Transparent conductive films comprising sparse metal conductive layers are processed after coating with an overcoat to lower the sheet resistance of the film. The sparse metal conductive layer can comprise a fused metal nanostructured network. A coating, such as a polymer overcoat or a polymer undercoat can noble metal ions that can further reduce the sheet resistance with the application of heat and optionally humidity. In particular, silver ions in a coating are demonstrated to provide important stabilization of sparse metal conductive layers, whether or not fused, upon the application of heat and humidity. A coating can further comprise a metal salt stabilization composition.

Apparatus, including a flexible insulating substrate, having a first side and a second side, rolled about an axis parallel to the substrate. The apparatus also includes a first conducting spiral that is right-handed relative to a normal to the substrate, and a second conducting spiral that is left-handed relative to the normal, formed on the first side of the substrate. The first conducting spiral has a first initial termination and a first final termination, the second conducting spiral has a second initial termination and a second final termination, the spirals have a displacement therebetween, with a preset magnitude so that when the substrate is rolled about the axis the first initial termination aligns with the second initial termination. The apparatus also has a via penetrating the substrate from the first side to the second side so as to interconnect the first initial termination and the second initial termination.

Implementations described and claimed herein provide thin film devices and methods of manufacturing and implanting the same. In one implementation, a shaped insulator is formed having an inner surface, an outer surface, and a profile shaped according to a selected dielectric use. A layer of conductive traces is fabricated on the inner surface of the shaped insulator using biocompatible metallization. An insulating layer is applied over the layer of conductive traces. An electrode array and a connection array are fabricated on the outer surface of the shaped insulator and/or the insulating layer, and the electrode array and the connection array are in electrical communication with the layer of conductive traces to form a flexible circuit. The implantable thin film device is formed from the flexible circuit according to the selected dialectic use.

Described herein is a catheter and method for catheter assembly. The flexible substrate includes a number of layers, where each layer has a number of printed wires. The printed substrate is environmentally protected. The printed substrate is rolled and inserted into the catheter. Connectors are attached to each end of the rolled substrate. The connectors are connected to sensors at a distal end of the catheter and with electrical cards or a cable connector at a proximate end of the catheter. At least one layer of the substrate is connected to a coil in a magnetic sensor. A layer in which the traces are shorted in the distal end is used to measure a magnetic interference. These measurements are used by a processor or hardware to cancel out the magnetic interference effect on the other layers. In an implementation, another printed substrate can be wrapped within the catheter shaft and used for non-magnetic type sensors.
