Beschreibung
Zusammenfassung:	A device configured to determine the location and magnitude of a touch on a surface of the device. The device includes a transparent touch sensor that is configured to detect a location of a touch on the transparent touch sensor. The device also includes a force-sensing structure disposed at the periphery of the transparent touch sensor. The force sensor includes an upper capacitive plate and a compressible element disposed on one side of the upper capacitive plate. The force sensor also includes a lower capacitive plate disposed on a side of the compressible element that is opposite the upper capacitive plate.
