Presentation:
This platform enables mechanical characterization tests to be carried out on all types of materials, biomaterials or biological materials. Each sample can be analyzed by multi-scale and multidisciplinary studies. Indeed, on each sample, we can carry out fatigue and wear tests, structural or material characterization tests (traction/compression device, nanoindentation device). Finally, we can perform biochemical and histological experiments. This allows us to understand the microstructure of the material. We can also perform in vitro bioreactor tests with cells. This platform is associated with the expertise of clinicians, radiologists, mechanics and biologists. All these associated competencies are unique at regional and national level. The engineer school “Ecole Centrale de Marseille” brings all its experience on the characterization of implantable medical devices, as well as its expertise in the industrial world.
This platform directly located on an hospital site, will allow to carry out scientific studies for the benefit of patients. This platform is a technological response to clinical needs.
