Biosensing and actuation for microbiorobots

Mahmut Selman Sakar

In this paper, we describe how signaling networks and actuation in bacterial cells and biomolecular networks of bacteria can be used to develop an integrated micro-bio-robotic system. SU8 microstructures blotted with swarmer cells of Serratia Marcescens in ...

A New Passive Methodology for Reducing the Noise in Electrical Machines: Impact of Some Parameters on the Modal Analysis

Dimitri Torregrossa, Christophe Espanet

This paper presents a 3-D finite-element modal analysis to reduce the acoustical power radiated by a brushless permanent-magnet synchronous machines and avoid any resonance phenomena. The method is able to analyze the impact of some design parameters on al ...

Tunable thin film bulk acoustic wave resonator based on BaxSr1-xTiO3 thin film

Nava Setter, Paul Muralt, Alexander Tagantsev

A tunable membrane-type thin film bulk acoustic wave resonator (TFBAR) based on a Ba0.3Sr0.7TiO3(BST) thin film has been fabricated. The resonance and antiresonance frequencies of the device can be altered by applying a dc bias: both shift down with increa ...

New slip synthesis and theoretical approach of CVT slip control

Yves Rothenbühler

Today's vehicle must be efficient in terms of gas (CO2, NOx) emissions and fuel consumption. Due to improvements in material and oil, the continuous variable transmission (CVT) is now making a breakthrough in the automotive market. The CVT decouples the en ...

Application of ultrasonic motors to MR-compatible haptic interfaces

Dominique Chapuis

Functional Magnetic Resonance Imagery (fMRI) is an imaging technique allowing the observation of brain activity. Haptic interfaces can be used in conjunction with fMRI to stimulate the subject while measuring brain activity. Using robotic stimulation over ...

Multistage hydraulic gas compression/expansion systems and methods

Alfred Rufer

Multistage hydraulic systems and methods for converting the potential energy of a pressurized gas, particularly air, into mechanical work operating in motor, and for producing compressed gas from the mechanical work of the rotating shaft (A1.1 ) when rotat ...

A Haptic Interface with Motor/Brake System for Colonoscopy Simulation

Hannes Bleuler, Evren Samur, Lionel Flaction

Training for colonoscopy, which is the examination and treatment of the colon, is often performed on real patients once the physician has passed the novice level. This increases the risk to the patient and lengthens the procedure time. Since a decade ago, ...

Multiphysic Modeling of a Hybrid Propulsion System for a Racecar Application

Alfred Rufer, Philippe Barrade

A hybrid propulsion system has been designed for an optional use in the Formula S2000, based on supercapacitive energy storage coupled to an ICE engine via a Synchronous PM machine. Because of the high level specification of the weight penalty in competiti ...

Multi Mobile System

MMS design allowing to move several cabins vertically, without counterweights. The vertical motion is performed with linear synchronous motors having stators distributed along the shafts and supplied by sectors. A simplified analytic approach developped at ...
