Follow on Google News | PolyU wins top prizes in Geneva’s Invention ExpoPolyU has won a total of 10 prizes for its innovations at the 41st International Exhibition of Inventions of Geneva. Not only have these breakthroughs brought glory to Hong Kong, but also extended the frontiers of knowledge.
(1) Grand Prize and Gold Medal: Intelligent Ship-Bridge Anti-Collision Surveillance System Principal Investigator: This novel system functions as a “black box” of the bridge to provide a full record of ship activities near the bridge area and impact to the bridge structure. By incorporating Automatic Identification System (AIS) and smart vision-based monitoring technology into the security of bridge, this system can actively monitor marine traffic, evaluate the route of ship movements and send out warning signals to the ships likely to collide with the bridge. Novel piezoelectric sensor arrays are embedded in the bridge as well to build up a new method for impact force monitoring and collision damage evaluation. (2) Gold Medal with Jury’s Commendation: Fast Fabric Hand Measurement Technology Principal Investigator: Fabric-skin touch sensations influence our feelings and sense of happiness in sleeping, walking, running, working, sporting and shopping. How to measure fabric tactile properties quickly is an important issue for selecting appropriate fabrics for a specific purpose in designing apparel and textile products, so that consumers can make good decisions and enjoy the products they purchased. In accordance with the neurophysiological mechanisms of human sensory perceptions, a novel bionic instrument has been developed by PolyU researchers to simulate how fabrics stimulate human skin sensory receptors, generate signals, transmit to human brain and formulate sensations like “soft-stiff” (3) Special Prize and Gold Medal: Novel Flavonoid Dimers for Reversing Cancer Drug Resistance Principal Investigators: Although chemotherapy is extensively used in cancer treatment, multidrug resistance (MDR) remains a major problem. PolyU researchers have designed small molecules to reverse this process. Membrane proteins P-glycoprotein (P-gp) and Breast Cancer Resistance Protein (BCRP) pump drugs out of cancer cells and reduce chemotherapy efficacy. Moreover, they have designed, synthesized and characterized novel diet-derived flavonoid dimers which can target P-gp and BCRP’s dimeric structure. Due to the unique design of dimeric in structure which can specifically bind to the pseudodimeric P-gp and BCRP, these flavonoid dimers can inhibit P-gp and BCRP, and reverse cancer drug resistance with very high potency (inhibiting BCRP at < 1 nM) and low toxicity (therapeutic index of 1x105). (4) Special Prize and Gold Medal: Online Monitoring System for High Speed Laser Spot Welding Principal Investigator: In the area of industrial micro-joining, laser welding has probably become the most preferred process as it does not involve soldering and offers high production rate. However, there is no practical welding monitoring technology which suits the stringent requirements in mass-production line. This PolyU-developed system can monitor the welding process quality of very tiny and sophisticated electronic components. In milliseconds, it can identify the welded spots quality based on reflected infra-red signals and the cooling rate of the spots. The invention can enhance efficiency and quality in the manufacturing of consumer electronic products such as mobile phones and medical products, in which micro-welding of metallic parts and hermetic sealing are the most critical factors. (5) Gold Medal: An Energy-Saving, Wide-Colour Gamut LED Display System Principal Investigators: The proposed system employs a low-cost method for implementing the multi-level Pulse-Width- (6) Gold Medal: Imaging Colour Measurement System based on Multispectral Imaging Technology Principal Investigator: This Imaging Colour Measurement (ICM) system is the world’s first measurement instrument capable of measuring spectral reflectance over the visible spectrum in the range of 400 to 700 nanometres, with a very high accuracy up to 0.0024 in terms of root-mean-square spectral error. It measures colours of multi-colour samples ranging from printing fabrics, yarn-dyed fabrics, laces, yarns, threads, to coloured plastics, cosmetics, as well as automotive parts. Moreover, the colour measurement capability of ICM system can be further extended to any multi-coloured, irregular shaped, extremely small 3-dimensional objects. This PolyU-developed ICM system has completely overcome the limitation of measuring any multi-colour sample by a spectrophotometre which is currently the only type of accurate spectral colour measurement device available in the market. (7) Bronze Medal: Smart Garment with Traditional Chinese Herbal Medicine Microcapsules for Treating Atopic Dermatitis Principal Investigators: It is commonly known that Traditional Chinese Herbal Medicine (TCHM) can be directly applied to the skin for clinical treatment by Chinese bone-setters and TCM practitioners. However, this old-fashioned method may make patients uncomfortable and the release of TCHM could not be controlled for effective treatment. Thus, a new method is developed to prepare Chitosan/Sodium Alginate microcapsule encapsulated with TCHM for effective clinical treatment without toxicity effect, and with the ability of controlled-release over time. The TCHM microcapsules are grafted on special textile materials to develop smart garment for more convenient and effective curing of patients with atopic dermatitis. ***** Press contact: Ms Idy To Assistant Director, Institute for Entrepreneurship Tel: (852) 3400 2808 Email: idy.to@polyu.edu.hk End
