CityU CUBIC forum on printed electronics

Dr Victor Lau

Dr Roy Vellaisamy

Prof Xu Haisheng

I n a forum organized by the CityU Business and Industrial Club (CUBIC) on 17 August 2012, three speakers from CityU and mainland China talked about the overall development of printed electronics and their applications.

Dr Victor Lau, Technology Transfer Officer of the Knowledge Transfer Office (KTO), gave an overview of the history of printed electronics. According to Dr Lau, the industrial use of printed electronics can date back to the 1930s when circuit boards were first printed with conductive inks. Recent interest in printed electronics has been fuelled by the growing popularity of RFID technologies, driving the creation of better inks and more diverse applications. Flexible electronics, an offshoot of printed electronics, is particularly attractive since it may contribute to human-machine interfacing and flexible displays that seek application in entertainment, fashion, architecture, OLED lighting and photovoltaics. Dr Lau pointed out that by 2021, the market share of printed electronics will go through a twentyfold increase, with most robust growth in OLED displays and photovoltaics.

The second presentation by Dr Roy Vellaisamy from the Department of Physics and Materials Science focused on contemporary application of printed electronics. Dr Vellaisamy said that unlike conventional electronics, printed electronics have low integration density, simple fabrication, and extremely low fabrication costs. Printed electronics’ relevance to

memories, sensors, and photovoltaics was discussed in length. One of the products enhanced by printed electronics is printed RFID tags used for authentication and logistics. Dr Vellaisamy has also applied printed electronics to the development of solar cells and flexible amine sensors.

The last speaker, Professor Xu Haisheng of the East China University of Science and Technology, talked about the development of printed electronics in China, in particular its industrial applications. According to Professor Xu, printed electronics has a huge market in China, as evidenced by the fast growth of the RFID and printed circuit board industries in the nation. He anticipated that the future growth of printed electronics in China would focus on circuits, transistors, memories, and batteries. Professor Xu is also chairman and president of Kunshan Hisense Electronics Co Ltd.

CityU technologies transferred in 2012

HKTDC forum on intellectual property


T he three licensing deals closed in 2012 have brought about the commercialization of a wide range of CityU technologies, including:Maximum power-point tracking Principal Investigator: Professor Henry Chung (Department of Electronic Engineering)The technology maximizes the amount of energy to be captured from photovoltaic modules or solar panels by making use of the characteristics of the converter, and that the solar panel and converter can be treated as one single unit.

Micropulse lidar systemPrincipal Investigator: Dr Andrew Cheng (ex-CityU staff)The micropulse lidar system developed by CityU is used for atmospheric aerosol cloud profiling, pollution monitoring, and climate modelling.

Organic electroluminescent devicesPrincipal Investigator: Professor Lee Shuit Tong (ex-CityU staff)The organic electroluminescent devices have improved hole injecting structures and a buffer layer between the anode and the luminescent medium. Compared with devices without the buffer layer, CityU’s organic light-emitting devices may be more efficient in a proper bias condition.

Organic light-emitting devicesPrincipal Investigator: Dr Hung Liang Sun (ex-CityU staff)The novel organic light-emitting devices are distinguished by their lower levels of ambient-light-reflection, compared with other similar products. The reflection-reducing structures in the devices are prepared by conventional thermal evaporation without incurring damages to the organic materials.

Plasma immersion ion implantation (PIII)Principal Investigator: Professor Paul Chu (Department of Physics and Materials Science)The PIII technique enjoys wide application in surface treatment. It can significantly enhance the properties and performance of industrial parts and surgical tools, while limiting the undesirable effects common to other similar surface treatment techniques.

Semiconductor transformersPrincipal Investigator: Professor Ron Hui (ex-CityU staff)Unlike traditional transformers which are usually magnetic, the CityU transformers are made of semiconducting materials, and therefore can be fully incorporated into integrated semiconductor electronic circuits.

