Abstract
In this paper, we investigate the behaviour of biological tissues (skin) coupled to a flexible sensor embedded at a solid substrate based on a numerical model taking into account the relationship between strain/stress components at the interface. Based on this study, the most appropriate biomechanical factors are understood and quantified in order to optimize the sensor/biological tissue interface conditions. A micromechanical description based on a mathematical formulation has been developed to evaluate the biomechanical behaviour provided by a 2D viscoelastic model of Kelvin-Voigt. Based on the results, it appears that the model can be used effectively to characterize in-vivo the dynamic properties of soft tissues in order to adapt the biophysical properties of flexible sensors dedicated to optimal adhesion
