Fluctuations of the Casimir-like force between two membrane inclusions

Anne-Florence Raphaëlle Bitbol

Although Casimir forces are inseparable from their fluctuations, little is known about these fluctuations in soft matter systems. We use the membrane stress tensor to study the fluctuations of the membrane-mediated Casimir-like force. This method enables u ...

A novel verticalized reeducation device for spinal cord injuries, the WalkTrainer: from design to the clinical trials

Reymond Clavel, Mohamed Bouri, Yves Stauffer, Jacques Fournier, Yves Allemand

Robotic assistive devices have been developed and are now being introduced in clinical environments. Such robots can advantageously provide long raining, with quantifiable mobilization (force and position). But in the event of a complete lesion the patient ...

Silicon microcantilevers with MOSFET detection

Luis Guillermo Villanueva Torrijo

We report the fabrication of silicon microcantilevers with MOSFET detection, to be used in force measurements for biomolecular detection. Thin cantilevers are required for a high force sensitivity. Therefore the source and drain of the transistors have bee ...

Development of a 2-DOF Electrostatic Haptic Joystick for MRI/fMRI Applications

This paper describes the development of a 2-DOF electrostatic haptic joystick designed for neuroscience studies in an MRI/fMRI. The joystick is fabricated using non-magnetic materials and actuated by two high-power electrostatic motor units which produce v ...

Probing nanomechanical properties from biomolecules to living cells

Giovanni Dietler, Sandor Kasas

Atomic force microscopy is being increasingly used to explore the physical properties of biological structures. This technique involves the application of a force to the sample and a monitoring of the ensuing deformation process. The available experimental ...

Physical properties and interactions of biomolecules

Mélanie Favre

The aim of this thesis was to explore the statistical physics and the mechanical properties of individual biomolecules, to study their interactions, and to develop new techniques based on atomic force microscopy (AFM). First, we exploit the high resolution ...

Electrostatic Glass Motors

This Master project concerns the electrostatic motors and focus essentially on the transverse force producing the torque. A study of this force is done with a glass sample and an electret sample under different input parameters such as the applied voltage, ...

The Casimir force in the semi-classical regime

The present thesis is devoted to a detailed study of the Casimir force exerting between two parallel metallic plates whose conducting behaviour is described on the microscopic level. In the semi-classical regime, which corresponds to large separations and ...

Analyzing an electromechanical actuator by Schwarz-Christoffel mapping

Yves Perriard, Marcel Jufer, Miroslav Markovic

We present an application of the conformal mapping (CM) method to determine the magnetic field and force in an electromechanical actuator. First, we show how to find, using a special type of CM known as the Schwarz-Christoffel mapping, the magnetic field i ...
