Abstract
Official abstract text for this publication.
A pressure-sensitive sensor includes a hollow tubular member including an elastic insulating material, and n electrode wires (n being an integer of not less than 3) arranged away from one another and held inside the tubular member. When an external pressure is applied to the tubular member, the tubular member elastically deforms such that at least two of the n electrode wires contact with each other. The n electrode wires extend linearly and parallel to a central axis of the tubular member.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a pressure-sensitive sensor, the sensor comprising a hollow tubular member comprising an elastic insulating material, and n electrode wires (n being an integer of not less than 3) arranged away from one another and held inside the tubular member, wherein when an external pressure is applied to the tubular member, the tubular member elastically deforms such that at least two of the n electrode wires contact with each other, the method comprising: forming the tubular member by extruding the elastic insulating material to be the tubular member around the n electrode wires while feeding the n electrode wires linearly and parallel to each other; and injecting a compressed gas inside the tubular member. 2. A method for manufacturing a pressure-sensitive sensor, the sensor comprising a hollow tubular member comprising an elastic insulating material, and n electrode wires (n being an integer of not less than 3) arranged away from one another and held inside the tubular member, wherein the electrode wires each comprise a metal wire and a conductive elastomer formed around the metal wire, and wherein when an external pressure is applied to the tubular member, the tubular member elastically deforms such that at least two of the n electrode wires contact with each other, the method comprising: forming the n electrode wires and the tubular member by co-extruding the conductive elastomer around each of the n metal wires and the elastic insulating material around the electrode wires while feeding the n metal wires linearly and parallel to each other; and injecting a compressed gas inside the tubular member.
