Stretchable and Strain‐Tolerant Gold‐Coated Fibrous Biosensor for Superoxide Anion Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
A breathable, stretchable gold nanomesh–TPU fiber platform is developed via controlled electroless deposition, enabling uniform through‐thickness conductivity while preserving porosity. Functionalized with superoxide dismutase, the system achieves selective, real‐time electrochemical detection of superoxide with high sensitivity, mechanical durability,

Solid Particle‐Liquid Metal Mixtures for Robust High‐Current Interconnects in Stretchable Electronics and Soft Robotics

open access: yesAdvanced Materials Technologies, EarlyView.
Metallic microparticles dispersed in liquid metal interconnects mitigate electromigration‐induced failure by reconfiguring internal current density distributions. These fillers facilitate the growth of a robust, protective gallium oxide shell at elevated temperatures, shifting the failure threshold toward a thermal limit.

Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms

open access: yesAdvanced Materials Technologies, EarlyView.
3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...

Ultralow wear in boundary lubrication: A tribological study of Bi-alloyed steel under high normal loads and sliding speeds

open access: yesFriction
Wearless sliding friction in the lack of lubrication remains one of the primary goals of scientific research, as wear greatly reduces the life of mechanical components.
