Opaque QTC® force touch sensors from Peratech (Richmond, North Yorks, England) can be integrated under a range of top surfaces such as plastics, rubbers, wood, leather, metals, and glass. The “3D multi-touch” matrix sensors provide a human-machine interface (HMI) experience in automotive cockpits. The sensors track multiple touches for position (X, Y) and independent pressure (Z) readings for each touch simultaneously. Introduction of z-axis pressure intelligence enables designers to reduce “button count” and complication from the center stack, steering wheel, and other cockpit surfaces. The sensors have been tested through cycles of -40 to +100 °C.
