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.
In this thesis work we propose new concepts of transporting and manipulating magnetic particles on microfluidic scale. The objective is to propose solutions to the problems related to the integration of the magnetic inductive components within a microfluid ...
We present the microfabrication and characterisation of a ball valve micropump in glass, which is magnetically actuated using the sinusoidal current of an external electromagnet. We employ the use of a simple powder blasting technology for microstructuring ...
A technology for the fabrication of bismuth Hall sensors integrated on SU-8 cantilevers has been developed in this project. Hall sensors with active area of 2 x 2 μm2 (Fig.2) are produced with lift-off and resized to 200 x 200 nm2 (Fig.3) with the FIB. SU- ...
Precise positioning over a long stroke is required in various fields. Important advances in the field of electromagnetic motors, piezoelectric actuators and bearing technology allow nanometric and sub-arc-second resolution for linear or rotary actuators, r ...
This paper presents a simple and low-cost prototyping technology for the realization of integrated micropumps in polymethylmethacrylate (PMMA). The three-dimensional (3D) micropumps consist of stacks of structured PMMA layers, which are either realised wit ...
We report on a high-sensitive SQUID-susceptometer for magnetization studies on two-dimensional electron systems (2DES). It consists of a low-noise thin-film dc SQUID and a wire-wound first-order gradiometer and is operated inside a superconducting 10 T-mag ...
We present an original concept of manipulation of magnetic microbeads in a microchannel. It is based on the dynamic motion of a self-assembled structure of ferrimagnetic beads that are retained within a microfluidic flow using a local alternating magnetic ...
