（只有英文版本）Developing conductive underwater glue for fast sealing and in situ monitoring is critical for ocean exploration yet remains a challenge. The fluidity of glue is a double-edged sword that is favorable for molecule spreading and formation of interlocking bonding network yet also leads to leakage of conductive ions. Dr Jimin FU, member of RI-IWEAR, and collaborators (Si Yu Zheng, Jintao Yang, and etc.) design a polymeric glue based on triazole-beared macromolecules and ionic liquids, which is possessing good conductivity and exhibiting rapid, strong, and long-lasting underwater adhesion on diverse substrates at various harsh environments and extreme temperatures. Furthermore, the glue possesses additional functions of underwater sensing and fluorescent labeling, which exhibits great potentials in underwater repair and follow-up crack monitoring. In molecular design, the nitrogen heterocyclic motif that prevails in biomolecular recognition is encoded with water-resistant benzene block in one pendant group to serve as underwater binding sites; ionic liquids (ILs) of [EMIM][BF4] is employed as the solvent for fast water exchange that triggers rapid adhesion. Simultaneously, the polymer-IL interaction is regulated, with the assistance of the theoretical calculations, to retain sufficient ILs within the adhesive for sensing. Finally, the glue is applied for underwater sealing and in situ monitoring various physical signals, while the fluorescent property is utilized for underwater labeling. This study should provide a new design strategy for the next-generation of multifunctional underwater adhesives and promote their applications. This research was published in Advanced Functional Materials and selected as the inside front cover article.

溶膠-凝膠相轉變對於離子熱電性能的巨大影響

香港理工大學智能可穿戴系統研究院陶肖明教授團隊製備並研究了幾種不同的相轉變離子熱電系統，首次發現在泊洛沙姆(Poloxamer 407)/LiCl的離子體系中，熱電勢值可以在系統發生相轉變（液體至凝膠，17.4℃）時上升6.5倍（大約2mV/K至超過15mV/K），同時提升離子ZT值23倍(低於0.03至0.68)。該團隊隨即建立基於昂薩格（Onsager）方程的理論模型，分析離子在三個不同階段的遷移（相轉變前，相轉變中及相轉變後）並解釋了熱電勢值提升的來源，即相轉變下溶膠黏度的變化影響陰陽離子的遷移速率，從而造成了陰陽離子在高低溫端的濃度差。作者通過對相轉變前後的模型分析，提出了可能影響離子熱電勢的六個無量綱參數，並提出基於理論分析下熱電勢在相轉變時存在多個數量級提升的可能。通過對理論模型的研究及分析，作者提出了相轉變對熱電效應影響的普適性，即熱電性能的改變不受影響於相轉變的方式，並通過在其他相轉變體系的結果驗證了該結論。該成果提供並揭示了一種全新的設計並控製材料所需熱電性能的可能途徑，這將為室溫下可穿戴設備的低熱能收集應用帶來新的前景。該工作以題為“Gigantic Effect due to Phase Transition on Thermoelectric Properties of Ionic Sol–Gel Materials”發表在《Advanced Functional Materials》上。

智能可穿戴系統研究院團隊獲得 2021 年知識轉移傑出成就校長獎（只有英文版本）

（只有英文版本）Further to the invitation of nominations in February 2021 and the subsequent assessment processes for the captioned, Prof. Xiaoming TAO, director of RI-IWEAR, and Prof. Bingang XU and Dr Tao HUA, two of RI-IWEAR members’ research Yarn-spinning Technology Revolution: Nu-TorquTM have obtained The President’s Awards for Outstanding Achievement in Knowledge Transfer 2021: Industry. A total of five teams was awarded this prize.   Nu-Torque is a revolutionary yarn-spinning technology that uses physical means to create yarns with lower torque and twist while achieving the same strength as conventionally spun yarns. Fabrics made with Nu-Torque yarns are less prone to deformation even after repeatedly washed, while also feel softer, look shinier and with less hairiness. Compared with conventional yarn-spinning technology, Nu-Torque also improves productivity, saves energy and reduces pollutions. Fabrics and garments made with Nu-Torque yarns are widely sold in the U.S., Europe, Japan and China.   Congratulation to our colleagues for the work on knowledge transfer.

準確檢測異常步態並及時給予提示，可增強柏金遜患者行動能力的智能可穿戴系統（只有英文版本）

(只有英文版本)The entire world, approximately ten million people have Parkinson’s disease (PD), which is the second most popular neurodegenerative disease. The most distinct symptoms of PD are movement ("motor") related. Previously reported wearable systems for people with Parkinson’s disease (PD) have been focused on the detection of abnormal gait. They suffered from limited accuracy, large latency, poor durability, comfort, and convenience for daily use. Herewith an intelligent wearable system (IWS) was interdisciplinary research by Prof. Xiaoming TAO and Prof. Margaret Mak, which can accurately detect abnormal gait in real-time and provide timely cueing for PD patients. The system features novel sensitive, comfortable and durable plantar pressure sensing insoles with a highly compressed data set, an accurate and fast gait algorithm, and wirelessly controlled timely sensory cueing devices. A total of 29 PD patients participated in the first phase without cueing for developing processes of the algorithm, which achieved an accuracy of over 97% for off-line detection of freezing of gait (FoG). In the second phase with cueing, the evaluation of the whole system was conducted with 16 PD subjects via trial and a questionnaire survey. This system demonstrated an accuracy of 94% for real-time detection of FoG and a mean latency of 0.37 s between the onset of FoG and cueing activation. In the questionnaire survey, 88% of the PD participants confirmed that this wearable system could effectively enhance walking, 81% thought that the system was comfortable and convenient, and 70% overcame the FoG. Therefore, the IWS makes it an effective, powerful, and convenient tool for enhancing the mobility of people with PD. The research was recently published in Wearable Technologies.
