微型热电堆，可以通过使用现代薄膜和厚膜技术制造的讨论作为可穿戴设备的电源。在典型的人类及其生活环境的热特性的情况下，可以产生的最大功率的中小型热电堆进行了模拟。通过实验获得了模拟所需的人体局部热阻。讨论了可穿戴温差发电器的设计。在单位体积温差发电器产生的功率接近最大值的情况下，对微型热电堆可穿戴式温差能量采集器的总体设计进行了优化。所获得的性能特征允许预测人体热量的可穿戴能量采集器的应用领域及其市场成功的前景。
Miniature thermopiles that could be fabricated by using modern thin- and thick-film technologies are discussed as a power supply to wearable devices. The maximum power that can be produced by a thermopile of a medium-to-small size was simulated in case of typical thermal properties of humans and their living environment. The local thermal resistances of human being required for the simulation were obtained experimentally. The designs of wearable thermoelectric generators are discussed. The general design optimization of wearable thermoelectric energy harvester with a miniature thermopile was performed in case of near-maximum power generated per unit volume of thermoelectric generator. The obtained performance characteristics allow prediction of the application area for wearable energy harvesters of human body heat and the perspectives of their market success.
