Silicon microcantilevers with MOSFET detection

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 ...

Modeling and Control of a Magnetically Levitated Planar Motor

Alireza Karimi, Roland Longchamp, Marc Kunze, Vincent Reymond

This paper deals with the modeling and control of a magnetically levitated planar motor. The actuator considered has moving coils and stationary magnets. The principal objective is to develop a model which can be implemented in simulation. Therefore, the d ...

Phase Field Modelling Of Twinned Dendrite Growth

Michel Rappaz, Jean-Luc Desbiolles, Mario Alberto Salgado Ordorica

Twinned dendrite growth has been found to occur in aluminum alloys when critical thermal conditions (G approximate to 100 K/cm, nu(s) approximate to 1 mm/s) and a slight convection in the melt are present during directional solidification. Split in their t ...

Strength of the baseplate fixation of a reversed shoulder prosthesis

Stephanie Kochbeck

A reversed shoulder prosthesis is the general treatment of glenohumeral arthritis and concomitant rotator cuff arthropathy. However, failure due to loosening of the components remains a concern. The purpose of this study was to examine the forces that occu ...

A hybrid ultrasonic motor and electrorheological fluid clutch actuator for force-feedback in MRI/fMRI

Hannes Bleuler, Dominique Chapuis, Roger Gassert, Etienne Burdet

This paper presents a safe, electrically powered MR-compatible actuator with a large range of output impedance, which can be used at the entry of the scanner bore. This actuator is composed of an ultrasonic motor (USM) and a torque-controlled electrorheolo ...

Mechanical characterization of a dielectric elastomer microactuator with ion-implanted electrodes

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on the mechanical characterization and modeling of a non-prestretched dielectric elastomer diaphragm microactuator with ion-implanted electrodes under the influence of a distributed load (pressure). Thin polydimethysiloxane (PDMS) membranes (30 u ...

Two-dimensional electrostatic force field measurements with simultaneous topography measurement on embedded interdigitated nanoelectrodes using a force distance curve based method

Patrik Willi Hoffmann, Christian Santschi

Accurate simultaneous measurements on the topography and electrostatic force field of 500 nm pitch interdigitated electrodes embedded in a thin SiO2 layer in a plane perpendicular to the orientation of the electrodes are shown for the first time. A static ...

Evaluating the influence of induced passive torques in the simulation of time-varying human poses

Ronan Boulic

In the computerized generation of human poses, it is important to take into account not only the active component of the torque, but also the ligaments and connective tissues which produce a passive torque at the limits of the joint range of motion. We pre ...
