Multimode Hydraulically Amplified Electrostatic Actuators for Wearable Haptics

Herbert Shea, Ronan Julien Hinchet, Edouard Franck Vincent Gustave Leroy

The sense of touch is underused in today’s virtual reality systems due to lack of wearable, soft, mm-scale transducers to generate dynamic mechanical stimulus on the skin. Extremely thin actuators combining both high force and large displacement are a long ...

Delicate yet strong: characterizing the electro-adhesion lifting force with a soft gripper

Herbert Shea, Jun Shintake, Vito Cacucciolo

Compliant grippers are one of the most promising soft robotic devices for industrial tasks. Soft grippers dramatically simplify grasping control because the gripper automatically conforms to the object's shape. A common limitation of soft structures is tha ...

Active microrheology in corrugated channels

Ignacio Pagonabarraga Mora

We analyze the dynamics of a tracer particle embedded in a bath of hard spheres confined in a channel of varying section. By means of Brownian dynamics simulations, we apply a constant force on the tracer particle and discuss the dependence of its mobility ...

Stiffness, force and drift capacity of in-plane loaded modern unreinforced brick masonry walls

Bastian Valentin Wilding

In countries of low to moderate seismicity, such as Switzerland, unreinforced masonry (URM) is mainly used in residential buildings due to its good insulation capacity and fire resistance along with a fair compressive strength. URM walls however show a lim ...

Measurement of the dynamics in ski jumping using a wearable inertial sensor-based system

Kamiar Aminian, Julien Favre, Julien Chardonnens

Dynamics is a central aspect of ski jumping, particularly during take-off and stable flight. Currently, measurement systems able to measure ski jumping dynamics (e.g., 3D cameras, force plates) are complex and only available in few research centres worldwi ...

Marangoni induced force on a drop in a Hele Shaw cell

François Gallaire, Philippe Meliga

We analyse the force balance on a cylindrical drop in a Hele-Shaw cell, subjected to a Marangoni flow caused by a surface tension gradient. Depth-averaged Stokes equations, called Brinkman equations, are introduced and a general closed form solution is obt ...

Dependence of the most probable and average bond rupture force on the force loading rate: First order correction to the Bell-Evans model

Giovanni Dietler, Serguei Sekatski, Fabrizio Benedetti

The Bell-Evans model which predicts the linear dependence of the most probable intermolecular bond rupture force on the logarithm of stretching force loading rate is usually used to discuss the dynamic force spectroscopy experiment data. This model is cons ...
