Abstract
A seating structure includes a base, a seat, a backrest connected to the seat, and an electronic circuit supported by the base. The seat or the backrest includes a carrier and a suspension material secured to the carrier and spanning across an opening formed by the carrier. The suspension material includes a plurality of electrostatic discharge fibers. The electronic circuit is coupled to the electrostatic discharge fibers. The electronic circuit includes an electronic processor and a sensor. The sensor is configured to generate an output signal indicative of an electrical parameter of one of the electrostatic discharge fibers. The electronic processor is configured to apply a drive signal to one of the plurality of electrostatic discharge fibers, receive the output signal from the sensor, and determine a state of the seating structure based on the output signal from the sensor.
