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.
