    摘要： Methods and systems for improving the sensitivity of a variety of conductivity sensing devices, in particular capacitively-coupled contactless conductivity detectors. A parallel inductor is added to the conductivity sensor. The sensor with the parallel inductor is operated at a resonant frequency of the equivalent circuit model. At the resonant frequency, parasitic capacitances that are either in series or in parallel with the conductance (and possibly a series resistance) is substantially removed from the equivalent circuit, leaving a purely resistive impedance. An appreciably higher sensor sensitivity results. Experimental verification shows that sensitivity improvements of the order of 10,000-fold are possible. Examples of detecting particulates with high precision by application of the apparatus and methods of operation are described.

    摘要： A method (and resulting structure) for fabricating a sensing device. The method includes providing a substrate comprising a surface region and forming an insulating material overlying the surface region. The method also includes forming a film of carbon based material overlying the insulating material and treating to the film of carbon based material to pyrolyzed the carbon based material to cause formation of a film of substantially carbon based material having a resistivity ranging within a predetermined range. The method also provides at least a portion of the pyrolyzed carbon based material in a sensor application and uses the portion of the pyrolyzed carbon based material in the sensing application. In a specific embodiment, the sensing application is selected from chemical, humidity, piezoelectric, radiation, mechanical strain or temperature.

    摘要： An integrated composite beam structure. The structure has a substrate, which includes a surface and a thickness defined underlying the surface. The substrate is composed of a first material. A thickness of polymer based material includes a first portion, a length, and a second portion. The second is coupled to a portion of the substrate. The length is defined between the first portion and the second portion. The structure also has a spring constant (K) of less than a predetermined amount (e.g., 10 N/m, 1 N/m) characterizing the length of the polymer based beam structure. The first portion is capable of moving in a first direction characterized by the spring constant upon application of an externally applied force and is substantially fixed in a second direction, which is normal to the first direction. The second end is capable of returning to a predetermined state when the externally applied force has been removed. The second portion includes a selected geometric configuration to secure the second portion to the portion of the substrate.