I ssues relating to intellectual property (IP) trends and strategies were discussed in the Business Intellectual Property Asia Forum organized b the Hong Kong Trade Development Council (HKTDC), with City University as one of the supporting organisations of the event.

The forum took place on 7 December 2012 at the Hong Kong Exhibition and Convention Centre. It was kicked off with opening remarks by the HKSAR Secretary for Commerce and Economic Development Mr Gregory So and HKTDC’s Executive Director Mr Fred Lam. IP practitioners from Europe and the US

spoke on topics including the latest IP trends, IP trading, the Chinese market, valuation of IP, and licensing.

Useful analysis on IP and its impact on economic growth was presented in panel discussion sessions. Mr Wolf Meire-Ewert, Counsellor on Intellectual Property of World Trade Organisation, used information technology as an example to show that technological innovation brings about downstream innovation in sectors that absorb the technology, and for that reason, technological change is essential to economic growth.

The expansion of the Madrid and Hague systems of trademark registration is another example of how IP protection can benefit small-and-medium-sized enterprises, and not just multinational corporations, as pointed out by Mr Gregoire Bisson of the World Intellectual Property Organisation.

As the commercialization of IP undergoes a momentous growth, much attention is focused on IP valuation. Mr Jesper Kongstad,

Director General of the Danish Patent and Trademark Office, pointed out that IP valuation poses a major challenge to IP trading because IP is intangible. Commenting on the same issue, Mr Ricky Lee of the American Appraisal China Limited proposed that valuation of IP should take into consideration the estimated market size, economic benefits, risk and economic benefit period.

Another major theme addressed by the forum is IP development in China, and how do businesses echo with it. Speakers invited to present on the topic were Mr Peter Cheung, Director of HKSAR’s Intellectual Property Department, Mr Liu Yanxin, Director General Assistant of the China Patent Information Center, and Mr Saif Aziz, Director of Technology Alliance of IBM Greater China Group.

Over 1,300 participants from around the world attended the forum, held concurrently with the HKTDC’s World SME Expo and Inno Design Tech Expo.

CityU CUBIC Happy Hour Tea Gatherings

I n the latter half of 2012, several Happy Hour Tea Gatherings were organized for members of the CityU Business and Industrial Club (CUBIC) of the Knowledge Transfer Office. Challenges facing the local construction sectorIn the gathering dated 29 June, Professor Tam Chi Ming and Mr Thomas Ho, both prominent members of the local construction sector, were invited to give speeches on issues relating to the challenges and opportunities in store for the sector.

Professor Tam of CityU’s Department of Civil and Architectural Engineering pointed out that major infrastructural projects were going to exacerbate the shortage of construction workers in Hong Kong. Public works such as the construction and maintenance of housing estates, MTR lines, and airport facilities, as well as an ageing workforce, may fuel the demand for labour in the next three to four years.

Mr Thomas Ho, Chief Executive of Gammon Construction Limited, outlined the global and local development of the construction and in particular the importance and application of Building Information Models (BIM). BIMs are digital representations of a building that support the entire lifecycle of a building project, providing crucial information for cost management, construction logistics, operation and maintenance and demolition etc. According to Mr Ho, BIMs are widely used in countries such as USA, Korea, and Singapore. To promote the application of BIMs in Hong Kong, long-term strategies and implementation guidelines should be drawn up.

Mr Ho and Professor Tam are respectively Chairman and Vice-Chairman of CUBIC’s building and construction group.

freshness of food products. Dr Lam’s sensors are responsive to vapours of biogenic amines and hence no contact with the food is required. Upon detection of target contaminants, the sensor will give off a luminescent glow that lingers on even after the contaminants are removed.

The third presentation by Dr Shengchun Wu of the State Key Laboratory in Marine Pollution focused on the Lab’s objectives and major research hotspots. The Lab champions pollution monitoring technologies, marine ecology, risk assessment, pollution control, and bioremediation measures. Supported by leading academicians and scientists, the Lab is committed to tackling marine pollution issues in an attempt to protect the marine ecology of mainland China and Hong Kong.

