20120196053 | METHODS FOR CREATING AN ELECTRICALLY CONDUCTIVE TRANSPARENT STRUCTURE - Creating an electrically conductive transparent structure. Liquid droplets comprising electrically conductive nanomaterial are deposited randomly onto a surface of a supporting substrate at a desired density to form an electrically conductive transparent network wherein the droplets are released from an applicator. A rate of drying of the liquid is controlled such that the liquid is able to evaporate without substantially damaging the supporting substrate. | 08-02-2012 |
20130029481 | TEMPLATED CIRCUITRY FABRICATION - A method of making templated circuitry employs a template system that includes a template of an insulator material on a carrier having a conductive surface. The template includes multiple levels and multiple regions, wherein a first level exposes the conductive surface of the carrier. A first metal is electrochemically deposited on the conductive surface in first regions of the first level. A circuit material is deposited to cover the first metal. The template is etched until a second level of the template exposes the conductive surface in second regions on opposite sides of the first regions. A second metal is electrochemically deposited on the conductive surface in the second regions. The template of deposited materials is transferred from the carrier to a substrate. | 01-31-2013 |
20130187670 | CAPACITIVE SENSORS AND METHODS OF FABRICATION - Apparatus and methods related to capacitive sensors are provided. Metal walls are formed in an interdigitated pattern. A dielectric material corresponding to a selected analyte is deposited in contact with the metal walls thus defining a capacitive sensor. Exposure to the analyte causes the electrical capacitance to vary in accordance with intensity. Analyte detection or measurement, data acquisition, or other operations can be performed by way of the capacitive sensors of the present teachings. | 07-25-2013 |
