Award-winning Project by RI-IWEAR member: Omni-Cool-Dry™: a Desert Beetle Inspired Skin-like Fabric for Dynamic Thermal and Moisture Management

Dr Shou Dahua, a member of the Research Institute for Intelligent Wearable Systems (RI-IWEAR), developed a desert beetle inspired skin-like fabric, which promises all-day cool, dry, breathable, and comfortable feelings under dynamic thermal conditions. This unique fabric quickly dissipates excessive sweat as water droplets to avoid sensation of wetness and saturation. It also reflects solar radiation and emits body heat to the cold universe for cooling. Compared to conventional fabrics, 𝘖𝘮𝘯𝘪-𝘊𝘰𝘰𝘭-𝘋𝘳𝘺™ weighs 75% less, dissipates sweat 3 times faster, and is 50% less clingy during heavy perspiration. The human skin can be cooled by 5°C lower than with a commercial cotton fabric. This fabric will help the outdoor enthusiasts and athletes to perform the best. It will also be desirable to professionals such as medical personnel, construction workers, and firefighters for more endurance.

Award-winning Project by RCDSE: Camera Pointing System for China’s Lunar Exploration Missions (Chang'e 3 and 4)

The precision robotics research team led by Professor Yung received the Gold Medal with Congratulations of the Jury at the Geneva Inventions Expo 2022 for the project “Camera Pointing System for China’s Lunar Exploration Missions (Chang'e 3 and 4)”. PolyU is the only university in Hong Kong taking part in the Nation’s space missions and actively contributing to the national space technology. The awarded project entitled “Camera Pointing System for China’s Lunar Exploration Missions (Chang'e 3 and 4)”. Installed on top of the lunar lander, it facilitates panoramic image capturing and rover movement observation on the moon, and helps construct a precision 3D model of the landscape for safe rovering. With a complex design and a weight of only 2.8 kg, it is sturdy enough to protect the camera against shock and vibration during the space mission and ensure its proper functioning under the extreme lunar environment. The invention was completed and successfully deployed on the Moon front surface with the Chang’e 3 and Moon far side with the Chang’e 4 missions of China’s Lunar Exploration Programme.

Award-winning Project by RILS member: Umicool: an Eco-friendly Smart Sub-ambient Radiative Cooling (SSRC) Coating

A team led by Prof. Jianguo Dai, Management Committee Member of the Research Institute for Land and Space (RILS) and Founder of Pro-Infra Science & Technology Limited (a PolyU Academic-led start-up), developed the eco-friendly, long-lasting, self-cleaning, low-cost polymeric radiative cooling coating which can reduce the interior temperature of buildings/infrastructure by 6°C as compared to the ambient temperature under direct sunlight without electricity consumption. UmiCool can scatter sunlight, convert absorbed UV light to fluorescence emissions and re-emit infrared radiation to the cold universe. The project received a Gold Medal in this year’s online special edition of the Geneva Inventions Expo recently.

Important Progress made by RI-IWEAR in Efficient and Scalable Moisture-Electric Generators made from Ionic Hydrogel

In the context of global resource shortage and high demand for carbon neutrality, it is of great significance to find simple and efficient green energy conversion technology to achieve sustainable development of energy and society. Moisture-electric generator (MEG) is based on the chemical energy from atmospheric moisture to generate electricity directly, without the generation of pollutants and harmful gas emissions, which is an emerging research focus in the energy field. However, most MEGs suffer from intermittent electrical signals and low current. In addition, the realization of large-scale integration and practical applications is still the bottleneck of current research. To address this issue, Prof. Tao’s research team have developed a novel and efficient ionic hydrogel moisture-electric generator (IHMEG), which converts the chemical energy released by captured moisture in the air into electricity, realizing efficient current density and power output. A single IHMEG unit of 0.25 cm2 can continuously generate direct-current electricity with a constant open-circuit voltage of ~0.8 V for over 1000 hours, a high short-current density of 0.24 mA·cm-2 and power density of up to 35 mW·cm-2. Of great importance is that large-scale integration of IHMEG units can be readily accomplished to offer a high voltage of up to 210 V, making the flexible IHMEG assembly capable of directly driving numerous commercial electronics, including electronic ink screen, metal electrodeposition setup and even light-emitting-diode arrays. This IHMEG device with high cost-efficiency, easy-to-scaleup fabrication and high power-output opens a brand-new perspective to develop a green, versatile and efficient power source for Internet-of-Things and wearable electronics. The work is published in Advanced Materials (https://doi.org/10.1002/adma.202200693) recently. The first author is a PhD graduate, Dr. Yang Su.

RiFood's study reveals Bifidobacteria almost non-existent in cesarean-born Chinese babies

A research by Dr Jiachi CHIOU, Associate Director of RiFood has revealed that Bifidobacteria, a probiotic, was nearly non-existent in the gut of babies born by cesarean section (C-section). Bifidobacteria is viewed as an essential probiotic for proper immune development and good gut health among infants which protects the neonates from various intestinal and immunity disorders. Dr Chiou and her research team examined 70 fecal samples of newborn babies after their first 2 weeks of life for the study. They found that the Bifidobacterium species almost did not exist in samples from C-section babies. In comparison, 37 fecal samples from vaginally birthed, breastfed babies had the necessary probiotic levels. While previous study suggested that Bifidobacteria could be detected from the breastmilk, and hence breastfeeding may help to supplement the beneficial bacteria in the baby’s gut microbiota. Dr. Chiou also said 38% of births in Hong Kong are C-section deliveries, so it is crucial to understand the special nutrition needs of C-section babies.
