首次提出并表征了一种新型的光电二极管嵌入纱线，为监测人体生命体征(包括心率、血氧和皮肤温度)和环境条件(光、湿度和紫外线)提供了新的可能性。为了创造一种与电子设备集成在一起的舒适、保形、美观和可洗的电子纺织品，电子元件最好以纱线的形式集成在纺织面料的结构中。该设备首先被封装在一个保护性的透明树脂微型吊舱中，然后被纤维护套覆盖。树脂微舱和覆盖纤维对器件的光活性区域接收的光的性质有显著影响。这项工作表征了将光电二极管封装在树脂微舱中和用纤维鞘覆盖微舱对光电参数的影响。提出了一个理论模型来提供对这些效应的估计，并使用两种光电二极管类型和一系列不同的树脂微胶囊进行了实验验证。这一知识可能会更广泛地应用于其他具有小规模光电子元件的设备。洗涤测试证实，纱线可以经受多次机洗和烘干循环，而不会降低性能。
A novel photodiode-embedded yarn has been presented and characterized for the first time, offering new possibilities for applications including monitoring body vital signs (including heart rate, blood oxygen and skin temperature) and environmental conditions (light, humidity and ultraviolet radiation). To create an E-Textile integrated with electronic devices that is comfortable, conformal, aesthetically pleasing and washable, electronic components are best integrated within the structure of a textile fabric in yarn form. The device is first encapsulated within a protective clear resin micro-pod before being covered in a fibrous sheath. The resin micro-pod and covering fibres have a significant effect on the nature of light received by the photoactive region of the device. This work characterised the effects of both encapsulating photodiodes within resin micro-pods and covering the micro-pod with a fibrous sheath on the opto-electronic parameters. A theoretical model is presented to provide an estimate for these effects and validated experimentally using two photodiode types and a range of different resin micro-pods. This knowledge may have wider applications to other devices with small-scale opto-electronic components. Wash tests confirmed that the yarns could survive multiple machine wash and drying cycles without deterioration in performance.
