US Classification:

345174, 345176, 178 1805

Abstract:

A touch screen sensor includes a visible light transparent substrate and an electrically conductive micropattern disposed on or in the visible light transparent substrate. The micropattern includes a first region micropattern within a touch sensing area and a second region micropattern. The first region micropattern has a first sheet resistance value in a first direction, is visible light transparent, and has at least 90% open area. The second region micropattern has a second sheet resistance value in the first direction. The first sheet resistance value is different from the second sheet resistance value.

International Classification:

B44C 1/22

US Classification:

216 67, 216 11, 216 41

Abstract:

A method of patterning a conductor on a substrate includes providing an inked elastomeric stamp inked with self-assembled monolayer-forming molecules and having a relief pattern with raised features. Then the raised features of the inked stamp contact a metal-coated visible light transparent substrate. Then the metal is etched to form an electrically conductive micropattern corresponding to the raised features of the inked stamp on the visible light transparent substrate.

US Classification:

324686, 29829

Abstract:

Capacitive sensing devices are provided that include a sensing pattern of conductive traces disposed upon the surface of a substrate and a first passive circuit element that includes a metallic conductor disposed upon the same surface of the substrate. In some embodiments, the first passive circuit element is a component of an electronic circuit that can be, for example, a low pass filter. Provided capacitive sensing devices are useful, for example, when incorporated into projected touch screen display panels for use on electronic devices.

H01Q 1/38

US Classification:

235492, 343700 MS

Abstract:

Antennas suitable for use in RFID devices include an insulating substrate and a first conductive micropattern disposed on or in the substrate, the first conductive micropattern defining a contiguous mesh conductor. The first conductive micropattern forms an antenna responsive to at least a frequency of 915 MHz, and includes interconnected traces having a trace width in a range from 0.5 to 20 microns. Furthermore, the first conductive micropattern is characterized by an open area fraction of at least 80% or 90%. RFID devices include such an antenna and an integrated circuit configured to transmit and receive signals using the antenna. Cards, such as financial transaction cards or identification cards, include such an antenna carried by a card layer.

Abstract:

The present disclosure provides an article having (a) a substrate having a first nanostructured surface that is antireflective when exposed to air and an opposing second surface; and (b) a conductor micropattern disposed on the first surface of the substrate, the conductor micropattern formed by a plurality of traces defining a plurality of open area cells. The micropattern has an open area fraction greater than 80% and a uniform distribution of trace orientation. The traces of the conductor micropattern have a specular reflectance in a direction orthogonal to and toward the first surface of the substrate of less than 50%. Each of the traces has a width from 0.5 to 10 micrometer. The articles are useful in devices such as displays, in particular, touch screen displays useful for mobile hand held devices, tablets and computers. They also find use in antennas and for EMI shields
