A thermoelectric heat exchange module (202) includes a first substrate (404) including a heat receptive side and a heat donative side and a series of undulatory pleats. The module may also include a thermoelectric material layer (408) having a ZT value of 1.0 or more disposed on at least one of the heat receptive side and the heat donative side, and an electrical contact (502) may be in electrical communication with the thermoelectric material layer (408).
