Abstract: A force sensing device comprises a first electrode and a second electrode and a substrate comprising at least one groove. The force sensing device further comprises an active material between the first and second electrodes. The at least one groove comprises a first face and a second face inclined to the first face. The first face and second face are arranged a distance apart from each other. The first electrode is deposited on the first face and the second electrode is deposited on the second face. The distance changes on application of an applied force to deform the active material and provide a change in an electrical property, such as resistance, capacitance or a combination, of the active material.

Abstract: An apparatus (201) for use in a display device comprises a light-emitting layer (203) for providing a light output to the display device and a translucent layer (202) comprising a pressure-sensitive ink. The translucent layer diffuses the light output from the light-emitting layer and the pressure-sensitive ink provides a conductive layer of a sensing device (205) which is configured to measure a force in response to a mechanical interaction.

Abstract: A foldable electronic device (101) includes a display device (102) moveable from an unfolded configuration to a folded configuration in which the display device folds along a fold axis (103). The electronic foldable device further includes a force sensing device (603) responsive to a manual interaction on the surface of the display device. The force sensing device is positioned on the fold axis of the display device.
