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 and a multi-layer thin-film interference filter on the adhesion and transition layers. The multi-layer thin-film interference filter may have an uppermost SiCrN layer, a lowermost TiN layer, and a set of SiN layers interleaved with a set of SiH layers. The coating may exhibit an orange, yellow, or red color that has a relatively uniform visual response at different viewing angles even when the underlying conductive structures have a three-dimensional shape.

Abstract: An electronic device can detect whether the device is submerged in water using measurements from one or more electrodes. In some examples, the water detection can differentiate between a user contact with an electrode or the electrode submerged in water. In some examples, the detection of water can trigger water-related functions on device.

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.
