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.

User-input systems and methods of detecting a user input at a cover member of a user-input system

A solid-state switch for an external system includes a cover member, a first solid-state transducer, a second transducer, a microcontroller, a user feedback device, and a switching circuit. The first transducer is mechanically coupled to the cover member and configured to generate first signals in response to a perturbation at the cover member. The second transducer is configured to generate second signals in response to the perturbation. The microcontroller is configured to obtain first data from the first signals, second data from the second signals, and determine user inputs in accordance with at least the first data, the second data, and an operational state of the solid-state switch. The user feedback device is configured to provide feedback to a user of the switch in accordance with a switching behavior of the switching circuit.
