RI-IWEAR Members Obtained The President’s Awards for Outstanding Achievement in Knowledge Transfer 2021

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.

RI-IWEAR Members Won Two Awards at TechConnect World Innovation 2022

Prof. Hong HU, Dr Dahua SHOU and Prof. Jintu FAN, members of Research Institute for Intelligent Wearable Systems (RI-IWEAR), won two prestigious global innovation awards in the areas of materials science and biotechnology at the TechConnect World Innovation Conference and Expo 2022 - the world’s largest multi-sector event for fostering the development and commercialisation of innovations.   The award-winning innovations include a new type of more environment-friendly moisture-absorbing and sweat-releasing fabric and an automatic temperature-controllable mask. Details are as follows: Moisture-Absorbing and Sweat-Releasing Multilayer Polylactic Acid Fabric and Manufacturing Technology (Prof. HU Hong, Institute of Textiles and Clothing) The new fabric stands out from existing moisture-absorbing fabric technology in that its fabrication technique is simpler, cheaper, and more environment-friendly. By employing double weft knitting technology, it only takes one single manufacturing process to produce the new fabric structure with improved moisture-absorbing and sweat-releasing properties. It also has inherent biological resistance and is ideal for use in school uniforms and sportswear. Omni-Cool-Breath: A Smart Air-Conditioned Mask (Dr SHOU Dahua, Professor FAN Jintu and Dr HUANG Guanghan, Institute of Textiles and Clothing) Omni-Cool-Breath is the first automatic temperature-controllable mask that brings revolutionary access to all-day cool breath and thermal comfort under various activities and thermal conditions. It reduces temperature by 12°C and humidity by 65% under low voltage via an innovative miniature thermoelectric cooling system. The ergonomically designed lightweight mask uses skin-friendly and biodegradable 3D printing materials that enable the user to enjoy nine hours of clean air.   For more information of the TechConnect 2022 Innovation Awardees, please visit the official website: https://www.techconnectworld.com/World2022/participate/innovation/awards.html

Professor Feng YAN’s Team Develops Ultrasensitive and Portable Detection Sensor for Rapid, Easy and Low-cost COVID-19 Antibody Test

Professor Feng YAN’s team has successfully developed an ultrasensitive and portable COVID-19 antibody detection sensor based on organic electrochemical transistor (OECT) technology. Fast and easy-to-use, the sensor is designed for testing the antibody levels of people who have either received vaccination or have been infected with the virus.   The whole detection process, which uses saliva sample instead of only blood, takes less than six minutes and the cost per test is only about HK$10. The antibody detection sensor can test the concentration of antibodies from lower than 10fM to higher than 100nM. The detection limit satisfies the needs of exquisite analytical sensitivity for saliva.   Professor YAN said that since the detection process is non-invasive, self-sampling is highly possible. Moreover, the operation and result reading are very simple with the use of a smartphone, and hence the sensor is suitable for instant detection and large-scale screening scenarios.   The next plan of the research team is to apply for funding for clinical studies in collaboration with different medical and testing institutions. They expect that the novel device can be commercialised as soon as practicable and applied for antibody detection of other viruses.

Scalable Production of Ultrafine Polyaniline Fibres for Wearable Electronics

High performance conducting polymer fibres are highly demanded in fields from advanced fibrous devices to frontier fabric electronics. Recently, a joint research team, led by Prof. Xiaoming TAO and Dr Yang CHAI, reported a scalable good solvent exchange strategy to produce ultrafine polyaniline (PAni) fibres. This work was published at Nature Communications. The first authors are Dr. Fang Bo and Mr. Jianmin Yan.   Processing conducting polymers into macroscopically fibrous materials makes it possible to translate their nano-object features to human-friendly products in a continuous manner. Primarily due to the large diameters, the performance and expectations of most achieved continuous conducting polymer fibres (CPFs) have been limited by their insufficient electroactive surfaces and weak tensile strength. Tao’s group report a good solvent exchange strategy in a modified wet spinning technique to prepare the ultrafine PAni fibres (UFPFs) at the large scale. Beyond conventional wet spinning protocol, they replaced poor solvents by good solvents as the coagulation bath to decrease the viscosity of gel protofibres, which were subject to an ultrahigh drawing ratio and reduced to an ultrafine morphology. In the modified one-step wet spinning process, they used good solvents as the coagulation bath to realize the mass production of UFPFs. A decreasing of diameter from ~0.1 mm to ~4.7 µm was observed, which is a record small value in the achieved wet-spun CPFs. The ultrafine fibre shows a smooth surface, highly crystallized microstructures, and uniform electrical properties. Moreover, such an impressive drawing ratio enables a very high production efficiency of UFPFs beyond 40 meters per minute.   UFPFs show impressive mechanical performance and energy storage abilities. UFPFs have a modulus of 29.89±5.6 GPa, and a strength of 1080±71 MPa, at least one order of magnitude higher than that of CPFs with larger diameters. They used polyvinyl alcohol (PVA)-H3PO4 gel electrolyte and two UFPF electrodes to construct a micro capacitor to evaluate the electrochemical activity of UFPFs. The area capacitance is between 1008 and 1666 mF cm-2 at the current densities between 0.32 and 3.18 mA cm-2, outperforming previously reported thick CPFs and other electrodes, and approaching to that of PAni nanowires. Benefitting from the favorable energy and charge storage performance of UFPFs, they demonstrated a high-performance all-solid organic electrochemical transistor (OECT), which is very soft, and shows favorable amplification performance with a high on-off current ratio (>103) at low voltages (
