Fascia panel assembly having capacitance sensor operative for detecting objects

摘要

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.

1. An assembly comprising:
an electrically non-conductive isolator mountable to a flexible fascia panel; and a capacitance sensor attached to the isolator, wherein 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; wherein the isolator is flexible such that in response to the fascia panel displacing upon an object touching the fascia panel the isolator also displaces to thereby cause the sensor to displace, wherein the capacitance of the sensor changes due to the displacement of the sensor.
