  • Patent number: 8829766
    Abstract: An acoustic wave resonator device comprising a resonant layer that comprises a series of side-by-side areas of first and second dielectric materials. In one embodiment the first dielectric material is a piezoelectric, in particular the first dielectric material can be a piezoelectric and the second dielectric material can be non-piezoelectric. In another embodiment, the first dielectric material is a piezoelectric of first polarity and the second dielectric material is a piezoelectric of opposite polarity or different polarity. Where needed, the resonant layer is supported on a reflector composed of series of layers of high acoustic impedance material(s) alternating with layers of low acoustic impedance material(s). For example, the reflector comprises AlN, Al2O3, Ta2O5, HfO2 or W as high impedance material and SiO2 as low impedance material.

  • Publication number: 20080311434
    Abstract: A solid oxide fuel cell structure obtainable by selective electro-chemical processing, comprising an electrolyte membrane (4) formed by a thin film more than 50 nm but less than 10 ?m thick, covering a supporting structure (1) made of a bulk substrate, the supporting structure having at least one 100 ?m to 100 mm wide opening that is covered by the electrolyte membrane (4). A metallic grid (9) is applied over the electrolyte membrane (4) and serves at the same time as structural element to support the membrane and as current collector. The metallic grid (9) has gridlines that are higher than the membrane thickness and whose height to width ratio is larger than 0.5, and a mesh size about 10 to 1000 times smaller than the width of said opening. The metallic grid (9) can be applied on top of a patterned metallic sub-layer structure (7,7a) arranged for supplying a fine distribution of current and increasing the density of electrolyte-electrode boundaries exposed to the fluid.

  • Publication number: 20060125746
    Abstract: A microelectrical device has a ferroelectric layer (10) between parallel electrodes (20,21) at least one of which (21) is movable. The electrodes have a closed position in which the ferroelectric layer (10) is sandwiched between the two electrodes (21,21) and an open position in which the movable electrode (21) is spaced from the ferroelectric layer (10). A spring effect biases the movable electrode (21) towards the open position. When the movable electrode (21) is closed by a first voltage pulse (P1) the ferroelectric layer (10) is polarized to hold the movable electrode (21) closed. When zero voltage is applied the movable electrode (21) is held closed by remnant polarization of the ferroelectric material until the application of a second voltage pulse (P2) which cancels the remnant polarization of the ferroelectric material (10) to allow the movable electrode(s) to be moved to the open position by the spring effect.

  • Patent number: 6727113
    Abstract: Method for manufacturing a plurality of pyroelectric sensors by forming a thin pyroelectric film or layer on one face of a silicon wafer or substrate, wherein electric polarization of this film is provided between lower and upper electrodes defining pixels forming these sensors. In order to protect the wafer in the event of a short-circuit between two electrodes of a pixel, resistors are arranged in series with the lower or upper electrodes by connecting these electrodes to each other by subsets in order to carry out the electric polarization. Once this polarization has been carried out, the electric connections connecting the upper or lower electrodes are removed to allow each pixel to supply an elementary electric signal when the sensor is operating. In order to minimize the risk of short-circuits and in order to reduce the stray capacity of the electrodes, the upper and lower electrodes of the pixels are structured.

  • Publication number: 20030173519
    Abstract: The pyroelectric sensor includes a plurality of pixels (12A) each formed of a thin pyroelectric film (20A) and first and second electrodes (14, 28) arranged on either side of said film. The lower electrodes (28) are structured, i.e. they are micromachined so as to form electrodes belonging to the pixels so as to reduce the thermal cross-talk between the pixels. The pyroelectric film is porous. According to a preferred embodiment of the invention, the porous pyroelectric film is continuous and uniformly deposited on the sensor substrate. The porous films have reduced thermal conductivity, allowing sensors with a high level resolution to be obtained without requiring micromachining of the pyroelectric layer between the pixels.
