Abstract: A combustible gas sensor that uses a resistively heated, noble metal-coated, micromachined polycrystalline Si filament to calorimetrically detect the presence and concentration of combustible gases. The filaments tested to date are 2 .mu.m thick.times.10 .mu.m wide.times.100, 250, 500, or 1000 .mu.m-long polycrystalline Si; some are overcoated with a 0.25 .mu.m-thick protective CVD Si.sub.3 N.sub.4 layer. A thin catalytic Pt film was deposited by CVD from the precursor Pt(acac).sub.2 onto microfilaments resistively heated to approximately 500.degree. C.; Pt deposits only on the hot filament. Using a constant-resistance-mode feedback circuit, Pt-coated filaments operating at ca. 300.degree. C. (35 mW input power) respond linearly, in terms of the change in supply current required to maintain constant resistance (temperature), to H.sub.2 concentrations between 100 ppm and 1% in an 80/20 N.sub.2 /O.sub.2 mixture. Other catalytic materials can also be used.

Abstract: A device for quantitatively measuring adherence of thin films provides a first substrate having an upper surface and a second substrate having a surface coplanar therewith. The second substrate is spaced on all sides from the first substrate by a cavity. The thin film is suspended over the cavity and adhered to the surfaces of the two substrates. A characteristic length of the area of the surface of the second substrate to which the film is adhered is made small relative to the characteristic length of the cavity. A pressure differential is applied across the thickness of the film such that the film debonds from the surface of the second substrate. Mechanical characteristics of the debonding of the film are observed and measured. The characteristics are thereafter related to provide a quantitative measurement of adherence of the thin film to the second substrate. A measurement of relative adherence between different films is obtained by testing a multilayered film structure. Other layers of various materials may be used to define a smaller area of adherence to which the film may be adhered.

Abstract: The invention overcomes limitations of conventional power and thermodynamic sources by with micromachinery components that enable production of significant power and efficient operation of thermodynamic systems in the millimeter and micron regime to meet the efficiency, mobility, modularity, weight, and cost requirements of many modern applications. A micromachine of the invention has a rotor disk journalled for rotation in a stationary structure by a journal bearing. A plurality of radial flow rotor blades, substantially untapered in height, are disposed on a first rotor disk face, and an electrically conducting region is disposed on a rotor disk face. A plurality of stator electrodes that are electrically interconnected to define multiple electrical stator phases are disposed on a wall of the stationary structure located opposite the electrically conducting region of the rotor disk. A first orifice in the stationary structure provides fluidic communication with the first rotor disk face at a location radially central of the rotor blades, and a second orifice in the stationary structure provides fluidic communication with the first rotor disk face at a location radially peripheral of the rotor blades. An electrical connection to the stator electrode configuration is provided for stator electrode excitation and for power transfer with the stator electrode configuration as the rotor disk rotates.

Abstract: There is provided an electrostatically-controllable actuator having a stationary electrode, with an actuating element separated from the stationary electrode by an actuation gap. The actuating element includes a mechanically constrained support region, a deflection region free to be deflected through the actuation gap, and a conducting actuation region extending from about the support region to the deflection region. A commonality in area between the actuation region and the stationary electrode is selected to produce controlled and stable displacement of the deflection region over a displacement range, e.g., extending to a specified point in the actuation gap, when an actuation voltage is applied between the actuation region and the stationary electrode. This range of stable displacement, which can be stable bending, can extend to a point greater than about ⅓ of the actuation gap, or even through the full actuation gap. As a result, the invention overcomes the limitation of ⅓ gap actuation of conventional electrostatic actuation configurations.
