Small, fast and tough: an overview of our silicone-based actuators

Herbert Shea, Samuel Rosset

At the Microsystems for Space Technologies Laboratory, EPFL, we design and manufacture miniaturised silicone-based dielectric elastomer actuators (DEAs). We love silicone, because even though the achievable strain is generally smaller than what you can get ...

Magnetic Model of the CERN Proton Synchrotron

Mariusz Juchno

In this thesis, we present development of the first magnetic model of the main Proton Synchrotron magnets. The operation of the machine and conducting research on increasing its performance require a significant amount of the magnetic field data for the op ...

A Flying Robot with Adaptive Morphology for Multi-Modal Locomotion

Dario Floreano, Ludovic Daler, Julien Jean Denis Nicolas Lecoeur, Patrizia Bernadette Hählen

Most existing robots are designed to exploit only one single locomotion mode, such as rolling, walking, flying, swimming, or jumping, which limits their flexibility and adaptability to different environments where specific and different locomotion capabili ...

Miniature Mobile Systems for Inspection of Ferromagnetic Structures

Patrick Schoeneich

Power plants require periodical inspections to control their state. To ensure a safe operation, parts that could fail before the next inspection are repaired or replaced, since a forced outage due to a failure can cost up to millions of dollars per day. No ...

The AirBurr: A Flying Robot That Can Exploit Collisions

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod, Adam Klaptocz

Research made over the past decade shows the use of increasingly complex methods and heavy platforms to achieve autonomous flight in cluttered environments. However, efficient behaviors can be found in nature where limited sensing is used, such as in insec ...

Ring magnets for magnetic beads trapping in a capillary

Hubert Girault, Anne-Laure Gassner

This paper introduces the concept of ring magnets for magnetic beads (MBs) trapping in a capillary. Such magnets enable an easy insertion of a capillary simply like a pearl on a string. With this system, high magnetic forces are obtained thanks to the prox ...

Miniature Magnetic Climbing Inspection Robots

Frédéric Rochat

Industrial plants have an abundance of complex and confined areas that require systematic inspection. Maintenance work is necessary to ensure reliability and safety. In many cases, due to either size limitations or high danger, access is impossible to huma ...

Magnetic Stationary Phases for Protein Adsorption

Anne-Laure Gassner

Magnetic beads (MB) have now proven to be a powerful tool in both research and biomedical applications. They are available in a wide range of sizes (from nm to several µm) and their surface can be modified with molecules having biological specificities and ...

Slotless Permanent-Magnet Machines: General Analytical Magnetic Field Calculation

Yves Perriard, Pierre-Daniel Pfister

This paper presents a general analytical model for predicting the magnetic field of slotless permanent-magnet machines. The model takes into account the effect of eddy currents in conductive regions and notably in conductive permanent magnets without negle ...

Nested Surface Coils for Multinuclear NMR

Rolf Gruetter

This article introduces the design of surface coils for multinuclear applications. The relative sensitivities of several NMR-visible nuclei of biological interest are considered, and the motivations to operate an RF coil at multiple frequencies, both seque ...
