The application discloses a security mark consisting of a plurality of layers, of which the cover layers are highly conductive films and the layers of the card core are films of varying transparency. One layer carries information, which can be read directly, if desired, above a security print, while the transparent conductive layer has an additional security markings, such as biometric or product identifiers marking which can be read conductively only with the aid of a special reader. All the layers consist of polymers, papers or mixtures which can be fused together to form a laminate which is fused together. The conductive layers form conductive traces which may be formed with single-walled or multi walled nano tubes or they can be formed from multiple layers or dispersions containing, carbon nano tubes, carbon nano tubes / antimony tin oxide, carbon nano tubes / platinum, or carbon nano tubes / silver, carbon, silver or carbon nano tubes / silver-cloride. An alternative layer can be formed from a separate conductive layer or suitable dispersion and the encoding accomplished by overlaying a nonconductive trace.

A sensor system that detects a current representative of a compound in a liquid mixture features a multi or three electrode strip adapted for releasable attachment to signal readout circuitry. The strip comprises an elongated support which is preferably flat adapted for releasable attachment to the readout circuitry; a first conductor and a second and a third conductor each extend along the support and comprise means for connection to the circuitry. The circuit is formed with single-walled or multi walled nanotubes conductive traces and may be formed from multiple layers or dispersions containing, carbon nanotubes, carbon nanotubes / antimony tin oxide, carbon nanotubes / platinum, or carbon nanotubes / silver or carbon nanotubes / silver-chloride. An active electrode formed from a separate conductive carbon nanotubes layer or suitable dispersion, positioned to contact the liquid mixture and the first conductor, comprises a deposit of an enzyme capable of catalyzing a reaction involving the compound and preferably an electron mediator, capable of transferring electrons between the enzyme-catalyzed reaction and the first conductor. A reference electrode also formed from a conductive carbon nanotube layer or suitable dispersion is positioned to contact the mixture and the second conductor. The system includes circuitry adapted to provide an electrical signal representative of the current which is formed from printing conductive inks made with nano size particles such as conductive carbon or carbon / platinum or carbon / silver, or carbon nanotubes / antimony tin oxide to form a conductive carbon nanotube layers. The multiple-electrode strip is manufactured, by then applying the enzyme and preferably the mediator onto the electrode. Alternatively the electrode can have a carbon nanotubes / antimony tin oxide, carbon nanotubes / platinum, or carbon nanotubes / silver or carbon nanotubes / silver-chloride surface and or a conductive carbon or silver ink surface connecting leg. The carbon nanotube solution is first coated and patterned into electro shapes and the conductive carbon nanotubes, carbon or silver ink can be attached by printing the ink to interface with the carbon nanotube electro surface. A platinum electrode test strip is also disclosed that is formed from either nano platinum distributed in the carbon nanotube layer or by application or incorporation of platinum to the carbon nanotube conductive ink.

The invention relates to a transparent, electrically conductive, biaxially oriented, single- or multilayer polyester film which includes a coating composed of (a) conductive (ITO) indium tin oxide particles or (ATO) antimony tin oxide particles, or of a mixture of these. The film further include other conductive components (b). The other conductive components (b) may be present either in the coating including ITO particles and / or ATO particles or in a layer in contact therewith. The conductive component (b) may also be a metal layer in contact with the ITO and / or ATO. The film is only oriented or relaxed prior to application of the ITO and / or ATO coating. The invention further relates to a process for the production of the film, and its use.
