可穿戴运动传感的准确性和稳定性研究

[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.

近年来，可穿戴传感器作为一种柔性便携的传感器件，可长期实时监测人体运动健康信息，进而为后续的临床诊断和治疗提供重要依据，受到广泛关注。不过，现有的可穿戴传感器在实际应用中，仍面临多方面的挑战，包括获取的传感数据如何精准映射肌体健康，如何降低传感器在工作过程中的漂移，从而提升监测的准确性和稳定性等。本报告将针对以上问题，以可穿戴运动传感为例，讲述利用多模态传感结合人工智能分析手段实现肌力等级的准确诊断，和基于摩擦电编码器实现离散化高稳定性的拉伸传感，助力可穿戴传感的实际应用。

面向数字健康的柔性电化学传感器件与集成系统

[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

传感与交互纤维电子器件

[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.

因可穿戴技术的发展，柔性电子材料与器件获得了大量关注，目前可穿戴领域的研究相继展示了“佩戴”形式的柔性器件，但多数仍缺乏柔韧性、或不可拉伸、难以编织，其主要作为服装的附加品，缺乏穿着舒适性。相比之下，纤维作为常用的服装材料是更合适的电学功能物理载体，有望成为更理想的可穿戴功能集成平台。鉴于此，我们认为纤维将成为新一代柔性器件形态，基于纤维电子与织物电子的智能服装产品在不久的将来会进入人们的生活。我们利用界面自组装、熔融纺丝和静电纺丝等连续化工艺制备了一系列新型纤维、织物电子材料与器件，特别是实现了多组分多界面电学纤维的万米级制备，解决了纤维状电子器件难以连续化大规模稳定制备的问题。进一步通过演示实验验证了这些新型电子器件在智能交互、环境特征因子检测与体征传感等领域的应用价值。
