A team from The Hong Kong Polytechnic University (PolyU) has developed a novel nanostructure embedded into a semiconductor nanofiber 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…

A new system improves the speed and accuracy of fingerprint scanning and matching by using 3-D technology. No pressing required. A new system for contactless, three-dimensional (3-D) fingerprint identification has an advanced design that is not only an improvement over 2-D scanners, it is also more compact and less costly than other 3-D systems. “We…

The Hong Kong Polytechnic University (PolyU) research team developed a novel breed of nanocomposites-inspired sensors which can be sprayed directly on flat or curved engineering structural surfaces, such as train tracks and aeroplane structures. The sprayed sensors can be networked, to render rich real-time information on the health status of the structure under monitoring. Due…
