Textile-based thermoelectric (TE) devices are being investigated to power smart textiles autonomously. While previous research has focused on a solid system where the required junctions are fabricated into the device, there has been limited attention given to replacing these TE systems reliably. This work looks at a newer approach to the construction and demonstration of a wearable thermoelectric structure that employs three-dimensional knitted spacers to increase the temperature difference where the TE junctions are detachable and disposable. This system features positive and negative junctions which can be removed while maintaining its excellent voltage generation in low ΔT and good Seebeck coefficients. A mathematical model simulates the potential energy outputs and maximum power points generated, which can be used to increase the device's performance for future wearable sensing applications.
基于纺织品的热电（TE）装置正在被研究，以便为智能纺织品自主供电。虽然先前的研究集中在一个固体系统，其中所需的结被制造在装置中，但对于可靠地替换这些TE系统的关注有限。这项工作着眼于一种构建和演示可穿戴热电结构的新方法，该结构采用三维针织间隔物来增加热电结可拆卸和一次性使用时的温差。该系统具有正结和负结，在保持其在低温差下出色的电压产生和良好的塞贝克系数的同时，可以将这些结移除。一个数学模型模拟了产生的势能输出和最大功率点，可用于提高该装置在未来可穿戴传感应用中的性能。
