    摘要: A system and method for measuring the biomechanical properties of a healing wound in a specimen which utilize a chamber for applying an increasingly negative pressure over time to an area of tissue containing the wound, markings on the area for facilitating measurement of expansion of the area, a pressure measurement device for measuring the pressure in the chamber as a function of time, one or more cameras for obtaining multiple views of the area over time, a digitizer for generating a digital representation of each of the views, and a processor for determining a strain value from each digital representation and for correlating each strain value with a pressure measurement corresponding to the same point in time to provide a stress-strain relationship.

    摘要: The invention relates to a novel device for measuring in a quantitative manner surface properties, especially of tissues such as human skin, comprising a probe to be placed on said surface, means for applying a predetermined weight to said surface via said probe, means for removing the weight and means for measuring the change of height against time of the surface when the weight is removed. The probe may also be applied by suction and a force may be applied to it, tending to lift it from said surface, determining the change of height of the surface when said force is applied. The invention further relates to a method for determining surface properties, and especially elasticity, compressibility, viscosity, humidity and stretchability of human skin and for determining the effects of various cosmetic preparations on human skin.
