Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The “Modulated Friction Inertial Drive (MFID) principle” is presented as a locomotion solution for mmsize micro robots dealing with both size constraints and limitations in terms of power consumption. Based on one of the configurations of this locomotion p ...
We demonstrate the detection of a molecular beam by means of a micromechanical momentum transfer detector operated in vibrational resonance. With a sensitive surface area of 0.5x0.3 mm(2) the small paddle allows us to detect a beam with 6.5x10(7) He atoms ...
We investigate numerically the spectrum of plasmon resonances for metallic nanowires with a nonregular cross section, in the 20-50 nm range. We first consider the resonance spectra corresponding to nanowires whose cross sections form different simplexes. T ...
A new mass spectrometer of the omegatron type has been designed and tested. This new device, which we have called the resotron, combines the extremely low permanent outgassing and pumping rates of the omegatron (less than 10-11 torr liter/sec. and 10-3 lit ...
We investigate numerically the spectrum of plasmon resonances for metallic nanowires with a non-regular cross-section in the 20-50 nm range. After briefly recalling the physical properties of metals at optical frequencies, we point out the intrinsic diffic ...
NOVELTY - The microscope (11) has a set of four actuators (14, 16, 18, 20) i.e. piezoelectric actuators, and a strain gauge coupled to two opposed actuators (14, 18), arranged in opposed push or push-pull configuration to measure the differential motion of ...
This paper presents a method to detect the position of a linear actuator without any position sensor. The actuator winding has a resonance frequency that is very related to the position of the linear actuator moving part. A sinusoidal scan voltage is super ...

DC bias dependent acoustic resonance phenomena have been observed in micromachined tunable thin film capacitors based on Ba0.3Sr0.7TiO3 (BST) thin films. The antiresonance frequency is only weakly dc bias dependent, whereas the resonance frequency exhibits ...

The detection of higher modes of oscillation in atomic force microscopy can provide additional information on sample properties. However, the limited bandwidth of the photodiode in the beam deflection detection technique often limits the detectable frequen ...
Piezoelectric ZnO coatings on optical fibers are of interest for active optical-fiber devices such as phase and wavelength modulators. Reactive magnetron sputtering has been used to prepare high-resistivity [001] radially oriented ZnO coatings on 85 mm lon ...
