Abstract
Disclosed are electronic devices for detecting contact or close proximity to an object to be detected. An electronic device includes a capacitive sensor enclosed by a housing and a controller coupled to the capacitive sensor, where the controller is configured to detect contact or close proximity to an object to be detected, and where the capacitive sensor includes a capacitor with a sensor electrode. The sensor electrode is separated from an outer surface of the housing by the housing. At least a portion of the housing includes a partially conductive material and the sensor electrode is in conductive contact with the partially conductive material, or the sensor electrode is in conductive contact with an electrically conductive element on an inner surface of the housing or at least partially embedded in the housing.
