Elastin is Responsible for Tissue Elasticity01:12

Elastin is Responsible for Tissue Elasticity

3.4K
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

Elastic Strain Energy for Shearing Stresses

622
As discussed in previous lessons, strain energy in a material is the energy stored when it is elastically deformed, a concept crucial in materials science and mechanical engineering. This energy results from the internal work done against the cohesive forces within the material. When a material undergoes shearing stress and corresponding shearing strain, the strain energy density, which is the energy stored per unit volume, is calculated. Within the elastic limit, where the stress is...

Strain and Elastic Modulus01:15

Strain and Elastic Modulus

9.3K
The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...

Area of Science:

  • Biomedical Engineering
  • Biophysics
  • Dermatology

Background:

  • Assessing human skin viscoelastic properties is crucial for understanding skin health and disease.
  • Existing methods for measuring viscoelasticity can be invasive or lack precision.

Purpose of the Study:

  • To develop and validate a novel, non-invasive optical elastography technique for in vivo human skin viscoelastic property measurement.
  • To establish reliable viscoelastic models for skin characterization.

Main Methods:

  • Utilized geometrically focused surface (GFS) waves for wide bandwidth wave field measurements.
  • Applied an analytical solution to experimentally measured GFS waves to determine frequency-dependent surface wavenumber.
  • Related wavenumber to dynamic shear modulus and fitted various viscoelastic models to the dispersion curve.

Main Results:

  • The novel optical elastography method demonstrated efficacy in measuring skin viscoelasticity.
  • Fractional models showed the least variability in 'α' parameters (CVs of 0.15, 0.16).
  • Standard linear solid and fractional Voigt models provided the best fit (R² of 0.93, 0.89).

Conclusions:

  • The developed optical elastography technique is effective for in vivo skin viscoelastic property measurement.
  • Viscoelastic skin models derived from this method have potential for identifying skin diseases and evaluating treatment responses.
  • Further studies with larger cohorts are warranted to fully realize the clinical applications.
