    • A physical force capacitive touch sensor comprises a capacitive sensor element on a substrate, a physically deformable electrically insulating spacer over the capacitive sensor element, and a conductive plane over the physically deformable electrically insulating spacer that is substantially parallel to the capacitive sensor element. The conductive plane is connected to a power supply common and/or grounded to form a capacitor with the capacitive sensor element and for improved shielding of the capacitive sensor element from electrostatic disturbances and false triggering thereof. A protective cover may be placed over the conductive plane to act as an environmental seal for improved physical and weather protection, but is not essential to operation of the capacitive touch sensor.
    • 物理力电容式触摸传感器包括基板上的电容式传感器元件,电容式传感器元件上的可物理变形的电绝缘隔离物,以及基本上平行于电容式传感器元件的物理上可变形的电绝缘间隔物上的导电平面。 导电平面连接到公共和/或接地的电源以与电容式传感器元件形成电容器,并且用于改善电容式传感器元件的屏蔽以免静电干扰和其错误触发。 保护盖可以放置在导电平面上以用作环境密封件,以改善物理和天气保护,但对于电容式触摸传感器的操作来说不是必需的。
