Chattez avec Graph Search
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.
Electrostatic discharge in quartz watches is becoming more and more important due to the use of plastic materials and tactile sensors. The discharge can lead to different type of dysfunction such as a simple reset, a latch-up, or the destruction of the ele ...
The watchmaking crisis of the nineteen-seventies in effect marked an interruption of scientific research into the working of mechanical watches. For the past few years, a revival of interest in these timepieces has given industrialists the financial resour ...
Electrostatic discharge (ESD) in quartz watches is becoming more and more important due to the use of plastic materials and tactile sensors. The discharge can lead to different type of dysfunction such as a simple reset, a latch-up or the destruction of th ...
A novel probe based on a commercial quartz tuning fork and a microfabricated cantilever is presented. The U-shaped cantilever with a monolithic tip is combined with the tuning fork in a symmetrical arrangement, such that each of the two legs of the cantile ...
The dynamic mode atomic force microscopy based on a microfabricated cantilever and a commercial quartz tuning fork was probed. The probe was self-sensing and self-actuating. The tuning fork performed the function of a force sensor. The amplitude and freque ...
A piezoelectric elastic fin micromotor based on a PbZr0.53Ti0.47O3 thin film driving a micromachined silicon membrane was fabricated and studied. The stator was characterized by interferometry, and a laser set-up was used to measure the angular velocity an ...
