional neural circuit in the brain is formed by highly specific connections among billions of neurons through trillions of synapses. [ 20–22 ] Inspired by this, researchers have devoted their considerable effort in developing high‐performance artificial smart chips with computing power as powerful as the neurons. Electronic synaptic devices with synaptic functions and photosensitive have been concerned due to their ultra‐fast signal transmission and negligible interconnection crosstalk, [ 23–25 ] and their low power consumption is also urgently needed by ZIBs.…”

Aqueous Zn ion batteries are promising systems due to their intrinsic safety, low cost, and non‐toxicity, and the Zn corrosion and dendrite growth will cause the poor reversibility of Zn anode. Herein, the porous Zn@C solid, hollow, and yolk–shell microsphere films are developed as Zn anode antifluctuator (ZAAF). The prepared yolk–shell microspheres (Zn@C yolk–shell microsphere [ZCYSM]) film with superior buffering can effectively restrict the deposition of Zn metal in its interior and inhibit the volume expansion during plating/stripping process, thus modulating the Zn2+ flux and enabling stable Zn cycling. As a proof of concept, the ZCYSM@Zn symmetric cells achieve the excellent cyclic stability over 4000 h and cumulative plated capacity of 4 Ah cm−2 at a high current density of 10 mA cm−2. Concomitantly, the suppressed corrosion reactions and dendrite‐free ZAAF significantly improve the durability of full cells (coupled to CaV6O16·3H2O). Additionally, durable pouch cell and electrochemical neuromorphic inorganic device (ENIDe) are integrated to simulate neural network, providing a strategy for extreme interconnectivity comparable to the human brain.

“…Accordingly, the biological nervous system can be considered as an in‐memory computing system (i.e., the memory and logic computingfunctions into a single entity), which can significantly improve the processing speed of data‐intensive computation and reduce energy consumption. [ 1,3–5 ] Emerging novel neuromorphic device is the basic unit for high‐performance logic computing, and its most important feature is the nonvolatile memory effect, which allows the neuromorphic device to store the data in‐situ and perform logical operations simultaneously. The process of nonvolatile logic gate computing is similar to that of updating the dynamic weights in biological synapses, which enables high‐performance memory computing beyond CMOS without static power consumption.…”

General‐purpose computers usually use logic gate computing units based on complementary metal oxide semiconductors (CMOS). Due to the separate memory and computing units in Von Neumann architecture, data transmission requires great energy and time consumption. Developing novel neuromorphic devices and comprehensively investigating their logical computing mode are crucial to achieve high‐performance and low‐power neuromorphic computation. Here, a systematic summary of Boolean logic computing based on emerging neuromorphic transistors is presented. This summary encompasses logical operation modes, materials, device structures, and working mechanisms. The input mode of Boolean logic operation is classified into electrical input, optical input, and synergistic optical/electrical input. Besides, additional modulation strategies to construct programmable logic functions by electrical, optical, and thermal signals are also summarized. These strategies hold great significance as they enable dynamic reconfiguration of logic operations and provide neuromorphic devices with decision‐making capabilities. Finally, the application prospects and current challenges to Boolean logic computing based on dendritic integration are discussed from the aspects of device integration, synergistic input/modulation modes, auxiliary peripheral circuit, software/hardware system, etc. It is believed that comprehensive investigations on neuromorphic Boolean logic operations are crucial to push forward the development of future neuromorphic computing toward high efficiency and high integration density.

Bidirectional modulation of synaptic weight lays the basis for learning and memory in the brain, and the development of brain‐inspired photonic synaptic devices is hindered by deficient light‐stimulated inhibition. In this report, a type of organic thin film neuromorphic devices with a planar two‐terminal architecture, featuring as the inhibitory regulation of synaptic weight over two orders of magnitude upon selective UV illumination is developed. The in situ monitoring on the floating electrode potential and the corresponding simulation results demonstrate the effect of cumulative hole trapping in the polymer electret layer, which modulates the device conductance in a nonvolatile manner. Remarkably, UV‐induced long‐term depression is accompanied by enhanced short‐term potentiation in the device that may preserve a stable level of total synaptic activities. The UV‐stimulated inhibition and the adaptive short‐term plasticity, as well as the ON and OFF responses to light in the organic photonic synaptic device, suggest its potential applications in photonic neuromorphic computing.
