Abstract: A capacitive sensor electrode for sensing a touch input. A material is configured to temporarily modify a capacitance of the capacitive sensor electrode during a period after a touch input has occurred. After the touch input has occurred, a material change in capacitance of the material is relatively slower than an electrode change in capacitance of the capacitive sensor electrode.
