Magnetic resonant sensors for remote identification of objects

This article deals with the use of Magnetic Resonant Sensors (M.R.S) for the realisation of an identification system. Nowadays, the market of I.D. systems evolves versus magnetic tags as they bring some advantages like remote identification and removal of the need of handling.

Supply electronics for piezo actuators & motors

In previous editions of Flux Magazine, we have presented some of the range of piezo actuators developed by CEDRAT RECHERCHE. These actuators cover a whole range of displacements from a few centimetres to sub-micrometric distances and from low to ultrasonic frequencies.The fields of application are expanding rapidly and use the latest developments in electronics for their power supply and control.

Rosetta Midas Stage Atila space applications

The ROSETTA/MIDAS space mission intends to analyze the dust resulting from the Wirtanen comet using an Atomic Force Microscope (AFM). To scan the dust, an extremely fine mechanism able to produce displacement’s accuracy in the sub-micrometer range with a limited mass, is required. The only technology which can meet this specification is the piezoelectric actuator associated to capacitive displacement sensors, which displays several advantages : solid state design, which means no friction, noise limited by the driving electronic, ...

Design and evaluation of a piezo xy stage

The ROSETTA/MIDAS mission of the Europeans Space Agency (ESA) intends to study the dust collected from the Wirtanen comet using an Atomic Force Microscope (AFM). This instrument utilzes an XY piezoelectric stage to achieve precise positioning in two in-plane orthogonal directions, and a Z actuator to support the needles for the analyses of dust particles in the out-of-plane direction.

Progress In Magnetostrictive Sonar Transducers

Continous interest from the French Navy (DRET and CERDSM) has permitted significant improvements to magnetostrictive transducers in order to produce low-frequency high-power sonar sources. These improvements can be appreciated by looking at three transducers.
