ABSTRACT:
The invention relates to a sensor arrangement for seat occupation detection, comprising a fiber-optic sensor network consisting of at least two sensors. The sensor network detest for example local damping modifications in a fiber network that are caused by microbends or modifications of the Bragg wavelength of fiber-optic Bragg grating sensors (FBGS) distributed in the fiber network that are ceased by loads. The optical sensor network is resistant to electromagnetic parasitic inductions. Due to the nature of the optical lass or polymer optical fibers it is for example possible to integrate the network into the textile cover of the seat or into a cushion.
