摘要： A pressure sensor comprises a base layer, a supporting structure arranged on the base layer, 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, wherein 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 the 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.

摘要： A pressure sensor (101) comprises a substrate (102) and a conductive layer (103) disposed on the substrate and a spacer layer (104) having a thickness (109) larger than the thickness (110) of the conductive layer. The pressure sensor also comprises an elastic membrane (106) connected to the spacer layer, which overlays the conductive layer with the spacer layer providing a space (113) therebetween and a sensing electrode layer (105) arranged on a lower surface (114) 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.

摘要： A pressure sensing device comprises a first diaphragm (104) which is deformable and a second diaphragm which is non-deformable (105). One of the diaphragms comprises a pressure sensitive material (115) arranged on its surface. The other diaphragm comprises a detection electrode (114) arranged its surface. The first diaphragm forms part of a force transmission device (103) comprising a cavity (106) having a force transmission fluid therein. The force transmission device is configured to receive an external force and transmit the external force to the first diaphragm, such that the first and second diaphragms are mutually deformed in response to the external force.

摘要： A key mechanism (201) comprises an elastic structure (202) comprising a first cavity (203) located above a second cavity (204) which are spaced apart from each other. The key mechanism comprises first and second button structures (205, 210). The second button structure comprises an electrode layer (211) on an upper wall (214) of the second cavity and an electrode layer (212) on a lower wall (215) of the second cavity. The second button structure has an elastic body (213) 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.
