Perché au-dessus du village alpin de Leysin, l’ancien Sanatorium des Chamois a été construit en 1903. À l’abandon depuis 2002, cet édifice historique est depuis une ruine architecturale isolée dans le paysage. Elle fait face à la vallée, tout en ayant un r ...
Adaptive joints are structural joints made of materials with enhanced transduction properties that can vary their stiffness via solid-state actuation (e.g. thermal, mechanical). In this work, stiffness tuning is used to switch the joint between a ‘locked’ ...
Construite en 1971 par Georges-Jacques Haefeli à Neuchâtel, la Cité universitaire, fait partie du patrimoine moderne de la ville. Petite révolution pour l’habitat étudiant de la région, elle était imaginée comme un lieu de vie regroupant vie estudiantine e ...
Interest in the dielectric electroactive polymer is growing in the medical field because of the large similarity with the biological muscles. With the objective to create an artificial pump based on DEAP, this paper presents the concept of an innovative sp ...
Each of the four ITER Electron Cyclotron Heating Upper Launcher (ECHUL) features eight transmission lines (TLs) that are used to inject 170-GHz microwave power into the plasma at a level of up to 1.31 MW (at the TL diamond window) per line. The millimeter ...
The speed of change in the modern world is impressive. Within the last 50 years, many devices and technologies have significantly transformed their appearance, intrinsic characteristics and improved their performance. Computers have changed from the size o ...
Research interest into the miniaturisation of micro-robots has soared in recent years due to the availability of suitable integrated actuators. The reduction in size of these components is achieved through the implementation of Self-Sensing Actuation (SSA) ...
We present variable stiffness dielectric elastomer actuators (DEAs), combining a single DEA actuator with embedded shape memory polymer (SMP) fibers, which can be electrically addressed to locally reduce the stiffness by a factor of 100. The device accommo ...
Fast liquid jets are investigated for use as a needle-free drug delivery system into an elastic tissue such as skin. Using smaller jet diameters in a repetitive regime can mitigate bruising and pain associated with current injectors. In this study, we aim ...
Elastic gridshells comprise an initially planar network of elastic rods that are actuated into a shell-like structure by loading their extremities. The resulting actuated form derives from the elastic buckling of the rods subjected to inextensibility. We s ...
