Fig. 5: IC-LIG-Wood touch button panel.

Capacitive IC-LIG-wood touch button panel made with a thin wild cherry wood veneer. Image sequence showing that the initially “off” (a) LED lights can be switched “on” (b, c) by touching the front native wood veneer surface and moving the finger in the direction indicated by the black arrow. Pictures showing (d) the open device, (e) the rear wood veneer surface with the conductive IC-LIG touch buttons. f Demonstration of how thin the engraved veneer is (maximum thickness 450 µm).
