Abstract
A method is provided for fabricating a bending beam sensor coupled to a touch input device. The method includes providing a bending beam. The method also includes placing a first strain gauge and a second strain gauge on a surface of the beam near a first end of the beam, and aligning the first strain gauge and the second strain gauge with the beam along an axis. The first end is attached to a base. The method further includes coupling the first strain gauge and the second strain gauge to a plate of the touch input device and electrically connecting the first strain gauge and the second strain gauge such that a differential signal is obtained from the first strain gauge and the second strain gauge when a load is applied on the plate of the touch input device.
