脉搏率（PR）是一个重要的生理参数，可以提供体力消耗的指示。因此，近年来，用于健身追踪的光脉冲率监测器越来越受欢迎，并已成为许多活动追踪器和智能手表的重要组成部分。这些设备通常使用光电体积脉搏图（PPG）来测量脉冲速率，这需要一个发光二极管（LED）和一个光电二极管的排列。LED将发光到皮肤上，根据血容量，一部分光谱将被吸收，通过光电二极管测量透射或反射光。通过记录血容量的变化，可以确定PR。这项工作提出了一种PR监测手套，其中红外LED和PPG所需的光电二极管已被离散地集成到纺织品的结构中。这是通过使用电子纱线（E-yarn）技术实现的，在这种技术中，小的电子芯片被焊接到细电线上，封装在树脂圆柱体中，并用纤维覆盖，从而制造出一种机械和化学上都很坚固的纱线，看起来和摸起来都像普通的纺织品。纱线的生产过程，以及纱线与纺织品的整合，将影响光学元件发出/收集的光，这些影响需要完全量化和理解，以便设计出最佳的传感设备。在早期研究的基础上，这项工作调查了重要的设计考虑因素，如LED嵌入式眼罩的发射模式，以创建一个PR监测手套。
Pulse rate (PR) is an important physiological parameter and can offer an indication of physical exertion. As such, optical pulse rate monitors for fitness tracking have grown in popularity in recent years and have featured as a component of many activity trackers and smart watches. These devices typically measure pulse rate using photoplethysmography (PPG) which requires an arrangement of a light emitting diode (LED) and a photodiode. The LED will emit light onto the skin and a portion of the light spectrum will be absorbed depending on the blood volume, with the transmitted or reflected light being measured by the photodiode. By recording the changes in the blood volume PR can be determined. This work presents a PR monitoring glove where an IR LED and a photodiode necessary for PPG have been discretely integrated into the structure of a textile. This has been achieved by using electronic yarn (E-yarn) technology where small electronic chips are soldered onto fine wires, encapsulated within a resin cylinder, and covered in fibers to create a mechanically and chemically robust yarn that looks and feels like a normal textile. The yarn production process, and the integration of the yarns into a textile, will affect the light emitted/collected by the optical components and these affects need to be fully quantified and understood so that an optimal sensing device can be engineered. Building on earlier studies this work investigates important design consideration, such as the emission pattern of the LED embedded Eyarns, in order to create a PR monitoring glove.
