Noise‐Tunable Memristor Enabling Programmable Probabilistic Neurons for Frequency‐Selective Time‐Series Signal Encoding

Advanced Materials, EarlyView.
Memristors offer tunable resistance and intrinsic instability, making them promising tunable noise sources. We propose a spiking‐rate‐programmable probabilistic neuron using a Ru/TaOx/Pt memristor, where resistance‐dependent noise enables frequency‐selective encoding.

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

Advanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

Advanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...

Shape Memory Polymer‐Based Flexible Pressure Sensor for Real‐Time Venous Thrombosis Monitoring

Advanced Materials Interfaces, EarlyView.
A shape‐memory tubular flexible pressure sensor with a 100‐mesh microstructured SMP‐PLA/MWCNTs sensing layer was developed for PICC‐mounted monitoring of thrombosis‐related pressure changes. The sensor combines high sensitivity (204 kPa−1), a fast response time (28 ms), and conformal catheter fixation and was validated by hydrostatic and ex vivo ...

Strain‐Activated Mechanical Metamaterial With Programmable Dual‐Phase Stiffness and Enhanced Energy Absorption

Advanced Materials Technologies, EarlyView.
A strain‐activated mechanical metamaterial is developed to achieve programmable dual‐phase stiffness through an intrinsic geometric locking mechanism. Finite element modeling and parametric analysis identify the key design parameters governing activation strain, stiffness transition, and energy absorption.
