應用：

Systems for objective, quantitative and sensitive analyses of the biomechanical properties of skin, soft tissues, wound closure, wound healing & both intact and disruptive characterization of elastic materials.
 

SRLI’s patented technologies offer scientific value for R&D evaluations:

• Bridges methodology between the laboratory & clinic.
• Objective analysis for standardization & reproducibility.
• Fixed boundaries & minimal pre-stress for reliable analysis.
• Characterization and measurements of structural and material properties.
• Generous high-resolution deformation measurement range to detect ultra-sensitive differences.
• Non-Disruptive/Intact measurements of human skin, wounds & elastic materials.
• In-vivo biomechanical measurements of wound closure & the early phases of wound healing.
• Disruptive in-vivo elastic materials testing and analysis.
• Reduced sample preparation time allows for immediate testing (i.e. tissue adhesives & sealants)
• Non-Disruptive measurements permit multiple analyses of the same wound/tissue over time.
• Clinically relevant multi-axial stress in full thickness models.
• Intact materials characterization of the “actual product” 
  (no sample excision), including non-destructive testing.
• Provides data & results in real-time.
