Abstract: An electronic device such as a wristwatch may be provided with conductive structures. The conductive structures may include a sensor electrode for an electrocardiogram (ECG) sensor. A coating may be disposed on the sensor electrode to reflect particular wavelengths of visible light so that the sensor electrode exhibits a desired color. The coating may include adhesion and transition layers on the sensor electrode, an opaque coloring layer on the adhesion and transition layers, and a thin-film interference filter on the opaque coloring layer. The thin-film interference filter may have an uppermost diamond-like carbon (DLC) layer. The DLC layer may contribute to the color response of the coating while concurrently minimizing noise in ECG waveforms gathered by the ECG sensor using the sensor electrode.

Abstract: An electronic device such as a power charger may include a conductive contact that conveys power signals. A coating may have adhesion and transition layers on the contact. The coating may have a thin-film interference filter having an uppermost layer that includes diamond-like carbon (DLC). If desired, the thin-film interference filter may have additional DLC layers stacked under the uppermost layer. The DLC layer(s) may include nitrogen to optimize corrosion resistance. The DLC layer(s) may include first and second metal dopants such as tungsten and chromium to optimize the electrical resistance and conductivity of the coating. The coating may exhibit a deep black, grey, and/or blue color.

Abstract: Non-cosmetic quality aluminum substrates are given a cosmetic finish by applying a PVD coating to the substrate. An enclosure for an electronic device can include an aluminum substrate including a 6000 series aluminum or 7000 series aluminum, a PVD coating disposed on the substrate, and a protective underlayer disposed between the aluminum substrate and the PVD coating.

Abstract: An electronic device may be provided with conductive structures such as conductive housing structures. A visible-light-reflecting coating may be formed on the conductive structures. The coating may have adhesion and transition layers, an opaque coloring layer on the adhesion and transition layers, and a three-layer thin-film interference filter on the opaque coloring layer. The three-layer thin-film interference filter may have an uppermost SiC layer, a lowermost SiCrCN layer, and a CrC layer interposed between the SiC layer and the SiCrCN layer. The opaque color layer may be a CrSiCN layer. The coating may exhibit a light violet color that has a relatively uniform visual response even when the underlying conductive structures have a three-dimensional shape.
