An electric field sensor comprises at least one electrode mountable in a vehicle seat and a sensing circuit operatively coupled to the electrode, wherein the at least one electrode at least partially bounds at least one region that is proximate to an object such as an infant seat, a child seat, or a booster seat, for which the sensitivity of the sensor is preferably reduced. The at least one region without a conductive electrode may comprise a plurality of regions, and at least one of the regions may extend laterally across the seat. Furthermore, a plurality of electrodes may be incorporated, each having a different sensitivity to particular objects to be sensed, wherein an overall capacitance measurement that is dominated by the capacitance of the particular electrode that is most sensitive to the particular object can be used to indicate the presence of that object.

[ We claim:] [1.]1. A vehicle seat, comprising an electrode operatively coupled to said vehicle seat, wherein said electrode is formed with at least one slot or opening such that said electrode at least partially bounds at least one region within said at least one slot or opening that is located proximate to a portion of an occupant selected from an infant or child that is closest to said vehicle seat when the infant or child is seated in an infant seat, a child seat, or a booster seat, and the infant seat, the child seat or the booster seat is placed on said vehicle seat.
