Wearable Electro‐Thermal Haptic Stimulator Driven by a Self‐Powered Tactile Sensor for Realistic Stimulus Replication

open access: yesAdvanced Science, EarlyView.
We present a stimulus‐replicating system combining a tactile sensor with a wearable Peltier thermotactile module and concentric electrotactile electrode. Signals encoding pressure and temperature drive the stimulators to reproduce mechano‐thermal cues on the skin. AlN/PDMS encapsulation and SA/LA PSA ensure mechanical compliance and thermal efficiency.

Self‐Assembly of Antigenic Peptide Nanofibrils Templates the Growth of Silica Nanoparticles for Nanovaccines

open access: yesAdvanced Science, EarlyView.
Antigenic peptides Aβ42 and E7 self‐assemble into nanofibrils; APTES and TEOS induce SiO2 NP formation on these fibrils to form SiO2@fibril nanovaccines, which activate BMDCs in vitro. In vivo, SiO2@Aβ42 fibril nanovaccines alleviate AD symptoms and clear Aβ42 plaques in APP/PS1 mice, and SiO2@E7 fibril nanovaccines inhibit tumor growth and promote ...

Hydrogen‐Stabilized Self‐Rectifying Memristor Arrays for Reliable Multilevel Synapses in Transformer‐Based Keyword Spotting

open access: yesAdvanced Science, EarlyView.
A non‐filamentary self‐rectifying HfO2/TiOx resistive random‐access memory integrates H2 annealing with an incremental step pulse with verify algorithm to achieve stable and linear analog conductance modulation. The device enables low‐current 6‐bit multilevel operation while suppressing sneak current in crossbar arrays. Implemented in Transformer‐based

Exploiting Bulk Photovoltaic Effect in a Polar Hybrid Perovskite Towards Self‐Powered Detection of Weak Ultraviolet Polarized Light

open access: yesAdvanced Science, EarlyView.
Benefiting from intrinsic polarization, DJ‐type 2D perovskite crystals deliver self‐powered polarization‐resolved photocurrent under weak polarized UV light via the bulk photovoltaic effect, showing a high anisotropic factor of 8. ABSTRACT Weak light detection is essential for achieving high‐performance photodetectors with minimal power consumption ...

Harmonizing Rigidity and Flexibility: Embedding COF Quantum Dots Into Extracellular Matrix Gel as Carbon Monoxide Depot for Acoustically Triggered Time‐Programmable Anti‐Infective Therapy

open access: yesAdvanced Science, EarlyView.
A rigid‑flexible integrated CO depot is engineered by embedding rigid COFQDs into a flexible ECM gel network. The rigid framework enables high‑capacity CO storage and sonodynamic bacterial killing, while the flexible ECM gel controls sustained CO release, collectively eradicating multidrug‑resistant infection and promoting scarless healing.
