Abstract
A pressure sensor includes a substrate, a patterned circuit, and a conductive material layer. The patterned circuit, formed on the substrate, includes a first-path part and a second-path part of which at least a part is formed at a predetermined gap from at least a part of the first-path part. The conductive material layer, resiliently disposed on the patterned circuit, has protrusions. The conductive material layer deforms to determine a contact area between the protrusions and the substrate, and upon deformation of the conductive material layer to contact the first-path part, the gap between the first-path part and the second-path part, and the second-path part, the first-path part electrically connects to the second-path part.
Claims15
A pressure sensor, comprising:
- a substrate;
- a patterned circuit, formed on the substrate, and comprising a first-path part and a second-path part, wherein at least a part of the second-path part is formed at a predetermined gap from at least a part of the first-path part;
- and
- a conductive material layer, resiliently disposed on the patterned circuit, and having protrusions that protrude downward from the conductive material layer, extend in a longitudinal direction of the substrate, and are arranged in a width direction of the substrate,
- wherein the conductive material layer is elastically deformed by a pressure to determine a contact area between the protrusions and the substrate, and when the conductive material layer is elastically deformed by the pressure to contact the first-path part, the gap between the first-path part and the second-path part, and the second-path part, the first-path part is electrically connected to the second-path part by the conductive material layer,
- wherein each of the first-path part and the second-path part includes at least one of a first-line part extended in the longitudinal direction and a second-line part extended obliquely to the longitudinal direction, and one side portion of each of the first-path part and the second-path part includes the first-line part, and the other side portion of each of the first-path part and the second-path part includes at least one of the first-line part and the second-line part, and
- wherein when the first-path part and the second-path part are electrically connected to each other by the conductive material layer, the conductive material layer is in contact with at least a part of the other side portion of the first-path part and at least a part of the other side portion of the second-path part.
