Abstract	The analysis of the mechanical properties of human skin in vivo is an essential parameter for the optimization of surgical operations in terms of cutaneous tissues. This paper presents an experimental device that was developed at FEMTO-ST institute for evaluating the skin response to different loadings. The ultra-light extensometer developed was tested in a uniaxial extension on a phantom material. The results obtained were successfully compared with those of a conventional tensile test device. The user-friendly interface allows the definition of diverse load and discharge sequences. The results of the tests on human subjects are consistent with the hyperelastic and viscous behavior of the cutaneous tissue in vivo. Thanks to its size, weight and stand-alone capabilities, the device is suited for local measurements in most of human body zones. This study provides an experimental tool for investigating human skin behavior in vivo. Further researches are being directed towards identifying the strain fields of human skin by means of a biaxial extensometer and an imaging module.
