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.
