“…2) includes a device for ensuring that a forearm is maintained perpendicular to the indenter, a pump that exerts pressure on an individual's forearm to minimize involuntary movements, and a mechanism to activate the muscle. Previously, the assembly was used to study in vivo the mechanical properties of human skin [28].…”

This study proposes in vivo tests and design of experiments to determine the influence of experimental factors on the mechanical response of the soft tissue. The experimental factors considered are: room temperature (A), indentation velocity (B), indenter temperature (C), pump pressure (D) and muscle activation (E). An inverse method was developed to obtain the constants for constitutive equations of a multilayer biological model (skin, hypodermis, and muscle) through the use of indentation tests in combination with a finite element method. For each combination of the experimental factors, two groups of constants were established from the inverse method. Sixteen combinations of experimental conditions and their corresponding constants for the Mooney-Rivlin constitutive equations were obtained to be used in further numerical models. The factor D and factor interactions ADE, CDE, and ACDE were statistically significant with respect to skin mechanical response. Therefore, it can be concluded that there is not a current equation able to represent the mechanical properties of the skin under all the experimental conditions considered in this study.

“…They used three springs in series to model their results using assumed thicknesses of each layer. Isaza and Ramirez investigated the effect of temperature and indenter diameter on this elastic Young's Modulus [39]. Álvarez-Asencio et al used a nano- any effect on its indentation properties [41], [42].…”

A diabetes infusion kit is a treatment option for patients with type one diabetes. Using beam springs, the device inserts a Teflon cannula into a patient's skin for delivery of insulin.Modelling the insertion process requires understanding of how the skin surface deforms and fractures. Experiments measuring the indentation properties and fracture properties of porcine skin were performed. A viscoelastic model was developed and fit to experimental indentation force results to derive material properties. A fracture toughness coefficient was derived from the
