<p>PROBLEM TO BE SOLVED: To provide a seating sensor for grasping weight and a posture of a seated person with less influence due to environmental temperature fluctuation on reproducibility. SOLUTION: In a seating sensor mounted to a seat, a variable electrostatic capacity unit C1 is constructed of two electrodes D1, D2 differentiated from each other in potential. When electrostatic capacity of the variable electrostatic capacity unit C1 fluctuating by influence from a human body seated on the seat is converted into an electric signal, it is detected that the person is seated on the seat. The electrodes are printed on a resin film and covered with a protective film.</p> |
