A Water Compartment Cell Culture Lid Enables Stable Longitudinal Recording of Neuronal Networks In Vitro

open access: yesAdvanced Science, EarlyView.
A cell culture lid with an integrated water compartment eliminates evaporation from microelectrode arrays while preserving gas exchange. Freed from the osmotic drift and repeated medium exchanges that disturb conventional recordings, patterned human iPSC‐derived neuronal networks are recorded continuously for five weeks. Single‐spike resolution reveals

Device Stochasticity Directly Implements Bayesian Sampling in Spiking Neurons

open access: yesAdvanced Science, EarlyView.
Brain‐inspired stochastic spiking turns device noise into Bayesian uncertainty for robust, low‐power neuromorphic computing. ABSTRACT Device stochasticity is considered a non‐ideality in neuromorphic hardware, although stochastic neural activity supports probabilistic computation in biological systems.

Membrane‐Targeted Nanoparticles for Neuronal Photomodulation

open access: yesAdvanced Science, EarlyView.
Immobilizing gold nanoparticles on the neural interface using a bioorthogonal approach generates localized heat upon exposure to near‐infrared light, temporarily inhibiting primary neuronal activity without damaging the cells. This precise placement and retention of nanoparticles at the cell membrane expand the strategies for non‐invasive neural ...

Rethinking Cochlear Implants: The Need for Precise Temporal Coding

open access: yesAdvanced Science, EarlyView.
Spatial hearing relies on sensitivity to interaural temporal cues, but this sensitivity is often poorly developed in patients with cochlear implants, particularly those with early‐onset hearing loss. Rats with cochlear implants, however, demonstrate excellent temporal sensitivity, suggesting that this limitation is not inevitable.

Boron Crosslinking Enables Anion‐Lean Solvation and Stable Interfaces for Dendrite‐Free Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
The boron‐crosslinked gel polymer electrolyte (GPE_TMAB) enhances Li+ transport through Lewis‐acidic boron centers that selectively immobilize TFSI− anions, thereby enabling single‐ion conduction and promoting dendrite‐free lithium deposition. The engineered solvation structure drives the formation of an inorganic‐rich, mechanically robust SEI ...

Localized Hydrogen Release Driven by Mg–Pd Microgalvanic Cells from 3D‐Printed Microneedles Reverses Redox Homeostasis for Psoriasis Treatment

open access: yesAdvanced Science, EarlyView.
A 3D printing microneedle (MP‐MN), loading magnesium‐based micro‐galvanic cells (MP), is designed for improving psoriasis. H2 generated from MP‐MN scavenges ROS and •OH, actives NRF2‐KEAP1 pathway, and decreases inflammation, thereby effectively restoring the oxidative stress homeostasis of psoriatic skin and suppressing the excessive proliferation of ...

Synchronization of Analog Neuron Circuits With Digital Memristive Synapses: An Hybrid Approach

open access: yesAdvanced Electronic Materials, EarlyView.
An hybrid circuit mimicking neural units coupled using memristive synapses is introduced. The analog neurons provide flexibility and robustness, and the digital memristive coupling guarantees the full reconfigurability of the interconnection. The onset of a synchronized spiking behavior in two circuits mimicking the Izhikevich neuron is discussed from ...

Experimental Demonstration of Temporally Aware Fault‐Tolerant Sensor Fusion Using Memristive Associative Learning

open access: yesAdvanced Electronic Materials, EarlyView.
In dynamic driving scenarios, the proposed approach ensures only temporally aligned sensor inputs to make driving decisions, preventing false activations. By enabling selective hardware‐level learning, it achieves fast, reliable responses under noisy conditions.

Eco‐Friendly Laser‐Induced Graphene/Perovskite Hybrids for Eco‐Friendly Photodetectors

open access: yesAdvanced Electronic Materials, EarlyView.
A sustainable paper‐based photodetector was developed by combining laser‐induced graphene (LIG) with MAPbI3 perovskite. Compared with pure LIG devices, the hybrid photodetector exhibited nearly 10‐fold higher responsivity and 7‐fold greater detectivity while maintaining stable performance after 1000 bending cycles, demonstrating its potential for ...

Determining the Relationship Between Composition, Structure, and Device Properties of GexSe1‐x‐Based Selector‐Only Memory

open access: yesAdvanced Electronic Materials, EarlyView.
Composition‐dependent structural evolution in GeXSe1‐X selector‐only memory (SOM) is correlated with device switching behavior. Increasing Ge strengthens network rigidity, suppresses atomic motion, and stabilizes threshold switching, while narrowing the memory window. The revealed structure–property relationship provides a guideline for compositionally
