Deep Eutectic Solvent‐Enhanced PEDOT: PSS/NR Foam Piezoresistive Sensor for High‐Sensitivity Wearable Devices and Sleep Monitoring Applications

Advanced Materials Interfaces, EarlyView.
A high‐performance piezoresistive foam sensor is developed by integrating natural rubber, PEDOT: PSS, and a deep eutectic solvent (DES). DES effectively detaches insulating PSS from PEDOT, dramatically amplifying electrical conductivity and sensitivity.

The Cohesion and Angle of Internal Friction and the Change of These Values in the Landslide Face

Landslides, 1980
The clay layer in the landslide face is about 3mm thick. Accordingly, the constants of shearing strength are as follows;c'≈0.φ'>0The reason is that the shearing conditions of sliding face are not consolidated-undrained but consolidateddrained. Therefore, the safety factor of landslide face can be expressed as;Fs=tanφ'∑ (W cos θ-uw) /∑W sin θThe pore ...

Leveraging Mechanical Resonances for the Selection of Promising Materials in Complex Phase Spaces

Advanced Materials Technologies, EarlyView.
A central challenge in materials science is the design of new functional materials with enhanced performance for targeted applications. This paper demonstrates that “listening” to materials through measuring their mechanical resonances is a rich, and largely untapped, platform for the rapid identification of promising novel compounds and a powerful ...

Comparative Study on Determining the Internal Friction Angle for Sand

, 2014
Shear strength is the main mechanical property which governs the stability and resistance of soil massifs. Practically in most cases failure occurs by concentration of plastic deformations in the form of shear bands along which the movement of a part of the massive develops as a result of exceeding the shear strength.

ANGLE OF INTERNAL FRICTION OF THE GRANULAR MATERIAL AND A SIMPLE TRANSIENT PHENOMENON

Transactions of the Japan Society of Civil Engineers, 1966
In the first part of this paper, relationships between the angle of internal friction and the void in cases of axial symmetry and plane strain were derived by the theory of mechanics of granular material due to the present author.With available data of shearing test on sand, the validity of these formulae mentioned above was examined, the results of ...

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.
