A Spare Support Vector Machine Based Fault Detection Strategy on Key Lubricating Interfaces of Axial Piston Pumps

open access: yesIEEE Access, 2019
Fault detection of axial piston pumps is of great significance to improve the reliability and life of fluid power systems. However, it is difficult to detect multiple faults on key lubricating interfaces due to the liquid-solid coupling.

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Compact Planar Low‐Voltage Electroadhesion Pads for Reversible Tissue and Hydrogel Adhesion

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents a planar, low‐voltage electroadhesion (LVEA) pad with reversible adhesion to tissues and anionic hydrogels at 10 V or less. On‐demand adhesion and release of a biological tissue using a single surface contact has been realized. Geometric design of the electroadhesion pad is investigated through experimental and computational methods ...
