FRIA Grant - Tunable Stiffness Mechanisms
This research project aims at studying controllable stiffness mechanisms (mainly for tubular systems). Some applications indeed require to alternate between a flexible state (e.g. to follow a path) and a rigid one (e.g. force transmission). Such variation in stiffness is required for applications in robotics, in active control for mechatronics, in aerospace and in biomedical field. Among these applications, the case study chosen for this PhD project is related to catheters used for instance in case of vascular occlusions, transbronchial biopsy or interventional gastroenterology. The questions to answer are to know stiffness order of magnitude and variation range, control stimuli and design rules.
