The fibrous microstructure of human soft tissues is responsible for a complex mechanical behavior at the macroscopic scale, highly non-linear, anisotropic and visco-hyperelastic. Since the 1960s and the boom of “bionics”, a large field of research has been developed to mimic the materials and structures of evolving systems. Nowadays, the biomimetic approach is very promising for the treatment of soft-tissue pathologies, though it still needs important progress from fundamental research, in particular when it comes to biological oscillators such as vocal folds.
The global objective of this project is to design new fibrous synthetic composites mimicking the vocal-fold histological specificities, and to study their multi-scale mechanical and vibratory properties.
Three major experimental steps are carried out:
- PI: Lucie Bailly
- Co-PI: Nathalie Henrich Bernardoni
- PhD: Thibaud Cochereau
- GIPSA Lab
- LADAF (CHU Grenoble)
