Abstract
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.
