The purpose of this paper is to present a newly developed process for the fabrication of multilayer circuits based on the pad-printing technique. Even though the maturity level, in terms of accuracy, substrate type and print size of several printing industrial processes is relatively high, the fabrication complexity of multilayer printed electronic...

A more sensitive method than the train-of-four ratio seems required to detect low levels of residual neuromuscular blockade before tracheal extubation. The goal of the study was to determine the potential benefit of 5 s of 100 versus 200 Hz tetanic stimulation to quantify the residual block with mechanomyography in anesthetised patients. Twenty inf...

This paper presents the fabrication and characterization of a flexible, flat, miniaturized fluxgate sensor with a thin amorphous rectangular magnetic core fabricated by the pad/printing technique. Both the design and the various printing steps of the sensor are presented. The fluxgate sensor comprises of solenoid coils, and to the best of our knowl...

Objective: Translational studies on motor control and neurological disorders require detailed monitoring of sensorimotor components of natural limb movements in relevant animal models. However, available experimental tools do not provide a sufficiently rich repertoire of behavioral signals. Here, we developed a robotic platform that enables the mo...

Over the last decade, several distinct research groups tested possible uses of membrane contactors for the wine industry, notably for the management of dissolved gases in wines, adjustment of the CO 2 concentration while reducing the O 2 concentration at the same time. Other experiments were done with partial alcohol reduction and addition of N 2 t...

A flexible flat micro-Fluxgate sensor with amorphous rectangular core, fabricated using a simple printing technique is presented. All materials were selected to facilitate the fabrication process and to achieve optimal sensor performance. The device’s response to an externally applied magnetic field has been studied. The linear measuring range of t...

Nous présentons les résultats du développement d'un procédé d'impression d'encres conductrices et isolantes pour la fabrication de circuits imprimés. Ce procédé est basé sur une technique d'impression répandue dans le monde horloger : la tampographie. Il s'agit d'un procédé de fabrication additif pour la fabrication de circuits en petites à grandes...

Several azide-derivatized and fluorescently-labeled peptides were immobilized on azadibenzocyclooctyne (ADIBO)-activated slide surfaces via a strain-promoted alkyne-azide cycloaddition (SPAAC) reaction revealing excellent immobilization kinetics, good spot homogeneities and reproducible fluorescence signal intensities. A myc-peptide micro-array imm...
Article
Peptide and protein microarrays provide a multiplex approach to identification and quantification of protein–protein interactions (PPI), useful to study for instance antigen–antibody properties. Multivariate serology assays detecting multiple tumor auto-antibodies (TAA) is an emerging class of blood tests for cancer detection. Here we describe the...
Chapter
From an engineering point of view, the nervous system, which is made of neural tissue, is a most complex biological system. All possible instruments or tools for applications related to the nervous system are part of another type of complex systems: biomedical instrument systems. As in any interacting system, “communication” can occur at the interf...

We show the integration of a home-made interference optical microscope (IOM) with an Atomic force microscope, as well as the combination of IOM with a nanoindentor. Such combined instruments have many applications in the characterisation of MEMS/NEMS. As an illustrative example, we have used a MEMS accelerometer with capacitive read-out. Surface to...
Conference Paper
A novel carbon sensor array has been microfabricated for the spatially distributed measurement of biological Nitric Oxide (NO). NO is intrinsically involved in a large number of brain injury states, like stroke, besides performing a bioregulatory role. The distributed measurement of biological NO signals is expected to be a very useful tool for res...

Successful perfusion and survival of brain slices using a microfabricated fluidic interface chamber is demonstrated. Up to three chambers are fabricated on the same glass substrate using a standard photolithography process. Their base is filled with arrays of micropillars to replace the nylon mesh used in classical interface chambers. These micropi...
Conference Paper
A novel perfusion chamber for brain slice studies was developed, based on the Haas interface chamber principle. The 400-μm high chamber is integrated on top of a glass substrate using a standard microfabrication process and is filled with arrays of micropillars to confine and to hold the perfusion fluid within its 11 ×29 mm<sup>2</sup> area. The mi...

A simple temperature compensation method for inductive proximity microsensors based on the differential relaxation oscillator has been developed and successfully tested. With this compensation and for the temperature range from −20°C to +80°C, an accuracy better than ±10 μm at 1 mm distance to an aluminum target has been measured. The microsensor h...

The first fully integrated inductive proximity sensor has been realized with a 75 nH, 1 mm side gold electrodeposited squared coil and with on-chip 1 μm CMOS readout circuit. The measured nominal frequency output is of 8.95 MHz and increases up to 11.60 MHz with an aluminum target placed at 50 μm of the coil. The on-chip electronic interface is bas...

We analyse the problem of scaling down an inductive proximity sensor made of superposed multiple-turn flat coils. We scale down linearly all the geometrical dimensions. Then the nominal inductance is scaled down proportionally to the scale factor. The coupling factor of the superposed coils remains constant. However, for both ferromagnetic and non-...
