An occupant information sensing device 100 includes a plurality of heater electrodes that are provided at a vehicle steering wheel 104 and insulated and separated from one another and that generate heat by conduction. Power sources provide electrical current for heater electrodes. Electrical circuit elements enable the system to provide occupant biological condition monitoring, gripping detection, and electrical stimulation. The circuits enable common electrical connecting to the heater electrodes to provide multiple functions through the use of filtering and time division multiplexing.
