1. An apparatus for applying an alternating electric field to a subject's body using a plurality of electrode elements, wherein each of the plurality of electrode elements is disposed in thermal contact with a respective thermistor, the apparatus comprising:
an AC signal generator that generates an AC output signal;
a connector that includes a plurality of pins, wherein each of the pins corresponds to a respective one of the plurality of electrode elements;
a first plurality of switches, wherein each of the first plurality of switches is configured to selectively either apply or not apply the AC output signal to a respective one of the pins;
an amplifier configured to accept an electrical signal from each of the thermistors and generate a corresponding output, wherein the electrical signals from the thermistors arrive via the same pins that correspond to the plurality of electrode elements; and
a controller configured to, based on the output of the amplifier, control the first plurality of switches so as to individually adjust the duty cycle of the AC signal that is applied to each of the plurality of pins.
