A case for an electronic device is disclosed. The case includes a body defining an interior volume configured to receive the electronic device therein. The body includes a user input region formed from a deformable material having an electrical resistance that decreases in response to a touch force on the deformable material, and an electrode pair in contact with the deformable material and configured to be operatively coupled to a sensing circuit configured to detect a change to the electrical resistance of the deformable material due to the touch force. The body also includes a connector configured to operatively couple the electrode pair to the electronic device.
