PolyU’s novel lightweight Textile Lithium Battery demonstrates high energy density of more than 450 Wh/L, and excellent flexibility—with a bending radius of less than 1mm, and foldability of over 1,000 cycles with marginal capacity degradation. In comparison, the existing bendable lithium battery can only reach a bending radius of about 25 mm, and with much […]
A New Semiconductor Nanofibre Could Greatly Increase the Effectiveness of Solar Cells
A team from The Hong Kong Polytechnic University (PolyU) developed a novel nanostructure embedded into a semiconductor nanofibre that results in superb conductivity. The nanocomposite addresses a key inhibitor to conductivity, with the potential to improve a wide range of applications, from batteries and solar cells, to air purification devices. While semiconductors are widely used, […]
Team Develops Accurate Contactless 3-D Fingerprint Identification System
The research team of The Hong Kong Polytechnic University (PolyU) has developed a system for three-dimensional (3D) fingerprint identification by adopting ground breaking 3D fingerprint minutiae recovery and matching technology, pushing contactless biometric technology into a new realm of speed and accuracy for use in identification, crime investigation, immigration control, security of access and forensic […]
Team Breaks World Record of Fastest Optical Communications for Data Centers
The Hong Kong Polytechnic University (PolyU) has achieved the world’s fastest optical communications speed for data centres by reaching 240 G bit/s over 2km, 24 times of the existing speed available in the market. Compared to existing alternatives in the market, the technology developed by PolyU has reduced the cost of data transmission per unit […]
Photos of the Day: Smart Wheelchair Integrates Environment Control, Safety Monitoring
The Hong Kong Polytechnic University (PolyU) has developed an intelligent system called “iWheelchair”, integrating a series of advanced PolyU technologies from its Interdisciplinary Division of Biomedical Engineering (BME) and Institute of Textiles and Clothing (ITC). With a tablet computer as the centralized operation platform, the system integrates a variety of functions such as environment control, […]
Low-Cost, Contactless and Accurate 3D Fingerprint Identification System
Traditional fingerprint identification by pressing or rolling of finger against the hard surface often results in partial or degraded images due to improper finger placement, skin deformation, slippages, or smearing. Therefore touchless 3D finger imaging can provide more accurate personal identification as rich information is available from 3D fingerprint images. This project at the Hong Kong […]
Team Develops Novel Intelligent Transportation System for Personalized Reliable Driving Routes
PolyU has been assisting the HKSAR Government in the development and application of real-time intelligent transportation systems, including the “Real-time Traffic Information System”, “Hong Kong eRouting” and “Hong Kong eTransport” available on the Hong Kong Transport Department’s website, as well as journey time indicators like “Journey Time Indication System”, and “Speed Map Panels”. The real-time […]
