In smart systems, sensors play an important role because they form the link between mechanical and electronic systems. Magnetic sensors are widely used to measure mechanical quantities because they allow contact-less and, therefore, wear-free measurements. In particular, magnetoresistive sensors can.....

Worldwide electricity demand will rise to 30,116 billion kilowatt-hours in 2030 which is more than double the 2003 level. To control the energy demand and increase the electricity generation efficiency, we have developed a ZigBee wireless sensor network for advanced metering infrastructure. The syst.....

Cubic boron nitride (cBN) is only second to diamonds in terms of hardness and thermal conductivity. However, cBN films are usually thinner and are grown on many substrates, which undermine their hardness, adherence and stability. The multilayer coating (MLC) developed by CityU overcomes the problems.....

CityU inventors have developed a new dielectric waveguide known as dielectric microstrip line (DML). Designed for low-cost millimeter waves and Terahertz front-end systems, the DML does not have any metal conductor, and consists of three dielectric layers. It also has a planar structure that can be .....

Devices consisting of both curved mirrors and conventional lenses systems are known as catadioptrics. Catadiopotrics can shorten the overall optical path length and therefore are popular in telescopes and telescopic camera lenses. This invention aims to develop catadioptric systems capable of genera.....
