Smart Materials, Devices, and Applications

The research in smart materials, devices, and applications is a strategic technology resource to facilitate sustainable development of electrical engineering (and its related science, technology, and engineering fields) into newer and smarter dimensions.

Supported by the well-equipped Smart Materials and Systems Laboratory, the research group has the primary focus on developing multifunctional smart materials with interestingly high magneto-/electro-/thermo-/mechano-/optical responses in the bulk, micro-, and nano-scale. It also aims to investigate the fundamentals of energy generation, conversion and storing processes, structural integrity as well as environmental sustainability for multidisciplinary applications of the materials. The smart materials of interests include, but are not limited to, multiferroic, magnetoelectric, ferroelectric, piezoelectric, magnetostrictive, magnetocaloric, ferromagnetic shape memory, magnetorheological, and photovoltaic materials. Moreover, the development of smart devices, including power supply-free energy-harvesting wireless sensors, coil-free self-isolated circuit protection and control devices, electromagnetic wave nano-absorbents, green batteries and energy cells, sensori-actuators/-transducers, ultrasonic motors, self-sensing vibration absorbers/isolators/dampers, etc., forms the application focus. In addition, condition and health monitoring; signal analysis, processing and transmission; drives, control and automation; energy harvesting, conversion and storage; prognosis and diagnosis; nondestructive evaluation; etc. are the synergic technologies for integrated systems.

The research group has an outstanding record of research performance and an excellent reputation for professional services in the three aspects of basic research, applied research, and industrial research, both locally and internationally.

The photonics research activities at the Department of Electrical Engineering covers a wide range of science and technology applications, including specialty optical fibre designs and fabrications within silica and polymer materials, fibre lasers, fibre sensors and their applications in gas sensing and structural and condition-monitoring, long-haul optical fibre communications and short-distance links for data center and big data applications, laser nano-/micro-fabrication technologies, lab on a chip, and flexible optoelectronic devices. The Photonics Research Centre hosted by the Department houses many state-of-the-art facilities which include:

1. fibre drawing towers for fabrication of specialty silica/plastic optical fibres,

2. maskless exposure platforms for fabrication of micro-structures and devices,

3. several laser-based platforms for making gratings and other micro-structures in fibres and waveguides, and

4. high-speed optical fibre transmission equipment (supports Tbps over 1,000’s km) for research in high-performance optical fibre communication systems.

The Department is also involved in many industrial R&D projects:

1. designed and built the world’s first city-wide optical fibre sensing networks to monitor operation condition of trains of all urban lines in Hong Kong,

2. developed 100 Gb/s and 1Tb/s optical fiber transmission systems with Huawei Co. Ltd, NEC and Corning.

Power Electronics

Power electronics is to use effective method of electronics to control the power processing. The major research areas include the static power conversion and motion control. The key development is to achieve high efficiency, high power density and high performance system based on high frequency and soft-switching techniques, this together with new control method, new machine and magnetic design will form the elements for power electronics innovation. Areas of study include converter topology analysis, switched-capacitor converters, integrated magnetics, low profile magnetics, inductive power conversion, high power converters, multi-level converter, power quality control converter, LED lighting, wind power generator, high power photovoltaic energy storage processing, and battery, fuel cell and super capacitor energy management. For the motion control areas, switched-reluctance machine design and driver analysis, resonant inverter drives, robotic control, generator design and control, and wind power processing are promising areas of future development.

The Department is also developing new areas in electric vehicle, high speed transportation, electric vessel, electric aircraft, alternative energy, medical power electronics, electromagnetic compatibility, DC and high frequency AC power distribution. The Department is also actively involved in commercial development in automotive engineering. The pioneering works are vehicle air-conditioning, solar vehicle, in-wheel motor, vehicle integrated charger and motor drive, high power charger, wireless charger, battery management system, vehicle control unit, body integrated energy storage, electric vessel, active suspension and drive-by-wire.

Power and Energy Systems

The complexity of power systems has increased drastically due to the continuing growth of interconnections between power grids and diverse sources of electricity, the advancement of new technologies and the need to address economic and environmental constraints. Widespread deregulation of the electricity supply industry and the promotion of renewable energy and electric vehicle usage have further added to the complexity of management of power systems. Research on emerging power and energy systems is essential for developing efficient and reliable power grids for the future; i.e., smart grids.

Electrical power engineering has long been the area of excellence within the University, and the Department is the only one that can provide heavy current electrical engineering programs of both education and research among all universities in Hong Kong. The Department has an excellent record of achievements in a wide range of research areas such as power system planning and operation, system protection, stability and control, power quality and harmonics, renewable energies integration, electric vehicle charging, energy and power markets and demand side management. Recent focuses also include artificial intelligence (AI) and big data analytics applied to smart grid and smart city development.

The Department has been actively involved in many high-level research and consultancy projects such as two HK SAR Government Theme Based Research Scheme Projects on smart solar energy and smart grid development. Our strategic partners include research institutions and industrial partners from Hong Kong, Mainland China, USA, Canada, Australia and Europe with whom joint research projects and research publications have been undertaken. The Department is also involved in developing commercial grade software packages for industrial applications.
