Finger pad friction and tactile perception of laser treated, stamped and cold rolled micro-structured stainless steel sheet surfaces

Friction, 2017
Tactile perception is a complex system, which depends on frictional interactions between skin and counter-body. The contact mechanics of tactile friction is governed by many factors such as the state and properties of skin and counter-body.

Machine learning‐based investigations of the effect of surface texture geometry on the wear behaviour of UHMWPE bearings in hip joint implants

Biosurface and Biotribology, Volume 10, Issue 4, Page 143-158, November 2024.
Abstract The purpose of this research is to develop data‐driven machine learning (ML) models capable of estimating the specific wear rate of ultra‐high molecular weight polyethylene (UHMWPE) used in hip replacement implants. The results of the data‐driven models are demonstrating a high level of consistency with the experimental findings acquired from ...

EFFECT OF HYALURONIC ACID MOLECULAR WEIGHT ON FRICTION OF ARTICULAR CARTILAGE [PDF]

Proceedings on Engineering Sciences, 2019
Hyaluronic acid (HA) is among others one of the component of synovial fluid (SF) and is the main component which affects the rheology of SF. However, during various degenerative joint diseases like osteoarthritis, the concentration and molecular weight ...

Injectable Boron Nitride‐Hyaluronic Acid Hybrid Hydrogels to Facilitate Joint Motion: Mechanical and Tribological Characterization

Advanced Therapeutics, Volume 7, Issue 10, October 2024.
The lubricating property of hexagonal boron nitride (hBN) is used for the first time to facilitate joint mobility. The effect of increasing the addition of nanoparticle (BNPs) and nanosheet (BNNSs) structures on the CoF is discussed. BNNS doped hydrogel showed an 18.9% decrease in CoF compared to untreated hydrogel.

In-situ generated tribomaterial in metal/metal contacts: Current understanding and future implications for implants

, 2017
[EN] Artificial hip joints operate in aqueous biofluids that are highly reactive towards metallic surfaces. The reactivity at the metal interface is enhanced by mechanical interaction due to friction, which can change the near-surface structure of the ...
