The role of denatured synovial fluid proteins in the lubrication of artificial joints

, 2019
CoCrMo ball-on-flat wear tests were carried out with 25 wt% bovine calf serum (25BCS) and human synovial fluid (HSF) to investigate artificial joint lubricating mechanisms.

Robust low friction mechanism of HNT–PVPA composite coating based on microviscosity regulation

Friction
Reducing the coefficient of friction is a critical method for improving the service life and enhancing the efficiency of artificial implants. Maintaining a robust low-friction effect is essential for optimal artificial implant performance.

Effect of dynamic loading versus static loading on the frictional behavior of a UHMWPE pin in artificial biolubricants

Biosurface and Biotribology, 2017
To obtain reliable results from in vitro measurements on the tribological behavior of joint implant materials, the parameters of the measurements must simulate in vivo conditions.

Active control of finger sliding friction with different surface roughness in SDS solutions for underwater surface haptics

Friction
Underwater surface haptics based on friction modulation provide new concepts for immersive extended reality haptic technology. A previous study proposed a modulation method by using a voltage-controlled technique in saline solutions, demonstrating that ...

Osteoarthritis and Cartilage Biotribology

, 2022
Osteoarthritis (OA) involves deterioration of cartilage, including enzymatic degradation and mechanical damage, resulting in disruption of cartilage lubrication, which in turn gives rise to the progressive deterioration in the structure and function of the cartilage tissue.
