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 pressure sensor has a base layer, a supporting structure arranged on the base layer, and an elastic layer disposed above the base layer and the supporting structure. The elastic layer has a curved lower surface that is recessed away from the base layer. The curved lower surface, the supporting structure and the base layer define a cavity with an arched top wall. A first electrode, a second electrode, and an elastic body are all arranged within the cavity, such that when the elastic layer is elastically deformed in a direction of the base layer, the variable resistance elastic body electrically connects the first electrode with the second electrode, so as to generate a first signal related to the elastic deformation of the variable resistance elastic body.

Pressure sensor

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.
