Dupont PE873

我司供應(yīng)智能穿戴，IME,柔性傳感器*可拉伸導(dǎo)電銀漿，壓力油墨，可拉伸絕緣油等材料。

可穿戴設(shè)備已成為每個(gè)人生活的一部分，并且越來(lái)越受歡迎。隨著從醫(yī)療保健到健身追蹤的多樣化應(yīng)用，越來(lái)越多的可穿戴設(shè)備正在開(kāi)發(fā)中，它們可以實(shí)時(shí)發(fā)送和接收信息。迄今為止，就可靠性和電阻而言，電纜代表了較穩(wěn)定的通信形式。然而，對(duì)于可穿戴系統(tǒng)，電纜會(huì)限制運(yùn)動(dòng)并在可穿戴傳感系統(tǒng)上引入額外的噪聲和運(yùn)動(dòng)偽影。另一方面，無(wú)線設(shè)備在設(shè)計(jì)、制造和使用方面可能相對(duì)復(fù)雜。為了改善可穿戴系統(tǒng)中的通信，一種可能的策略是采用能夠傳導(dǎo)電信號(hào)的導(dǎo)電墨水，這些墨水可以打印在織物上，而不會(huì)受到傳統(tǒng)有線系統(tǒng)通常相關(guān)的運(yùn)動(dòng)限制。因此，在可穿戴傳感器中使用這種導(dǎo)電墨水可能會(huì)帶來(lái)一種*舒適的全天監(jiān)測(cè)健康數(shù)據(jù)（心率、肌肉收縮等）的方法。本文對(duì)有前途的導(dǎo)電油墨PE873（杜邦公司生產(chǎn)）的性能進(jìn)行了測(cè)試和分析。研究了與拉伸、折疊和洗滌測(cè)試相關(guān)的導(dǎo)電油墨電性能。評(píng)估并展示了印刷在所選織物上的油墨的電氣性能。此外，還提出了一種旨在提高連接性能的優(yōu)化印刷程序，并展示了一種基于 PE873 能夠讀取肌肉收縮的新型系統(tǒng)的開(kāi)發(fā)，從而表明這種導(dǎo)電墨水是一種有前途的可拉伸電連接解決方案在可穿戴領(lǐng)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 signals, 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.
