Abstract: A pliable pressure sensitive sensor device and method of making the same is provided. The sensor includes first and second pliable protective layers, which cover sets of conductive fibers that spatially separated by an electrically conductive pliable layer, which deforms in response to a pressure event. The fiber sets form a grid pattern and are in electrical communication with sets of electrical contacts located in predetermined locations along the fibers. In response to a pressure event in proximity to the contact, the pliable layer deforms and increases the amount of surface area in contact with an electrical contact whereby an electrical resistance at an individual electrical contact decreases in response to the pressure event.

Abstract: The present invention provides a semi-quantitative lateral flow assay device and method for generating semi-quantitative data from a lateral flow assay. The device comprises a thin, porous hydrophilic substrate wherein the substrate includes a star-shaped or other geometry taken in plan view having a liquid sample-receiving central region and multiple arms that extend or radiate out from the central region. Each arm includes a reaction zone formed by the presence of an analyte-capturing agent wherein the reaction zone of each arm is located at a different distance from the central region such that the analyte in the sample is captured accumulates in different quantities at at least some of the reaction zones of the arms in a manner that can be analyzed to yield semi-quantitative data from lateral flow assays.

Abstract: A lateral flow device includes a porous medium layer having a two-dimensional shape in plan view that is capable of supporting near-constant velocity capillary-driven fluid flow and can be combined with electrodes in a manner to achieve to achieve electrokinetic molecule separation.

Abstract: The present invention relates to a method of classifying charged molecules such as proteins for quantitative analysis. An analyte solution of the molecules is subjected to separational forces may be fluid drag and electrophoretic force in opposition. The analyte solution may be subjected to a two-phase process. The two-phase process may add both electrophoretic force based upon molecule charge, and differential mobility resistance based upon molecule mass and/or size.

Abstract: A lateral flow device includes a porous medium layer having a two-dimensional shape in plan view defined by one or more peripheral edges wherein the two dimensional shape includes a plurality of testing regions separated from one another by spaces between portions of the one or more peripheral edges. The porous medium layer further includes a fluid-receiving region in capillary flow communication through the porous medium layer to the testing regions.
