A button structure comprises a base layer, a supporting structure arranged on the base layer, an elastic film layer, the elastic film layer covering the support structure and connected to the support structure, the support structure and the elastic film layer defining a cavity above the base layer, a first upper electrode arranged on the lower surface of the elastic film layer and located in the cavity, a first lower electrode, arranged on the base layer and located in the cavity, and a first variable resistance elastic body between the first upper and first lower electrodes, either arranged on the lower surface of the first upper electrode or arranged on the upper surface of the first lower electrode. When the elastic film layer is elastically deformed in the direction of the base layer, the first variable resistance elastic body connects the first upper electrode with the first lower electrode so as to generate a first signal related to the elastic deformation of the first variable resistance elastic body.

Button structure

A touch device comprises a base, a membrane pressure sensor arranged on the base, a touch sensing layer covering the membrane pressure sensor, and a force feedback structure arranged on the lower surface of the touch sensing layer and electrically connected to the membrane pressure sensor. The membrane pressure sensor is configured to generate a pressing signal related to the force applied to it, and the force feedback structure is configured to receive the pressing signal and generate a feedback force corresponding to it.

Touch device

An apparatus for use in the assembly of an electronic device, such as a mobile telephone, comprises a pressure sensor. The pressure sensor is embedded within an inner elastic layer and the inner elastic layer is embedded within an outer elastic layer. The inner elastic layer has an elastic modulus which is greater than the elastic modulus of the outer elastic layer.

Electronic device comprising a pressure sensor

A pressure sensor comprises a first sensing module comprising a first negative electrode and first support structures arranged at intervals on the first negative electrode. A first flexible insulating layer covers an upper surface of the first support structures and first positive electrodes are arranged at intervals on a lower surface of the first flexible insulating layer and distributed between the first support structures. A second sensing module comprises a second negative electrode disposed on the first flexible insulating layer and second support structures are arranged at intervals on the second negative electrode. A second flexible insulating layer covers an upper surface of the second support structures. Second positive electrodes are arranged on a lower surface of the second flexible insulating layer at intervals and distributed between the second support structures. The first support structures are offset from the second support structures.
