Abstract:

This research project, in its fourth year, continues to contribute to the suite of instruments, models and data for describing soft biological tissues. Accomplishments include our first publication of our techniques and results in a major biomechanics journal the development of a useful and detailed model describing the poroviscous, hyperelastic character of tissues development of inverse techniques for the extraction of the characteristic parameters from this model, using existing pathological breast tissue data as a data source construction of a new large strain, moderate rate, high fidelity bench-top indentation system, improving on the variety of testing that can be performed adding a 3-D ultrasound scanning apparatus to measure 3-D strain fields during indentation developed new algorithms to measure the internal strain field from data with low signal to noise ratios. External collaborations have lead to analysis of the Truth Cube 2 results and comparison with additional techniques construction of prototypes of in vivo high speed testing devices with MIT which will be used for abdominal organ tissues, and design of an instrument for the measurement of porcine brain tissues and successful construction of a miniature force sensor that will be used on the laryngoscopic vocal tissue testing device.
