Abstract
A user-input system includes a force-measuring device, a cover member, and an elastic circuit board substrate interposed between the force-measuring device and the cover member and mechanically coupled to the cover member and to the force-measuring device. The force-measuring device includes a strain-sensing element. The force-measuring device is mounted to and electrically connected to the elastic circuit board substrate. The cover member undergoes a primary mechanical deformation in response to forces imparted at the cover member. The elastic circuit board substrate transmits a portion of the primary mechanical deformation to the force-measuring device resulting in a concurrent secondary mechanical deformation of the force-measuring device. The strain-sensing element is configured to output voltage signals in accordance with a time-varying strain at the strain-sensing element resulting from the secondary mechanical deformation.
