The Hong Kong Polytechnic University (PolyU) has won a total of 10 prizes for its multi-faceted innovations presented 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 and enhanced the well-being of our society on different fronts.

A few of these are:

Gold Medal with Jury’s Commendation:

Fast Fabric Hand Measurement Technology

Principal Investigator: Professor Li Yi, Institute of Textiles and Clothing

The development of new fabrics and hence comfortable clothing is an ongoing challenge for researchers in the field of textile science. With this in mind, PolyU researchers have successfully made use of fast bionic technology to measure and simulate hand touch sensations of “soft-stiff”, “smooth-rough” and “warm-cold”.

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”, “smooth-rough” and “warm-cold” and final preferences.

This project is jointly undertaken by the University’s Institute of Textiles and Clothing and Hong Kong Research Institute of Textiles and Apparel (HKRITA).

Gold Medal:

Imaging Colour Measurement System based on Multispectral Imaging Technology

Principal Investigator: Professor John Xin, Institute of Textiles and Clothing

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.

This project is jointly undertaken by the University’s Institute of Textiles and Clothing and Hong Kong Research Institute of Textiles and Apparel (HKRITA).
