可穿戴设备已成为每个人生活的一部分，并且越来越受欢迎。随着从医疗保健到健身追踪的多样化应用，越来越多的可穿戴设备正在开发中，它们可以实时发送和接收信息。迄今为止，就可靠性和电阻而言，电缆代表了较稳定的通信形式。然而，对于可穿戴系统，电缆会限制运动并在可穿戴传感系统上引入额外的噪声和运动伪影。另一方面，无线设备在设计、制造和使用方面可能相对复杂。为了改善可穿戴系统中的通信，一种可能的策略是采用能够传导电信号的导电墨水，这些墨水可以打印在织物上，而不会受到传统有线系统通常相关的运动限制。因此，在可穿戴传感器中使用这种导电墨水可能会带来一种更舒适的全天监测健康数据（心率、肌肉收缩等）的方法。本文对有前途的导电油墨PE873（杜邦公司生产）的性能进行了测试和分析。研究了与拉伸、折叠和洗涤测试相关的导电油墨电性能。评估并展示了印刷在所选织物上的油墨的电气性能。此外，还提出了一种旨在提高连接性能的优化印刷程序，并展示了一种基于 PE873 能够读取肌肉收缩的新型系统的开发，从而表明这种导电墨水是一种有前途的可拉伸电连接解决方案在可穿戴领域。

Nowadays, wearable devices are part of everyone’s life and their popularity is constantly increasing.

With diverse applications, spanning from healthcare to fitness tracking, more and more

wearable devices are being developed which can send and receive information in real-time.

To date, electric cables represent the most stable form of communication in terms of reliability

and resistance. However, for wearable systems, cables restrict movement and introduce

additional noise and movement artefacts on wearable sensing systems. Wireless devices,

on the other hand, can be comparatively complicated in design, manufacturing and use.

A possible strategy, to improve communications in wearable systems, is the adoption

of conductive inks able to conduct electrical **s, these can be printed on fabric

without the movement restriction normally associated with traditional wired systems.

The use of such conductive inks in wearable sensors may, therefore, lead to a more comfortable method

of monitoring health data (heart rate, muscle contraction etc.) throughout the day.

In this paper, the properties of the promising conductive ink PE873 (manufactured by DuPont)

are tested and analysed. The conductive ink electrical properties are studied in relation to stretching,

folding and washing tests. The electrical performance of the ink printed onto the selected fabric is assessed

and presented. Furthermore, an optimized printing procedure, aiming at improving the connection performances,

is suggested and the development of a novel system able to read muscle contractions, based on PE873, is demonstrated,

thus showing that this conductive ink is a promising solution for stretchable electrical connections in the wearable field.