Professor Shahabi

Patents granted to CityU in 2012Apparatus and method for controlling the output phase of a VCOUS patent number: 8138841

Inventor: Professor Xue Quan, Department of Electronic Engineering

Dr Wan Kwun Chiu, ex-CityU staff

The invention disclosed in this patent relates to a method and apparatus for controlling the output phase of a Voltage Controlled Oscillator (VCO), thereby improving the performance of antenna arrays when receiving radio signals. However, the various techniques for implementing the use of adaptive receiving arrays can be costly, complex, and inefficient. To remedy these problems, the inventors have developed a method for controlling the output phase of a VCO whereby the phase shifter is positioned on a feedback path between the VCO and a feedback input of the phase locked loop. The phase of a feedback signal on the feedback path can be shifted by either a fixed or variable phase shifter. As a result, the output phase of the VCO can be controlled and adjusted by a desired amount in a controlled manner. The apparatus described here may provide a higher resolution phase shift of the output signal and greater accuracy in a relatively simple and inexpensive way.

Method of fabrication of cubic boron nitride conical microstructuresUS patent number: 8158011

Inventors: Professor Lee Shuit-tong, ex-CityU staff

Professor Igor Bello, ex-CityU staff

Professor Zhang Wenjun, Department of Physics and Materials Science

Dr Zou Yousheng, ex-CityU staff

Dr Chong Yat Ming, CityU graduate

Dr Ye Qing, CityU graduate

Cubic boron nitride (cBN) possesses a wide array of outstanding properties similar to and/or even superior to diamonds. However, the fabrication of cBN nanostructures, such as nanocones, is limited by the extreme mechanical toughness and chemical inertness of cBN, and the difficulties of forming good-quality cBN films. To address the problem, the research team has devised a new method of fabricating cBN conical structures and their arrays. The procedures of fabricating cBN conical structures include depositing a cBN film on a diamond layer, depositing etching masks on the cBN film, and finally reactive ion etching (RIE) of the cBN film. The diamond layer beneath the cBN film provides the structural compatibility, high adhesion, and supporting capacity for mechanical applications, and enables heteroepitaxial growth of cBN films. The etching of the cBN films is preferably carried out by applying a negative-bias in a hydrogen- / argon-based plasma. Alternatively, etching can be conducted by using any chemically reactive environment in synergy with either ion bombardment in plasma or ion beams applied to the cBN films.

Output compensator for a regulatorUS patent number: 8169201

Inventors: Professor Henry Chung, Department of Electronic Engineering

Mr Yan Wai To, ex-CityU staff

The new dynamic output compensator described in this patent is capable of improving the dynamic response of a voltage or current regulator, whose main use is to maintain constant voltage levels. The compensator senses an output signal at a passive component at an output of the regulator, generating a ripple compensating signal. The output compensator does not require redesigning of the power conversion stage or control stage of the regulator, but only requires simple circuit connection of the compensator circuit to the output stage of the regulator. Another strength of this novel technology is that the compensator circuit for generating the compensating signal does not have to process the whole of the output load power of the regulator.

Solar heat absorbing windowChina patent number: ZL201010183327.9Inventors: Dr Chow Tin-tai, Division of Building Science and

Technology

A typical solar heat absorbing window usually works with a ventilating air stream and rotating window frame for reducing air-conditioning load in summer and providing space heating in winter. By replacing the airflow with liquid flow, the solar heat absorption capability can be much improved because of the higher heat-carrying capacity and better heat transfer rate as a result. In this invention, the liquid-to-water heat exchanger and its associated liquid tubings are secured in the window frame, and therefore the buoyancy-induced working circuit is compact. No pumping is required and the liquid circulation rate is self-regulated. The feed water circuit is wall-concealed as in usual circumstances. The window can serve as a water heating device throughout the year.
