BACKGROUND Collagenous tissues store, transmit and dissipate elastic energy during mechanical deformation. In skin, mechanical energy is stored during loading and then is dissipated, which protects skin from mechanical failure. Thus, energy storage (elastic properties) and dissipation (viscous properties) are important characteristics of extracellular(More)
Numerous tests have been used to elucidate mechanical properties of tissues and implants including tensile, compressive, shear, hydrostatic compression, and three-point bending in one or more axial directions. The development of a nondestructive test that could be applied to tissues and materials in vivo would promote the analysis of tissue pathology as(More)
Several new methods have been used to non-destructively evaluate the mechanical properties of materials and tissues including magnetic resonance elastography, ultrasound elastography, optical coherence elastography, and various forms of vibrational analysis. One of the limitations of using these methods is the need to establish a relationship between the(More)
Recently, we have reported use of Optical Coherence Tomography (OCT) and vibrational analysis to determine the resonant frequency of a material from which the moduli of decellularized dermis, pig skin, silicone rubber and chemically modified dermis were calculated. In this paper, we present data on viscoelastic mechanical properties of extracellular(More)
