Prof. Lilly Li’s Team Developed New Far Infrared Fibre

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.

Midstream Research Scheme Funding Secured for Textile Electronic Interaction System

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.

RI-IWEAR Scholars Ranked in the Top 1% by Citations

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! This recognition demonstrates RI-IWEAR’s influence in multiple disciplines and signifies our dedication to conducting world-class research in wearable technology.   RI-IWEAR's Scholars Ranked in the Top 1% by Citations  Name (by alphabetical order of surname)  Category               Prof. Gang LI  Cross-Field  Prof. Feng YAN  Cross-Field

New Publication in Science Advances

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.

RI-IWEAR’s Works are Recorded in the HKRITA Centre Report

RI-IWEAR members' work Green Textile Research and Far-Infrared Functional Textiles are introduced at the latest centre report of The Hong Kong Research Institute of Textiles and Apparel Limited (HKRITA) that is funded by the Innovation and Technology Commission of the HKSAR Government and hosted by The Hong Kong Polytechnic University. This kind of Green Textile developed by RI-IWEAR Director Prof. Xiaoming TAO and Dr. Polly LEUNG is a blend of PLA and PHBV, have proven to be an eco-friendly yet equally durable alternative to synthetic fibres. The anti-bacterial properties of the PLA/PHBV fabric have been confirmed that has up to 99% against Cocci, Escherichia coli, Candida Pasteurella, and that PHBV oligomers can destroy the bacterial cell wall layer by layer. This bio-based textile is not only odour-resistant, but also repels superbugs like the more dangerous and notoriously drug-resistant Staphylococcus aureus, preventing tough-to treat cross-infections. Prof. Li LI and Prof. Feng YAN cooperate to develop the new Far-Infrared functional textiles. This textile is combined physical methods with an optical simulation system and provide better thermal protection than traditional far-infrared ones that are made of chemicals such as metallic oxide, nonmetallic oxide and metal, while also promoting blood circulation and metabolism.
