Abstract
A haptic keyboard of an information handling system may include a coversheet to identify a key location of the haptic keyboard; 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 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 an electric actuation signal from the piezoelectric element placed under the mechanical stress via the contact foil; and send an electrical response signal to the piezoelectric element to cause the piezoelectric element to generate haptic feedback at the key location.
