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.

The present disclosure provides an article having a substrate having a first nanostructured surface and an opposing second surface; and a conductor micropattern disposed on the first surface of the substrate, the conductor micropattern formed by a plurality of traces. The micropattern may have an open area fraction greater than 80%. The traces of the conductor micropattern may have a specular reflectance in a direction orthogonal to and toward the first surface of the substrate of less than 50%. The nanostructured surface may include nanofeatures having a height from 50 to 750 nanometers, a width from 15 to 200 nanometers, and a lateral spacing from 5 to 500 nanometers. 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.

Inductively curable composition

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.

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.

Methods of patterning a conductor on a substrate

Metalized web substrate is wet etched in a reaction vessel by contacting with oxidizing and metal complexing agent to remove metal from unpatterned region. Following etching, substrate is rinsed, and rinse is at least partly recycled. Concentrations of oxidizing and metal complexing agents in the etchant bath are maintained by delivering replenishment feeds of each. Concentration of metal in the etchant bath is maintained by discharging some of the etchant bath. Replenishment rates of oxidizing and metal complexing agents and etchant removal rate are determined based at least in part on rate that metal etched from the substrate enters the etchant bath.
