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.
Vertical Hall sensors are capable of measuring surface-parallel components of the magnetic field. They allow therefore relatively easy conception of single-chip multi-axial magnetic sensors compared to solutions using horizontal Hall plates. The modern tre ...
In this paper, we present a new planar fluxgate magnetometer structure. The sensor has the orthogonal fluxgate configuration which makes the detection part independent of the excitation mechanism. The sensor consists of a ferromagnetic cylindrical core cov ...
Modern applications in industry, navigation and medicine demand small and sensitive magnetic field sensors. In this thesis we have developed a new planar micro fluxgate magnetometer. High resolution, low power consumption and orthogonal fields detection ma ...
In this paper, we present a novel high resolution optical imaging device on chip. It is based on a line of nano holes defined in an optically opaque aluminum film on a CMOS imaging sensor chip. Because it's free of bulky optical elements and compatible to ...
In many applications, a Hall element is used for contact-less measurement such as linear and angular positions, electrical current, power and energy, etc. The Hall element fabricated by means of CMOS technology features mediocre characteristics [R.S. Popov ...
The paper deals with Hall and flux-gate magnetic field sensors consisting of integrated combination of CMOS ASICs and planar ferromagnetic components. Ferromagnetic parts are made of a soft amorphous alloy, integrated at the CMOS wafer in a post-processing ...
We present the first fully CMOS-integrated 3D Hall probe. The microsystem is developed for precise magnetic field measurements in the range from mT up to tens of tesla in the frequency range from DC to 30 kHz and with a spatial resolution of about 150 μm. ...
An electronic compass made of a new planar 2D micro-fluxgate sensor is presented. The magnetometer is integrated in a standard CMOS process, and uses a post-processed cross-shaped ferromagnetic amorphous core. This core is diagonally placed above a single ...
