製造工程が多く、製造コストが高いという問題がある。The electrode material made of a metal plate has high rigidity against bending and excellent durability against external force, but is extremely hard and heavy, so that it is uncomfortable to use when installed near a human body. Will be given. For that reason,
The metal plate must be installed at a position away from the seat surface, and as a result, the detection accuracy may be deteriorated. Also, a metal-coated cloth-type conductive material obtained by plating a woven cloth is cut into a predetermined shape and bonded to a cloth base material, and is buried as an electrode material, for example, near the surface of an automobile seat, or as a seat surface. It has also been used to be sewn or adhered to fabric, but when a metal-coated fabric type conductive material is adhered to a substrate, the hardness is improved as compared to a metal plate electrode. However, it is still not enough, and as a result, the seating feeling of the seat is not good. In addition, when a metal-coated fabric type conductive material is sewn to a substrate, the feeling of sitting is somewhat improved as compared with bonding, but the kneading resistance is insufficient. Furthermore, in order to use the material that is plated on the fabric attached to the base material and incorporated into the seat structural material,
There is a problem that there are many manufacturing steps and the manufacturing cost is high.
