Abstract
A fascia panel assembly includes an electrically non-conductive fascia panel, an electrically non-conductive isolator, and a capacitance sensor. The sensor capacitively couples to an electrically conductive object proximal to the sensor while the sensor is driven with an electrical charge such that capacitance of the sensor changes due to the sensor capacitively coupling with the object. The isolator is sandwiched between the fascia panel and the isolator.
