卓越研究:拉脹紡織品

拉脹紡織品是一種擁有非傳統特性的纖維性材料，它彎曲時會呈現雙曲線形狀，以及具備高抗凹壓、高能量及震動吸收的能力。這種材料獲廣泛應用於紡織服裝中，例如功能性服裝、防撞設備、醫療護理儀器以及智能可穿戴裝置等。 具有負泊松比的拉脹紡織品在拉伸時會向各個方向膨脹，擠壓時則會收縮。拉脹紡織品材料具有高度的舒適性和靈活性，可應用於在服裝設計。 智能可穿戴研究院成員，紡織及服裝學系胡紅教授透過採用包括紡紗、針織、機織和編織在內的不同類型的紡織技術來改變纖維集合體的結構，研發出一系列拉脹物材料，包括拉脹紗線、拉脹布料和拉脹紡織複合材料。 由於這些新開發的拉帳物料都是源自實驗室，在產初期，團隊遇到不少挑戰，包括缺乏能生產商用、具有復雜的纖維結構的拉帳紡織物的設備。然而，這些挑最終啓發了胡教授自行研發新的生產設備。 此外，由於巿場上並無類似的生產工藝可供參考，因此生產拉帳物料的過程必需經過專門設計。初期因產能有限，導致可用拉脹紡織品供應短缺，限制了商業終端產品的大規模生產。 目前，隨著研究團隊累積了更多實際的生產經驗，他們已推出了更多適合商用的優質拉脹紡織品，同時胡教授的研究亦已經應用於醫療、運動、功能性及防護性服裝，以及可穿載的科技產品等範圍。

壽大華博士榮獲2022年日內瓦發明獎銀獎（只有英文版本）

（只有英文版本）Dr Dahua SHOU, member of Research Institute for Intelligent Wearable Systems, developed a novel fabric that won silver medal in online special edition of the International Exhibition of Inventions of Geneva (Geneva Inventions Expo) - Special Edition 2022 Inventions Geneva Evaluation Days – Virtual Event. The awarded project is Omni-Cool-Dry™: a Desert Beetle Inspired Skin-like Fabric for Dynamic Thermal and Moisture Management. Compared to normal fabrics, this fabric weighs 75% less, dissipates sweat 3 times faster, and is 50% less clingy during heavy perspiration. The wearer’s skin temperature is also 5°C lower. The skin-like fabric aims to keep wearers cool, dry and comfortable by dissipating sweat as water droplets, and by reflecting solar radiation and emitting body heat to the cold universe. The Inventions Geneva Evaluation Days – Virtual Event this year attracted about 800 inventions from 25 countries/regions.

李鸝教授團隊研發出新型遠紅外線纖維（只有英文版本）

（只有英文版本）Prof. Lilly Li, a member of RI-IWEAR, has developed a new way of producing fibres that can absorb and emit far-infrared (FIR) radiation more efficiently than conventional methods. The novel technology can be used to produce high-quality, functional apparel and healthcare products. Unlike the traditional method, Prof. Li’s innovative approach is chemical-free. It is more eco-friendly and cost-effective than the traditional one. It works by modifying the structure of the cross-section of man-made fibres from a conventional circular shape to a triangular one, which is significantly better at both FIR absorption and emission.   The innovation has won Prof. Li a Gold Medal and a Special Merit Award (the Best International Invention, National Research Council of Thailand) at the 47th International Exhibition of Inventions of Geneva 2019 and a Gold Award at the 4th China (Shanghai) International Exhibition of Invention and Innovation 2021.    Please click Excel x Impact Issue 6 to view more detail about the report.

紡織電子交互系統獲得中游研究計劃資助（只有英文版本）

（只有英文版本）Prof. Xiaoming TAO, Director of RI-IWEAR, and Dr Yang CHAI,  recently have secured  approximately HK$5 million under Midstream Research Programmes for Universities from the Innovation and Technology Fund (ITF)  for a 3-year research project entitled “Key Technologies for Textile Electronic Interaction System”.   Human-computer-environment interaction technology has been a recent hot research topic as a result of its applications in smart cities, IoT, AI, VR/AR, and robotics. Interactive textile electronic systems may provide suitable platforms because of their excellent wearable performance and unique immersive features such as lightweight, large-area, handiness, flexibility, comfort, and low strain even under high deformations.   The key to extend the use of these textiles is to develop new technologies for textile-based interaction systems. The project proposes to develop the new technologies by demonstrating prototype system products comprising a modularized fabric display of over 16 million colors, audial communication, fabric keyboard, memory, wireless communication unit and a control unit. In this project, the processing methods for the surface enhancement of flexible fibrous substrates, and fabrication of new double-sided fibrous circuit boards will be investigated. Essential machines and tools will be developed for manufacturing the fabric electronic modules made from electronic yarns, and interconnection between textile electronic modules, as well as determination of processing parameters, quality control methods and procedures. By using the newly developed processes, machines, and tools, Their team will demonstrate novel electronic textile display products for human-computer-environment interaction in smart homes.

他引次數排名前1%的智能可穿戴系統研究院學者 （只有英文版本）

（只有英文版本）Two RI-IWEAR members have been ranked in the top 1% by citation for field and year in the Web of Science released by Clarivate™. The Highly Cited Researchers™ list identifies scientists and social scientists who have demonstrated significant influence through the publication of multiple highly cited papers during the last decade.   Researchers are selected for their exceptional performance in one or more of 21 fields (those used in the Essential Science Indicators™, or ESI) or across several fields. All Highly Cited Researcher records are reviewed. Factors such as retractions, misconduct, and extreme self-citation—all of which would detract from true community-wide research influence—may lead to an author being excluded from the list. The number of those with cross-field influence is determined by finding those who have influence equivalent to those identified in the 21 fields. For 2021 Highly Cited Researchers analysis, the papers surveyed were the most recent papers available to us—those published and cited during 2010-2020 and which then ranked in the top 1% by citations for their ESI field and year (the definition of a highly cited paper).   Congratulations to our colleagues on their ranking in the top 1% by citation for field and year in the Web of Science released by Clarivate!

新研究文章在科學進展發表（只有英文版本）

（只有英文版本）The rapid development of edge devices highly demands low-power electronics for effective data acquisition and intelligent information processing. The power consumption of an individual device is proportional to the square of the voltage. To reduce the operation voltage of electron devices, Dr. Yang Chai’s research team demonstrates a new type of transistor with sub-1 V operation voltage, which is recently published in Science Advances 2021, 7: eabf8744. They adopt atomic-level thick two-dimensional (2D) semiconductor as the channel of a transistor and transfer metal gate to 2D MoS2 for forming a high-quality interface at room temperature. The high–barrier height Pt-MoS2 Schottky junction replaces the commonly used metal-oxide-semiconductor capacitor and has intrinsically high junction capacitance and a high-quality interface. This MoS2 transferred metal gate (TMG) field-effect transistor shows sub-1 V operation voltage and a subthreshold slope close to the thermal limit (60 mV/dec). The TMG and the back gate of the TMG transistors enable logic functions in a single transistor with a small footprint, exhibiting promising low-power applications for edge computing.
