摘要:
L'invention concerne un dispositif de déplacement d'au moins un petit volume de liquide (5) sous l'effet d'une commande électrique, comprenant un substrat (1) pourvu de premiers moyens électriquement conducteurs (2), le dispositif comprenant également des deuxièmes moyens électriquement conducteurs (3) disposés en vis-à-vis des premiers moyens électriquement conducteurs (2), les premiers moyens électriquement conducteurs et les deuxièmes moyens électriquement conducteurs pouvant être reliés à des moyens d'alimentation électrique pour permettre l'application de forces électrostatiques au petit volume de liquide (5). Les deuxièmes moyens électriquement conducteurs comprennent au moins un fil conducteur (3) disposé parallèlement au substrat et à une distance déterminée du substrat pour permettre le déplacement du petit volume de liquide (5) le long dudit fil conducteur (3) sous l'effet des forces électrostatiques appliquées.
摘要:
The invention concerns a microfluidic device for handling a non-magnetic liquid, comprising at least a cell including: a chamber for confining a magnetic liquid (5) non miscible with the non-magnetic liquid (7) to be handled, magnetic means (6) associated with the chamber for locally applying to the magnetic liquid a magnetic field whereof the energy profile has a depression causing by discharge of the magnetic liquid, at least a volume for receiving non-magnetic liquid, the magnetic field being capable of displacement to enable handling of the non-magnetic liquid between inputting means (3) and evacuating means (4).

The invention concerns a photoacoustic spectrometer comprising: an infrared source (4, 18) produced in a first semiconductor substrate (4); a filter produced by a second semiconductor substrate (6); a micropit (12) formed in a third semiconductor substrate; a microphone (14, 34, 38) produced by the third semiconductor substrate and a fourth semiconductor substrate (10).
摘要:
The invention relates to a lab-on-a-chip comprising a fluidic system which is provided in a substrate, a fluid inlet which is connected to the fluidic system and a fluid outlet which is connected to the fluidic system. The aforementioned substrate comprises a plane layer (53) containing the fluidic system and an electrospray nozzle (65), said electrospray nozzle overhanging the rest of the substrate (51, 52). Moreover, the electrospray nozzle comprises a channel (64) having one end which is connected to the fluidic system and another end which forms the above-mentioned fluid outlet, said channel being equipped with electric conduction means (59) forming at least one electrode.
