Abstract:
A biomedical sensor system is disclosed that includes a plurality of electrodes (50) and a contiguous adhesive material (52) that is in contact with each of the plurality of electrodes. The adhesive material has a high impedance and is dielectric yet changes its dielectric properties in the presence of biomedical signals. The adhesive material may include a polymeric material and a polar material that is dispersed within the polymeric material. The system may be adapted for ECG analysis.
Abstract:
A method of forming an electrically conductive composite is disclosed that includes the steps of providing a first dielectric material and a second conductive material that is substantially dispersed within the first dielectric material; and applying an electric field through at least a portion of the combined first dielectric material and second conductive material such that the second conductive material undergoes electrophoresis and forms at least one electrically conductive path through the electrically conductive composite along the direction of the applied electric field.
Abstract:
An electrically conductive multilayer composite comprises first and second polymeric films, each being flexible and having upper and lower surfaces, with the second films being thermoformable at temperatures at and above its glass transition temperature. A flexible electrically conductive layer is applied to the upper surface of the first films, and an adhesive interlayer adheres the lower surface of the first film to the upper surface of the second film. The adhesive inter layer has elastic properties sufficient to accommodate relative movement between the thus adhered films occasioned by flexure of the composite.

Abstract:
A labeling composite and methods of producing and using same. The label has an information receiving first layer having a top surface onto which information is provided and a bottom surface. An adhesive second layer is provided on the bottom surface which accommodates the adherence of the first layer to a surface of a substrate, the adhesive second layer including substrate marking substance dispersed therein. The marking substance serves to mark the portions of the substrate surface covered by the second layer in a non-uniform manner providing a detectable image of the information upon removal of the composite of the first and second layers from the substrate surface.
Abstract:
A silicone release laminate formed by a support layer (11) with a silicone release layer (13). A separate pressure-sensitive silicone adhesive layer (12) may be on the same side of the support as the release layer, or on opposite sides of the support. The force required to separate the adhesive from the release layer is less than about 100 grams (3.3 oz.) per inch, and preferably less than 50 grams (1.7 oz.) per inch. The release layer is formed from one or more organopolysiloxanes having a viscosity below 1000 centipoises, and preferably below about 600 centipoises, with a high degree of cross-linking. The organopolysiloxanes may be produced directly by hydrolysis of organo-substituted halosiloxanes and depolymerization; or by hydration of higher molecular weight organopolysiloxanes and heat treatment to produce lower weight constituents.
