Abstract: A unicouple based thermoelectric system comprises a thermoelectric circuit integrated into a cellular foam seat pad. The foam seat pad comprises an upper foam layer and a main foam layer. The thermoelectric circuit comprises a plurality of unicouples with heat sinks which may be pressed through insertion holes in the upper foam into airflow channels in the main foam. The upper foam seals the air channels from leakage which improves the airflow across the heat sinks. Further, the upper foam may be interlocked with the main foam. Alternatively, the upper foam may comprise the insertion holes and a portion of the airflow channels.
