摘要:
L'invention concerne un procédé de fabrication d'un dispositif micro-fluidique, ledit dispositif comprenant un substrat (1) en polymère thermoplastique présentant une face dite supérieure (10) et un premier circuit micro-fluidique qui comporte au moins une ouverture (12, 122) débouchant sur ladite face supérieure (10), et un composant (2) portant des plots (24) agencés pour venir s'ancrer dans ledit substrat (1) en périphérie de ladite ouverture (12), ledit procédé comportant les étapes suivantes : - Chauffage pour que les plots d'ancrage (24) du composant (2) atteignent une température au moins égale à la température de transition vitreuse du substrat (1) ; - Fixation du composant sur le substrat (1) par enfoncement puis ancrage de ses plots (24) dans le substrat (1) ;
摘要:
A method for producing at least one deformable membrane micropump including a first substrate and a second substrate assembled together, the first substrate including at least one cavity and the second substrate including at least one deformable membrane arranged facing the cavity. In the method: the cavity is produced in the first substrate; then the first and second substrates are assembled together; then the deformable membrane is produced in the second substrate.
摘要:
The invention provides a device for the gravimetric detection of particles in a fluid medium, comprising a flat electromechanical oscillator (1), means for supporting the oscillator, means (15a, 15b, 15c, 15d) for actuating said oscillator and, on either side of the plane of the oscillator (1), two cavities (3, 5) enabling the oscillator (1) to vibrate when it is activated by the actuation means (15a, 15b, 15c, 15d), characterized in that at least one of the two cavities (3, 5) forms an integral part of a channel (2, 4) for the passage of a fluid over at least one of the faces (1a, 1b) of the oscillator and in that said actuation means (15a, 15b, 15c, 15d) take the form of at least one electrode (15a, 15b, 15c, 15d) lying in the same plane as that of the electromechanical oscillator and at a defined distance (g) from the oscillator, so as to ensure that the oscillator vibrates in its plane.
