    摘要: MEMs devices are integrally fabricated with included micro or nanoparticles by providing a mixture of a sacrificial material and a multiplicity of particles, disposing the mixture onto a substrate, fabricating a MEMs structure on the substrate including at least part of the mixture, so that at least some of the mixture is enclosed in the MEMs structure, removing the sacrificial material, and leaving at least some of the multiplicity of particles substantially free and enclosed in the MEMs structure. The step of fabricating a MEMs structure is quite general and is contemplated as including one or a multiplicity of additional steps for creating some type of structure in which the particles, which may be microbeads or nanobeads, are included. A wide variety of useful applications for MEMs integrated with micro or nanoparticles are available.

    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: 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.
