Abstract
A load detection sensor unit for a bedding comprises a plurality of load detection devices and a signal processing circuit which is connectable to an external electrical unit. The signal processing circuit includes a plurality of analog switches connected to the load detection devices, a single output line connected to the analog switches, and a load resistor connected to the single output lines. The analog switches are turned on sequentially so that output signals of the load detection devices are serialized and transmitted to the external electrical unit through the single output line. The load detection devices and the signal processing circuit are formed integrally on an elastic film and connected through elastic conductors.
