Abstract
A seat sensor includes a top sheet made of insulating film; an upper insulating layer with insulating particles partially protruding from the surface of the upper insulating layer; and an upper resistor layer formed over the upper insulating layer. The seat sensor further includes a bottom sheet made of insulating resin film disposed under the top sheet; a lower insulating layer with insulating particles partially protruding from the surface of the lower insulating layer; a lower resistor layer formed over the lower insulating layer, and an insulating spacer layer formed between the top sheet and the bottom sheet. The above construction provides a seat sensor that has stable resistance properties even after repeated loading and a detection device using the seat sensor.
