2. Characterization of Silicones
Most analytical methods commonly used for organic materials also apply to silicones. Extensive reviews have been published about the different analytical techniques that are applicable for detecting and characterizing silicones [1]. The focus here will be on methods as they relate to typical application problems; some of these are commonly used methods. Others, such as elemental analysis and th...
متن کاملIn-vivo Measurement of Elasto-mechanical Properties of Soft Biological Tissues
We present a method to determine elasto-mechanical properties of soft biological tissues, and a device able to perform the required measurements in-vivo. The device permits the controlled application of vacuum to small spots of organic tissue and registers the small deformation caused, during the whole measurement process. Deformation is measured with a vision based technique and the grabbed im...
متن کاملLASTIC: A Light Aspiration Device for in vivo Soft TIssue Characterization
This paper introduces a new Light Aspiration device for in vivo Soft TIssue Characterization (LASTIC). This device is designed to be used during surgery, and can undergo sterilization. It provides interactive-time estimation of the elastic parameters. LASTIC is a 3cm x 3cm metallic cylinder divided in two compartments. The lower compartment is a cylindrical chamber made airtight by a glass wind...
متن کاملComparison of Lastic (light Aspiration Device for in Vivo Soft Tissue Characterization) with Classic Tensile Tests
LASTIC is a device estimating in vivo soft tissue elasticity. It uses negative pressure to deform the tissue surface and captures several deformation stages to trace the behavioral curve. Using Finite Element inverse analysis and a Neo Hookean constitutive law, the tissue’s Young modulus is evaluated. This paper compares LASTIC capabilities with standard tensile tests on four samples with elast...
متن کاملValidation of a Light Aspiration device for in vivo Soft TIssue Characterization (LASTIC)
In-vivo characterization of soft tissue is a key step towards accurate biomechanical simulation enabling planning and intra-operative assisted surgery. This chapter presents the new version of LASTIC, a device measuring soft tissue deformations using a negative pressure. Its capabilities are compared with standard tensile tests on five samples with different elastic properties, i.e Young modulu...
