Abstract
A backlit haptic keyboard of an information handling system may comprise a contact foil placed between a coversheet and a support layer, operatively coupling an LED controller to an LED via metallic traces printed upon a top surface of the contact foil and operatively coupling a piezoelectric element to a keyboard controller via metallic traces printed upon a bottom surface of the contact foil. The system may further comprise the LED placed between the coversheet and the contact foil, and a piezoelectric element placed between the contact foil and support layer to receive an applied mechanical stress at a key and generate an electric actuation signal. A keyboard controller of the information handling system may receive an electric actuation signal from the piezoelectric element via the bottom metallic traces and send an electrical haptic response control signal to the piezoelectric element to cause it to generate haptic feedback at the key.
