Qualitative Study on the Regular Stick-Slip Shear Behavior of Ellipitical Particles
, 2009 本研究以橢圓形顆粒相對錯動關係來模擬碎屑顆粒間的剪力及膨脹行為，主要依據顆粒間的力平衡及相互爬升幾何膨脹變位關係，建立一套適合橢圓狀顆粒剪動行為之理論模式，以探討夾層顆粒所引起的剪力反覆升降滯動行為。研究結果顯示：在低正向應力環境下，顆粒間的相互爬升運動可定性解釋規則性滯動現象之一種原因；滯動曲線中每個循環平均剪動位移與顆粒的粒徑大小有關 ...

A Pressure Microsensor Made of Parylene‐C for Use as Medical Implant
Advanced Materials Technologies, EarlyView.A monolithic parylene‐C pressure sensor with gold strain gauges provides 6.2 μV$\mu{\rm V}$·mmHg$\cdot{\rm mmHg}$−1$^{-1}$ sensitivity. The morphology of a sputtered thin film strain sensor is granular/columnar, which results in a high gauge factor of 7.5. Thermal bonding and parylene‐C coating create a hermetic cavity.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics
Advanced Materials Technologies, EarlyView.A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Journal of Rock Mechanics and Geotechnical EngineeringThe thermal effect has a significant impact on the activation and slip characteristics of fractures. In this study, four pairs of granite fractures were treated by temperatures T ranging from 25 °C to 900 °C. The fractures were then employed to carry out
