“…Both the ratio of the rapid elastic recovery to the elastic deformation (where U R /U E is defined as the elastic function) and the ratio of the rapid elastic recovery to the total skin deformation (where U R /U F is defined as relative elastic recovery) have been quoted in the literature (Escoffier et al 1989;Rodrigues 2001;Smalls et al 2006). The ability of skin to recoil is significantly reduced by both the intrinsic (Escoffier et al 1989;Smalls et al 2006;Takema et al 1994) and extrinsic ageing processes Smalls et al 2006;Staloff et al 2008;Takema et al 1994) and by exposure to UV-A and UV-B radiation in vitro (Takema and Imokawa 1998). In most studies, skin stiffness [as determined from a decrease in elastic (U E ) or total deformation (U F )] also increased significantly in both intrinsically (Escoffier et al 1989;Smalls et al 2006) and extrinsically aged tissue Smalls et al 2006;Takema et al 1994) and in UV radiation-exposed tissues (Takema and Imokawa 1998).…”

The ability of elastic tissues to deform under physiological forces and to subsequently release stored energy to drive passive recoil is vital to the function of many dynamic tissues. Within vertebrates, elastic fibres allow arteries and lungs to expand and contract, thus controlling variations in blood pressure and returning the pulmonary system to a resting state. Elastic fibres are composite structures composed of a cross-linked elastin core and an outer layer of fibrillin microfibrils. These two components perform distinct roles; elastin stores energy and drives passive recoil, whilst fibrillin microfibrils direct elastogenesis, mediate cell signalling, maintain tissue homeostasis via TGFβ sequestration and potentially act to reinforce the elastic fibre. In many tissues reduced elasticity, as a result of compromised elastic fibre function, becomes increasingly prevalent with age and contributes significantly to the burden of human morbidity and mortality. This review considers how the unique molecular structure, tissue distribution and longevity of elastic fibres pre-disposes these abundant extracellular matrix structures to the accumulation of damage in ageing dermal, pulmonary and vascular tissues. As compromised elasticity is a common feature of ageing dynamic tissues, the development of strategies to prevent, limit or reverse this loss of function will play a key role in reducing age-related morbidity and mortality.

“…At present, there is no standard procedure for skin strain analysis. Different techniques and technologies have been used to this end: magnetic resonance imaging (Tran et al, 2007), optical coherence tomography (Hendriks et al, 2006), ultrasound (Hendriks et al, 2003), 3-D scanning (Van den Herrewegen et al, 2014), multiple-view stereo matching (Thabet et al, 2014;Kimura et al, 2008), motion capture systems (Mahmud et al, 2010) and digital image correlation (DIC) (Staloff et al, 2008;Evans and Holt, 2009;Miura et al, 2012;Yoneyama, 2010;Obropta and Newman, 2016). At the same time, the procedure to calculate skin strain depends on the technology used.…”

“…At the same time, the procedure to calculate skin strain depends on the technology used. The most commonly used procedures for this purpose combine optical techniques with finite strain theory and the strain gauge rosette method (Obropta Jr., 2015;Evans and Holt, 2009;Miura et al, 2012;Staloff et al, 2008). The finite strain theory combined with 3-D digital image correlation (3D-DIC) has been shown to be the most accurate method as it provides the highest spatial resolution to measure the skin strain field during movement (Miura et al, 2012;Obropta Jr., 2015;Staloff et al, 2008).…”

Abstract.Today there is continuous development of wearable devices in various fields such as sportswear, orthotics and personal gadgets, among others. The design of these devices involves the human body as a support environment. Based on this premise, the development of wearable devices requires an improved understanding of the skin strain field of the body segment during human motion. This paper presents a methodology based on a three dimensional digital image correlation (3D-DIC) system to measure the skin strain field and to estimate anatomical lines with minimum deformation as design criteria for the aforementioned wearable devices. The errors of displacement and strain measurement related to 3-D reconstruction and out-of-plane motion are investigated and the results are acceptable in the case of large deformation. This approach can be an effective tool to improve the design of wearable devices in the clinical orthopaedics and ergonomics fields, where comfort plays a key role in supporting the rehabilitation process.

“…Tsukahara et al (3) evaluated the effect of the eye opening and closing motion on the wrinkle of the facial skin. Staloff et al (4), (5) performed the deformation measurement of the skin surface using two-dimensional digital image correlation. However, the influence of the strain on the formation of the wrinkle is not yet clear.…”

Strain measurements around the eye during the blink are performed for four human subjects in order to investigate the relationship between the wrinkle formation with aging and the strains by daily motion. In addition to the strain measurement, the moisture content, the flexibility and the elasticity of the skin surface are measured for investigating the skin condition. For observing the wrinkle formed on the facial skin, the replicas of the skin surfaces are also collected. Results show that the relationship between the wrinkle and the strain distribution at the inner corner of the eye is different from that at the corner of the eye. The results indicate that different methods for the corner of the eye and the inner corner of the eye are required for avoiding the wrinkle formation.
