在此，我们展示了通过采用棉线作为聚（3-己基噻吩）（P3HT）和银（Ag）浆料的平台，通过可选择的涂覆方法来制造柔性热电（TE）发电机的概念。涂层热电棉线可以缝制在具有不同编织图案的柔性织物上，形成热电装置。最重要的是，该装置的温度梯度是在柔性织物的横截面方向上，即衣服的内表面和外表面之间，因此由于人体与周围环境之间的温度梯度是在横截面方向上，因此该柔性装置可以很容易地穿戴在身上。当负载电阻与模块电阻匹配时，13个P-N型桥臂器件在50 K温度梯度下的最大输出功率达到1.15 μW。涂有 P3HT 的棉基 TE 设备可能有助于开发自供电可穿戴电子产品。
Herein, we demonstrate a concept of making flexible thermoelectric (TE) generators by applying cotton thread as the platforms for poly(3-hexylthiophene) (P3HT) and Argentum (Ag) paste through selectable coating method. The coated thermoelectric cotton thread can be sewed on the flexible fabrics with different knitting pictures and form thermoelectric devices. The most important is that the temperature gradient of the device was in the direction of cross-plane of the flexible fabrics, that is, between the inner and outer surfaces of clothing, therefore the flexible device can be easily wore on the body since the temperature gradient between the human body and surrounding environment is in the cross- plane direction. The maximum output power of the device with thirteen P-N type legs reached 1.15 mu W at a temperature gradient of 50 K when the load resistance matched the resistance of the module. Cotton-based TE device coated with P3HT may be useful for the development of self-powered wearable electronics.
