Title (EN) MICRO FLOW MEASUREMENT DEVICES AND DEVICES WITH MOVABLE FEATURES
(FR) DISPOSITIFS DE MESURE DE MICRO DÉBIT ET DISPOSITIFS AYANT DES ÉLÉMENTS MOBILES
Abstract:
(EN) Disclosed is a micro flow device including a body frame defining a chamber and having a first port and a second port into the chamber. A first membrane carrying a first electrode is disposed over a first face of the body frame and a second membrane carrying a second electrode is disposed over a second face of the body frame. An axle member is disposed in the chamber affixed to the first and second membrane and a wheel member is disposed in the chamber about the axle member and spaced from the axle element by a gap. An interrupter feature is formed on the wheel, with the interrupter feature causing a variation in capacitance between the first and second electrodes during rotation of the wheel. Also disclosed are techniques for providing freely rotating, sliding, moving, etc. features in devices fabricated by roll to roll processes.
(FR) L'invention concerne un dispositif de micro débit comprenant un cadre de corps qui définit une chambre et comprenant un premier orifice et un deuxième orifice dans la chambre. Une première membrane portant une première électrode est disposée sur une première face du cadre de corps et une deuxième membrane portant une deuxième électrode est disposée sur une deuxième face du cadre de corps. Un élément d'axe est disposé dans la chambre en étant fixé à la première et à la deuxième membrane, et un élément de roue est disposé dans la chambre autour de l'élément d'axe et espacé de l'élément d'axe par un écart. Un élément interrupteur est formé sur la roue, l'élément interrupteur provoquant une variation de la capacité entre les première et deuxième électrodes pendant la rotation de la roue. L'invention concerne également des techniques pour réaliser des éléments à rotation, coulissement, déplacement, etc. libre dans des dispositifs fabriqués par des procédés à rouleau contre rouleau.
