Patent number: 8339764Abstract: A MEMS device comprises first and second opposing electrodes (42,46), wherein the second electrode (46) is electrically movable to vary the electrode spacing between facing first sides of the first and second electrodes. A first gas chamber (50) is provided between the electrodes, at a first pressure, and a second gas chamber (52) is provided on the second, opposite, side of the second electrode at a second pressure which is higher than the first pressure. This arrangement provides rapid switching and with damping of oscillations so that settling times are reduced.Type: GrantFiled: May 7, 2009Date of Patent: December 25, 2012Assignee: NXP B.V.Inventors: Peter G.

Publication number: 20120305374Abstract: A MEMS switch in which at least first, second and third signal lines are provided over the substrate, which each terminate at a connection region. A lower actuation electrode arrangement is over the substrate. A movable contact electrode is suspended over the connection regions for making or breaking electrical contact between at least two of the three connection regions and an upper actuation electrode provided over the lower actuation electrode. The use of three of more signal lines enables a symmetrical actuation force to be achieved, and/or enables multiple switch functions to be implemented by the single movable electrode.Type: ApplicationFiled: November 29, 2011Publication date: December 6, 2012Applicant: NXP B.V.Inventors: Martijn Goossens, Hilco Suy, Peter Gerard Steeneken, Klaus Reimann

Publication number: 20120238473Abstract: A sensor device is disclosed, which depends on discrimination in time between groups of binding events of target particles to nano-electrodes. The target particles may be in the liquid phase or in suspension. The nano-electrodes form part of a sensor arrangement having a plurality of sensors. The sensor device is arranged such that different species of target particles arrive at the nano-electrodes at different times, using techniques such as chromatography or application of a field such as an electric, magnetic, or gravitational field. The particles may be labelled or unlabeled. The invention is particularly suited, but not limited, to sensing bioparticles.Type: ApplicationFiled: March 14, 2012Publication date: September 20, 2012Applicant: NXP B.V.Inventors: Evelyne Gridelet, Hilco Suy, Filip Frederix

Publication number: 20120099753Abstract: A microphone has a membrane (20) mounted to vibrate in response to pressure fluctuations, a backplate (30) facing the membrane and being more rigid than the membrane, and circuitry (95) for sensing the vibrations relative to the backplate, the backplate being prestressed and having a geometry such that a response of the backplate to structure borne vibration matches a corresponding response of the membrane. This can help reduce or minimize relative movement between these surfaces caused by structure borne vibration and hence improve the signal-to-noise ratio of the microphone. The geometry can be a hub and spoke arrangement.Type: ApplicationFiled: April 6, 2010Publication date: April 26, 2012Applicant: KNOWLES ELECTRONICS ASIA PTE.

Publication number: 20120091546Abstract: A microphone comprises a substrate (20), a microphone membrane (10) defining an acoustic input surface and a backplate (11) supported with respect to the membrane with a fixed spacing between the backplate (11) and the membrane (10). A microphone periphery area comprises parallel corrugations (24) in the membrane (10) and backplate (11). By using the same corrugated suspension for both the membrane and the backplate, the sensitivity to body noise is optimally suppressed.Type: ApplicationFiled: April 20, 2010Publication date: April 19, 2012Applicant: KNOWLES ELECTRONICS ASIA PTE.

Publication number: 20120048709Abstract: The present invention provides a capacitive MEMS device comprising a first electrode lying in a plane, and a second electrode suspended above the first electrode and movable with respect to the first electrode. The first electrode functions as an actuation electrode. A gap is present between the first electrode and the second electrode. A third electrode is placed intermediate the first and second electrode with the gap between the third electrode and the second electrode. The third electrode has one or a plurality of holes therein, preferably in an orderly or irregular array. An aspect of the present invention integration of a conductive, e.g. metallic grating as a middle (or third) electrode. An advantage of the present invention is that it can reduce at least one problem of the prior art. This advantage allows an independent control over the pull-in and release voltage of a switch.Type: ApplicationFiled: May 7, 2010Publication date: March 1, 2012Applicant: NXP B.V.Inventors: Peter Gerard Steeneken, Hilco Suy, Rodolf Herfst, Twan Van Lippen
