Fibrous Pressure Sensor with Unique Resistance Increase under Partial Compression: Coaxial Wet‐Spun TiO2/Graphene/Thermoplastic Polyurethane Multi‐Wall Multifunctional Fiber

open access: yesAdvanced Materials, EarlyView.
TGTMW fibers are designed to show a sharp resistance increase under pressure, as the multi‐wall structure in the transition region between compressed and uncompressed areas bends and forms microcracks. This design breaks the physical sensitivity limit of conventional fiber‐shaped pressure sensors, which usually show resistance reduction under pressure ...

Photocatalytic Aqueous Reforming of Methyl Formate

open access: yesAdvanced Materials, EarlyView.
A 3d‐metal Cu‐based atomically dispersed photocatalyst, supported on modified g‐C₃N₄, facilitates the photocatalytic selective hydrogen (7.5 mmol gcat−1 of hydrogen; nothing else than H2 and CO2) generation from methyl formate. This diverse system functions under mild conditions, providing high hydrogen yield, selectivity, and enduring stability ...

Ultrafast Electron Dynamics at the Water‐Modified InP(100) Surface

open access: yesAdvanced Materials Interfaces, EarlyView.
P‐rich indium phosphide is exposed to H2O at 200 °C, leading to water adsorption stabilized by hydroxyl groups. Time‐resolved two‐photon photoemission indicates an increase in electron lifetimes at the near‐surface conduction band minimum by at least an order of magnitude; this is correlated using Density‐functional theory to dampening of surface P ...

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

Biomechanical and Displacement‐Related Considerations in the Design of a 3D‐Printed Composite Energy‐Storage‐and‐Return Prosthetic Foot

open access: yesAdvanced Materials Technologies, EarlyView.
For the first time, Continuous Fiber‐Reinforced 3D printing is used to fabricate a foot prosthesis, exploring the flexibility in the design space granted by additive manufacturing, evaluating computationally and experimentally the effect of different design features on the mechanical and biomechanical response of the material, to locally tune the ...
