摘要:
A hard, transparent coating for a substrate and associated method for coating is disclosed. The coating includes alternating layers of a soft coating and a hard coating. The coating further includes a sensor. The electrical resistivity of the sensor may be measured to determine if the coating has been degraded. The coating may further include a hydrophobic outer layer.

In a method for producing a sensor element, a silicon nanowire having a diameter less than 50 nm is contacted via at least two points by electrodes. The nanowire and the electrodes are arranged on one plane on a substrate. Catalytically active metal nanoparticles having a diameter in the range of 0.5-50 nm are deposited on the surface of an insulating substrate and the surface and the metal nanoparticles deposited thereon are exposed to a gas flow containing a gaseous silicon component at a temperature in the range of 300-1100° C., whereupon, during a time period in the range of 10-200 minutes, a nanowire of a length in the range of 5-200 μm projecting from the substrate is formed. The nanowire projecting from the surface of the substrate is deposited in one plane with one of the contact surfaces corresponding to the surface of the insulating substrate by applying a secondary substrate, and either the nanowire deposited on the insulating substrate is contacted at two different points by electrodes or the nanowire adhering to the secondary substrate is contacted at two different points by electrodes.

A sensor for detecting one or more materials includes a substrate, a passivation layer formed on the substrate, a self-resonant structure and a high surface area material disposed on the passivation layer. The self-resonant structure includes a planar spiral inductor and a plurality of planar interdigitated capacitor electrodes disposed within the passivation layer. The planar spiral inductor includes an electrically conductive trace formed on the substrate in a planar spiral pattern having at least two turns and an inter-winding space between parallel segments of the electrically conductive trace. The plurality of planar interdigitated capacitor electrodes are electrically connected to the electrically conductive trace of the planar spiral inductor and formed on the substrate within the inter-winding space of at least one outermost turn of the planar spiral inductor. The high surface area material includes a conformal polymer coating to increase a sensitivity to the one or more materials.

A filter assembly has a qualified filter element that filters fuel, a filter housing for the qualified filter element and a water-in-fuel sensor that senses presence of water in the filter housing. An electrical resistance of the water-in-fuel sensor changes based upon whether the qualified filter element is installed in the housing. A filter assembly can also have a plurality of magnetic elements disposed on at least one of the filter housing and the qualified filter element. A plurality of wires are disposed on at least the other of the filter housing and the qualified filter element. The control circuit determines that the qualified filter element is installed in the filter housing based on a change in the electrical current in the plurality of wires.

The present disclosure relates to a nanostructured palladium-based flammable gas detector synthesized using sonochemistry. The nanostructured palladium-based flammable gas detectors may use nanostructured sensing materials to allow reduction of power consumption, where the nanostructures reduce power consumption due to their large specific area and increased porosity. The nanostructures may increase the number of active sensing sites, allowing the surface energy to be high enough for sensing reactions to occur without requiring significant external thermal energy,
摘要:
In a method of detecting a leak in a water impermeable membrane applied on a roof substrate, an electrical potential is created between a conductive detector on top of the membrane and the roof substrate causing current to flow between the roof substrate and the conductive detector through moisture in any leak in the membrane. The membrane is attached to the roof support substrate by an intervening layer therebetween which can be a primer or an adhesive layer which is caused to be electrically conductive by the addition an electrically conductive material. This allows the conductor on the roof substrate to which the potential difference is applied to be attached onto the roof substrate and covered by the layer underneath the membrane.
