Measuring electro-adhesion pressure before and after contact

Herbert Shea, Sylvain Thomas Schaller

Electro-adhesion (EA) is a low-power, tunable, fast and reversible electrically-controlled adhesion method, effective on both conducting and insulating objects. Typically, only the electro-adhesive detachment force, i.e., the force required to separate an ...

Effects of resonator geometry and substrate stiffness on the tunability of a deformable microwave metasurface

Romain Christophe Rémy Fleury, Rayehe Karimi Mahabadi, Taha Goudarzi

Tunable metasurfaces can shift their resonant frequency through different approaches, one of which is applying mechanical deformations. Here, we show the effects of two key factors on the tunability of deformable metasurfaces; the resonator geometry and su ...

Finite element investigation of stability bracing force demands of steel moment resisting frame columns under cyclic loading

Meriton Beqiraj

This thesis examines the out-of-plane stability bracing of deep wide flange steel columns in moment resisting frames (MRFs) under cyclic loading. This is performed through a detailed continuum finite element analysis including a validation process and a pa ...

The development of a universal method for grasping objects of varying morphology, material and size in unstructured environments remains an unsolved challenge. There is no one 'universal' solution which can function with low positional precision, can grasp ...

Dynamics of falling films on the outside of a vertical rotating cylinder: waves, rivulets and dripping transitions

François Gallaire, Nicolas Igor Jacques Kofman

Falling liquid films on the underside of a plate or on the outside of a rotating cylinder are subject to a destabilizing body force. The evolution of the film topology is determined by interactions between the Kapitza and the Rayleigh-Taylor instability, l ...

At its most fundamental level, touch sensation requires the translation of mechanical energy into mechanosensitive ion channel opening, thereby generating electro-chemical signals. Our understanding of this process, especially how the cytoskeleton influenc ...

Elife Sciences Publications Ltd2016

Human beings like all organisms, are subject to a variety of diseases. Musculoskeletal diseases such as arthritis, that affect our muscles and bones, are particularly debilitating in that they considerably limit our ability to interact with our environment ...

EPFL2015

The clinical tests currently used to assess spinal biomechanics preoperatively are unable to assess true mechanical spinal stiffness. They rely on spinal displacement without considering the force required to deform a patient's spine. We propose a preopera ...

Restoring Natural Sensory Feedback in Real-Time Bidirectional Hand Prostheses

Silvestro Micera, Marco Capogrosso, Stanisa Raspopovic, Francesco Maria Petrini, Jacopo Rigosa, Marco Bonizzato

Hand loss is a highly disabling event that markedly affects the quality of life. To achieve a close to natural replacement for the lost hand, the user should be provided with the rich sensations that we naturally perceive when grasping or manipulating an o ...

American Association for the Advancement of Science2014

Many proteins in alive organisms have a domain structure providing them the possibility to reversible unfolding, which seems to play an essential role in those processes occurring in tissues which are controlled by mechanical cellular tension. In this work ...
