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 ...

A Hydro‐Expansive and Degradable Biomaterial Enabling Shape Recovery of Film‐Based Devices in Biofluids

open access: yesAdvanced Materials, EarlyView.
A chitosan‐based bio‐composite exhibits stable and strong tensile strength during volumetric expansion in body fluids, serving as a functional coating that enables a thin film‐based device to self‐flatten from its tubular shape required for catheter delivery.

Development of a Sensitive Electrochemical Aptasensor for Non‐Small Cell Lung Cancer Extracellular Vesicle Detection

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel electrochemical aptasensor enables the selective detection of lung cancer‐derived EVs by targeting the CD44 surface marker. The sensor uses a self‐assembled monolayer (SAM) for aptamer immobilization and achieves label‐free EV detection through electrochemical impedance spectroscopy.

Targeted Local Delivery via Fiber‐Embedded Flexible Microchannels Integrated with Film‐Based Implantable Probes

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, a fiber‐embedded drug delivery channel for implantable microprobes, demonstrating the first functional drug delivery system using flexible LCP‐based probes, is developed. The design incorporates fibers for site‐selective drug delivery and electrical functions. The utilization of monolithic thermal bonding simplifies fabrication.

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 ...

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

open access: yesAdvanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.
