Abstract: A pressure module comprises a substrate, a support structure and a pressing membrane. The support structure is connected to the substrate and the pressing membrane to form an accommodating cavity between the substrate and the pressing membrane. An electrode is disposed on a surface of the substrate or the pressing membrane and a variable resistance layer is respectively disposed on the opposite surface of the other of the substrate and the pressing membrane. On application of pressure to the pressing membrane, the pressing membrane is elastically deformed and the variable resistance layer is brought into contact with the electrode to form a contact area and a resistance value between the variable resistance layer and the electrode. The contact area and the elastic deformation is positively correlated.

Abstract: A button structure comprises a keycap, an elastic body, a scissor mechanism, and a piezoresistive film sensor arranged on a support plate. The scissor mechanism and the elastic body are arranged between the keycap and the piezoresistive film sensor. The piezoresistive film sensor comprises a first pressure sensing area and a second pressure sensing area. The elastic body corresponds to the first pressure sensing area and the scissor mechanism corresponds to the second pressure sensing area, such that, when a pressure is applied to the keycap, a first pressure acts on the elastic body to generate pressure on the first pressure sensing area and a second pressure acts on the scissor mechanism to generate pressure on the second pressure sensing area.

Abstract: A button structure has a base having a slot and a sensing element inserted into the slot. A pressure concentration element is fixedly connected by bonding to the sensing element and a key cap is mounted to the base. The key cap has a core member fixedly connected to a lower surface of a top plate of the key cap. The lower surface of the core member can be brought into contact with the pressure concentration element on application of a pressure to an upper surface of the top plate, such that the applied pressure is transmitted to the sensing element through the core member and the pressure concentration part. The sensing element is a piezoresistive film sensor.

Abstract: A key mechanism comprises an elastic structure comprising a first cavity located above a second cavity which are spaced apart from each other. The key mechanism comprises first and second button structures. The second button structure comprises an electrode layer on an upper wall of the second cavity and an electrode layer on a lower wall of the second cavity. The second button structure has an elastic body on the surface of one of the electrode layers. The first button structure is configured to generate a first key signal when a force is applied to an upper wall of the first cavity and compress the upper wall of the second cavity upon application of that force. The electrode layers come into contact to generate a second key signal in response to elastic deformation of the elastic body when the force is applied.

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.
