Abstract:
A coversheet layer of an information handling system, comprising a coversheet having a key location of a haptic keyboard and a haptic touchpad area on a C-cover for the information handling system including a magnet or ferromagnetic insert in the coversheet for alignment to a top replaceable overlay layer magnetically attachable to the coversheet, a support layer, a contact foil placed between the coversheet and support layer, a piezoelectric element placed between the contact foil and support layer to receive an applied mechanical stress at the key location or touchpad actuation location of the coversheet and generate an electric actuation signal and a controller of the information handling system operatively coupled to the contact foil to receive the electric actuation signal and send an electrical haptic response signal to the piezoelectric element to cause the piezoelectric element to generate haptic feedback.
