Abstract: An illuminator may be coupled to the key cap of a key. The key cap may include a portion that is operable to be illuminated and one or more illuminators may be coupled thereto. In particular embodiments, keys may include power delivery systems that are operable to wirelessly transmit power from a power source to illuminators. Such power delivery systems can include inductive transmitters and/or receivers, ultrasonic transmitters and/or receivers, laser diodes and photodiodes, electrodes that capacitively couple to wirelessly transfer power, and so on. In various embodiments, keys may include interconnects that connect an illuminator with a power source. The interconnect may be a flexible material that includes one or more traces and is configured with a shape that bends and twists to allow movement without stretching. The interconnect may also be part of a movement or support mechanism of a key.
