  • Publication number: 20250180415
    Abstract: 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, having a curved lower surface that is recessed away from the base layer. The curved lower surface, supporting structure and base layer define a cavity with an arched top wall. A first electrode and a second electrode are arranged on the lower surface of the elastic layer, the second electrode spaced apart from the first electrode, and a variable resistance elastic body is arranged on the base layer, opposite to the first and second electrodes; all arranged within the cavity. When the elastic layer is elastically deformed in a direction of the base layer, the 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 elastic body.

  • Publication number: 20240013990
    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.

  • Patent number: 11868554
    Abstract: 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.

  • Publication number: 20230064769
    Abstract: A pressure sensor comprises a substrate and a conductive layer disposed on the substrate and a spacer layer having a thickness larger than the thickness of the conductive layer. The pressure sensor also comprises an elastic membrane connected to the spacer layer, which overlays the conductive layer with the spacer layer providing a space therebetween and a sensing electrode layer arranged on a lower surface of the elastic membrane and spaced apart from the conductive layer. The sensing electrode layer forms at least two electrodes opposed and spaced apart from each other. The two electrodes are respectively connected to respective connectors and contact the conductive layer in response to an applied pressure on the elastic membrane. Each electrode transmits an output signal of resistance data to a processor through the respective connector.
