智慧電子布料，將能更有效率偵測人體動作

下一代電子產品將在結合穿戴技術產品的出現下蓬勃發展。智能可穿戴裝置與人體結合，監測生理狀況或增強人體功能，成為未來社會最有潛力的技術之一。

人們日常生活中必不可少的紡織品布料，由於輕便、靈活、透氣和耐用的特點，已被人類使用了數千年。傳統紡織技術與電子工程技術（e-textile）的結合，市面上除了普遍使用織物作為​​服裝、覆蓋物或裝飾材料外，在電子、運動、醫學和人工智能等發展中的領域也有進行運用。

在中國科學院化學研究所的研究人員最近發表在“高級電子材料”上的一篇論文中，報告了用電子染色法對織物進行人體運動監測和分析的可伸縮傳感器。通過整合傳統的染色技術和電子工程，一種具有伸展性的導電織物，能夠了解在人體運動過程中承受的壓力，並通過電子信號輸出。

通過特定的銀導體和工藝優化，反應導體中的銀離子被原位還原成銀納米晶體並牢固地附著在織物的纖維表面上。均勻且緻密的銀粒子吸收和覆蓋在布料上，使布料具有導電性能。紡織物的伸展會導致電子電導率變化，並可以在記錄判讀儀器的幫助下輸出不同的信號。此外，研究人員還調整了紡織品的質地，以適應不同的伸縮壓力幅度，以滿足人體溫和或強勁的運動。因此，這種導電織物回饋出良好的柔韌性和適應性的應變 - 電子反應。

由於這種電子紡織品具有不錯的伸展性和耐久性，電子紡織品傳感器可以通過包覆在人體關節，從手指輕柔觸摸到劇烈的跑步，捕捉和監測各​​種人體活動。通過對輸出信號進行一定的統計分析，所連接的傳感器陣列不僅可以監測步行、慢跑、下蹲、跳躍、伸展等動作，還可以有效進行生物監測。甚至未來ㄐㄧ機器人。

Wearable Electronic Fabric Sheds Light On Human Motion Monitor

The next-generation electronics thrive on the emergence of wearable technologies. Smart wearable devices that could be integrated with the human body to monitor the physiological activity or enhance the function of the human body have emerged as one of the technologies with the most potential in the future society.

Textiles which are indispensable in our daily life have been used for thousands of years due to their lightweight, flexible, permeability and durable features. Beyond the common use of fabric as clothes, covering or decoration materials, the integration of traditional textile technology and burgeoning electrical engineering, known as e-textile, has been rapidly exploited in evolving fields of electronics, sports, medical science and artificial intelligence.

In a recent paper published in Advanced Electronic Materials, researchers from the Institute of Chemistry, Chinese Academy of Sciences, reported the textile-based stretchable sensor by electronic dyeing method for human motion monitoring and analysis. By integrating the traditional dyeing technology and electronic engineering, a stretchable conductive fabric that could in real time response to the different stress of human body during the motion with an electronic signal output.

With specific silver precursor selection and process optimization, the silver ion in the reactive precursor was in-site reduced into silver nanocrystals and firmly attached on the fiber surface of the textiles. The uniform and dense silver absorption and coverage contribute the conductive performance of the textiles. The stretch of the textiles will bring about the electronic conductivity change and could output different signals with the help of the recorder. Moreover, the authors regulated the texture of the textile to match with the different amplitude of stress for satisfying the various gentle and vigorous motions of the human body. Thus, the conductive textiles show good flexibility and adaptable strain-electric response.

Owing to the commendable mechanical performance and high durability of the textile matrix, the electronic textile sensor could capture and monitor various human activities by attaching on the motion of joints in the human body, from the gentle finger touch to the vigorous running. With certain statistical analysis of the output signal, the attached sensor array could not only monitor simple motions, such as walk, jog, squat, jump and extend, but also could effectively distinguish the similar motions, which have great potential in biomonitoring, soft co-robotics, and human-machine interaction.

The work is led by Prof. Yanlin Song and finished by his graduate students Yudong Li, Yanan Li, and Dr. Fengyu Li at the Institute of Chemistry Chinese Academy of Sciences. The study, Electronic Textile by Dyeing Method for Multiresolution Physical Kineses Monitoring was recently published in the journal Advanced Electronic Materials.
