可穿戴運動傳感的準確性和穩定性研究

[ABSTRACT]

In recent years, wearable sensors, as a type of flexible and portable sensing device, have been able to monitor human motion and health information in real time for extended periods, thus providing important data for subsequent clinical diagnosis and treatment, which has attracted widespread attention. However, existing wearable sensors still face multiple challenges in practical applications, including how to accurately map the sensed data to physical health, how to reduce sensor drift during operation, thereby enhancing the accuracy and stability of monitoring, etc. This report will address the above issues, taking wearable motion sensing as an example, to discuss the use of multimodal sensing combined with artificial intelligence analysis methods to achieve accurate diagnosis of muscle strength levels, and the realization of discrete, high-stability stretching sensing based on triboelectric encoders, to aid the practical application of wearable sensing.

近年來，可穿戴傳感器作為一種柔性便攜的傳感器件，可長期實時監測人體運動健康信息，進而為后續的臨床診斷和治療提供重要依據，受到廣泛關注。不過，現有的可穿戴傳感器在實際應用中，仍面臨多方面的挑戰，包括獲取的傳感數據如何精準映射肌體健康，如何降低傳感器在工作過程中的漂移，從而提升監測的準確性和穩定性等。本報告將針對以上問題，以可穿戴運動傳感為例，講述利用多模態傳感結合人工智能分析手段實現肌力等級的準確診斷，和基于摩擦電編碼器實現離散化高穩定性的拉伸傳感，助力可穿戴傳感的實際應用。

面向數字健康的柔性電化學傳感器件與集成系統

[ABSTRACT]

To realize comprehensive and reliable health monitoring, real-time physiological monitoring technology in molecular level is urgently demanded. Current biosensing technology encounters the challenges of simultaneously enhancement on sensitivity and stability, as well as system integration without external connections. Our research focused on high performance electrochemical devices, flexible biosensors and monolithically integrated systems for wearable and digitalized healthcare applications. To realize controllable construction of highly sensitive and stable biosensors, the design of conformal and interpenetrating interfaces was proposed to realize continuous and stable monitoring of biomarkers at micro-molar levels. Moreover, to tackle the challenge of monolithic integration of multi-functional devices, highly precise and controllable strategies for functional materials deposition and compatible device integration were developed towards wearable and non-invasive physiological applications. These research aims at advancing the wearable biosensing technology towards proactive healthcare

傳感與交互纖維電子器件

[ABSTRACT]

Flexible electronic materials and devices has attracted considerable interest. The current research in the field of wearable technology has demonstrated the feasibility of creating flexible devices in a wearable form. However, the majority of these devices lack flexibility or are not stretchable, making them difficult to weave. They are primarily used as an add-on to garments and lack the wearing comfort of traditional clothing. In contrast, fibres, which are commonly used in the manufacture of clothing, are more suitable physical carriers of electrical functionality. It seems reasonable to posit that fibres will emerge as a novel generation of flexible electronic devices, with smart clothing products based on fiber-electronics becoming a common feature of peoples lives in the near future. A series of fiber-electronic materials and devices have been prepared using continuous processes. Notably, the challenge of preparing fiber-electronics on a large scale in a continuous manner has been addressed. The potential applications of these electronic devices in intelligent interaction, environment and body sensing are further validated.

因可穿戴技術的發展，柔性電子材料與器件獲得了大量關注，目前可穿戴領域的研究相繼展示了“佩戴”形式的柔性器件，但多數仍缺乏柔韌性、或不可拉伸、難以編織，其主要作為服裝的附加品，缺乏穿著舒適性。相比之下，纖維作為常用的服裝材料是更合適的電學功能物理載體，有望成為更理想的可穿戴功能集成平臺。鑒于此，我們認為纖維將成為新一代柔性器件形態，基于纖維電子與織物電子的智能服裝產品在不久的將來會進入人們的生活。我們利用界面自組裝、熔融紡絲和靜電紡絲等連續化工藝制備了一系列新型纖維、織物電子材料與器件，特別是實現了多組分多界面電學纖維的萬米級制備，解決了纖維狀電子器件難以連續化大規模穩定制備的問題。進一步通過演示實驗驗證了這些新型電子器件在智能交互、環境特征因子檢測與體征傳感等領域的應用價值。
