Abstract
A haptic touchpad may include a seamless layer of glass; a touchpad assembly, including: a capacitive touch printed circuit board (PCB) operatively coupled to a bottom side of the seamless layer of glass via a first adhesive; a contact foil operatively coupled to the bottom surface of the capacitive touch PCB via a second adhesive; a piezoelectric element array operatively coupled to a bottom side of the contact foil to receive an applied mechanical stress; and a controller of the information handling system operatively coupled to the piezoelectric element array to: receive electric actuation signals from the piezoelectric element array placed under the mechanical stress via the contact foil; and send an electrical response signal to the piezoelectric element array to cause the piezoelectric element array to generate haptic feedback; and a unibody C-cover support frame to support the touchpad assembly and the seamless layer of glass.
