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.
We present a study of the influence on Youngs modulus, stress and electrical conductivity of poly-dimethylsiloxane membranes implanted with titanium ions at energies from 5 to 35 keV, with doses up to 8x10^16 ions/cm2. The motivation for this study was to ...
Micro-system for active vibratory insulation, characterised in that it comprises a stand which includes a frame (1) and at least two beams (2a, 2b) which interlock and carry or are intended to carry an element requiring stabilisation (3), said beams (2a, 2 ...
Periodic arrays of shunted, piezoelectric patches are employed to control waves propagating over the surface of plate structures, and corresponding vibrations. The shunted, piezoelectric patches act as sources of impedance mismatch, which gives rise to int ...
The development of wireless and mobile communication in the last decade led to the elaboration of new components based on thin films with continually increasing performance and reduced fabrication cost. A fundamental element for mobile communication is the ...
Here we present the detection of ultralow concentrations of biomolecules in a device made from a polycarbonate membrane containing a network of gold nanowires and using a “contactless” impedance tomoscopy technique. The sensor comprises a thin dielectric l ...
Electrochemical acetoxylation has been widely investigated about 40 years ago. However, there are only a limited number of studies in non-aqueous electrolytes, mainly because of difficulties related with the extremely low electrical conductivity of organic ...
This thesis presents the fabrication and design of an impedance imaging sensor, and its application to monitoring in-vitro skin culture. Three-dimensional tissue cultures are becoming increasingly important in biological and medical research. There is, how ...
A sensor for measuring adsorption on a substrate has been designed including a contactless detection scheme, called supercapacitive admittance tomoscopy (SCAT). The sensor comprises a thin dielectric layer with two parallel band electrodes on the one side ...
In their article, ‘‘AC frequency characteristics of coplanar impedance sensors as design parameters’’, Hong et al.1 present an analytical model for the calculation of the resistance between two electrodes in a microchannel. However, their measurements fit ...
A conductive composite photoresist has been developed for the direct photopatterning of electrodes. It is based on a dispersion of silver nanoparticles in SU8, a non-conductive, negative-tone photoresist. Manufactured structures have an electrical conducti ...
