Course detail
Biomechanic Systems
FSI-ZBS Acad. year: 2022/2023 Winter semester
The subject provides theoretical and practical knowledge related to the design and function of selected biomechanical systems. The attention is paid to the understanding of the interaction of mechanics, tribology and biology. The lectures aim to ensure understanding of the connection between engineering and biological disciplines in a wider context. The course follows the subjects of the bachelor's study in the fields of the strength of material, machine design and material sciences. Teaching is carried out in collaboration with the Orthopaedic clinic of Faculty hospital Olomouc and the Faculty of Mechanical Engineering CTU in Prague.
