Bias-reconfigurable barrier photodetectors for integrated broadband sensing and neuromorphic vision

Intelligent vision systems demand photodetectors with reconfigurable response to support diverse modalities like high-speed sensing and neuromorphic processing. Here we show a bias-reconfigurable barrier photodetector that enables continuous modulation of response time across 7 o...

Mask‐Free Electro‐Addressable Localization of GOx@ZIF‐8 on Prussian Blue Microelectrodes for Glucose Biosensing

Precisely integrating MOF powders into patterned electrochemical devices remains a processing challenge, as conventional methods often require masks, manual alignment, or poorly scalable steps and can lead to non-selective deposition and inefficient material use. While electropho...

Emulation of Synaptic Functions with Poly(Ionic Liquid) Heterojunction for Visual Pattern Recognition

Abstract The progress in artificial intelligence has driven the development of bioinspired iontronics for neuromorphic computing, offering scalability and energy efficiency. Ionic-liquid-based iontronic devices have emerged as capable of emulating the complex functions of neurons...

Extreme‐Fast‐Charging Li‐Ion Batteries via Activation‐Energy Regulation With a Li 3 PO 4 ‐Li 2 SO 4 ‐Rich Solid Electrolyte Interphase

ABSTRACT Extreme‐fast‐charging (XFC) batteries are essential for widespread electric vehicle adoption. Although heating‐assisted charging enables ultrafast charging at elevated temperatures (e.g., 65°C), it increases the risk of thermal runaway. Lowering the activation energy of...

Omnidirectional bending sensor with three-fold structural symmetry enables decoupling of bending angle and direction

Accurate shape sensing requires simultaneous quantification of bending angle (φ) and bending direction (θ). Yet existing bending sensors remain confined to uniaxial or discretized modes, relying on tedious, non-generalizable calibration procedures. Here, we present a snowflake-sh...

A spiking neural network-in-logic architecture based on reconfigurable molybdenum disulfide dual-gate transistors with ferroelectric gating

Efficient processing of high-dimensional perceptual data is a challenge in modern electronics, as neuromorphic systems typically process all input features indiscriminately, leading to excessive neuronal activation and high energy consumption. A key issue is the lack of a hardwar...

“Swab-and-Stain” Nanoparticle Assay for Detection of PBP2a-Expressing Methicillin-Resistant Staphylococcus aureus Toward Point-of-Need Environmental Surveillance

Surveillance of methicillin-resistant Staphylococcus aureus (MRSA) in the environment is crucial for reducing its transmission, particularly in hospitals, nursing homes, and high-contact public areas. Rapid Point-of-Need (PON) tools at healthcare facilities, without involving pro...

Atomically thin amorphous carbon with an ultralow dielectric constant

Two-dimensional (2D) materials could replace conventional electronic components. Key advances have already been made in applying 2D materials to integrated circuits, but a robust, atomically thin ultralow-k dielectric remains crucial for further circuit scaling. Minimizing parasi...

High‐Performance Self‐Assembled Amphiphilic Block Copolymer Thermoelectric Ionogel for Low‐Humidity Heat Harvesting

ABSTRACT Ionic thermoelectric (i‐TE) materials have attracted considerable interest due to their abilities to generate high thermovoltage for low‐grade waste heat harvesting. However, challenge still remains to develop high‐performance i‐TE materials, especially at relative low h...

An ElectronicallyCoupled Interfacial Energy Descriptorfor Predicting Coulombic Efficiency in Aqueous Zinc Batteries

Abstract Solid–liquid interfaces dictate the performance and longevity of aqueous batteries. While rationally designed electrolyte additives offer a potent strategy to stabilize these interfaces, the complex interactions between additives and metal surfaces are difficult to isola...
