A sensor, ideally for a car seat, is disclosed in which an electro-conductive textile (ECT) is used to simultaneously deliver energy to the occupant to the seat in the form of heat, and to sense the nature or characteristics of the occupant of that seat. To achieve these functions, the ECT is connected to both a control circuit and a charge transfer/capacitance measuring circuit. The control circuit ensures that the ECT does not become too hot during use, and the charge transfer/capacitance measuring circuit is capable of determining not only if the seat is occupied but also the nature of the occupant, in particular the size and/or weight.
