The Defocus Incorporated Multiple Segments (DIMS) Spectacle Lens for Myopia Control was awarded the Grand Prize, Grand Award and Gold Medal with the Congratulations of Jury. Other exhibition projects from Hong Kong were also awarded with a total of 25 gold medals with the congratulations of the jury, 47 gold medals and 26 silver medals.
The Hong Kong Polytechnic University (PolyU) has won 9
prizes at the 46th International
Exhibition of Inventions of Geneva. Held from 11 to 15 April, the
Exhibition has attracted 823 exhibitors from 40 countries/regions, showcasing
around 1,000 new products. Under the patronage of the Swiss Federal Government,
the State and the City of Geneva as well as the World Intellectual Property
Organization, it is the biggest event of its kind globally.
According to the press
release by PolyU, these breakthroughs not only expand the boundaries of
knowledge, but also enhance the well-being of our society on different fronts
as they cover a wide range of application areas.
"PolyU is committed to making the world a better place
through research, innovation and knowledge transfer," remarked Dr Miranda
Lou, Executive Vice President of PolyU.
"These awards manifest the fruition of the tireless
efforts of our research experts. We take great pride in their
contribution in technological advancement, which doubtlessly deserves
international recognition,” she added.
Among these breakthroughs, the Defocus Incorporated Multiple
Segments (DIMS) Spectacle Lens for Myopia Control was awarded the Grand Prize, Grand
Award and Gold Medal with the Congratulations of Jury. The Grand Prize is
considered the top honour of the event.
According to the press
release by the International Exhibition of Inventions of Geneva, the
multi-segment spectacle lens for myopia control were developed by Professor
Carly Sy Lam and Professor Chi Ho To. The lenses comprising several microlens
segments that constantly defocus the short-sighted vision of myopia sufferers,
enabling them to see clearly. The device has been shown to slow the progression
of myopia in children by 60%, and even stopped it altogether in 20% of the
Myopia affects countless people around the world, but in
some regions it almost endemic. In several Asian countries, nearly 80% of the
population are short-sighted. The glasses developed by Prof Sy Lam and Prof To
are composed of hundreds of micro-lenses whose action employs the natural
homeostatic mechanism that regulates the size of the eyeball based on the
physical characteristics of optical input. The clinical results indicate a
spectacular slowing of the disease. Apart from reducing the myopia itself, the
DIMS glasses also significantly reduce the overall risk of associated diseases,
such as retinal detachment and glaucoma.
Other winning projects from PolyU at the Exhibition are:
Intelligent 3D Stereoscopic Imaging
System on Plenoptic Camera
The innovation won
Gold Medal with the Congratulations of Jury. Led by Ir Prof Wing Bun Lee
from the Department of Industrial and Systems Engineering, the intelligent 3D imaging system
with internal reflection unit can capture multiple angles of an object at the
same time, generating a high-quality 3D image or video with depth map
information after image processing.
Scalable All-Textile Energy Harvesters
for Electric Power Generation
The project won Gold
Medal with the Congratulations of Jury. Led by Dr Bingang Xu from the Institute
of Textiles and Clothing, this novel textile can harvest ambient mechanical
energy for electric power generation.
The textile is super-flexible, tailorable, washable and can
be fabricated by existing machines .It can be used as wearable power sources
for portable and wearable devices, e.g. hearing aid, fitness tracker, wearable
Automated System for Surface Pitting
Analysis on Airplane Jet Engine
The project led by
Dr Stephen O’Brien from Aviation Services Research Centre (ASRC) won Gold Medal.
Pitting is surface defect found on critical jet engine components of complex
shapes and different sizes. It is currently detected by naked-eye inspection.
Such task takes up significant man-hours and embodies errors in accuracy and
The newly-developed automated system by PolyU’s ASRC employs
robotics, artificial intelligence (AI) and deep learning, image processing, 3D scanning,
optical metrology, and non-destructive testing technologies to identify and
measure corrosive pitting such that precise information such as pitting
position, depth and diameter can be obtained.
This system can be used together with the automated surface
defect removal system developed by ASRC. When a surface defect is identified,
the removal system may execute artisan level workmanship to repair the defects.
This enables automation of jet engine maintenance procedures and significantly
shortens the process from the 4-hour manual method to 1.5 hours, enhancing the
quality, reliability and accuracy of work; and cuts down operation costs. It
can thus substantially reduce the turnover time for aircraft maintenance and
airplane turnaround time.
In future, ASRC will apply deep learning defect detection in
other areas such as Non-Destructive Testing (NDT) images or fuselage inspection
to further realize automation in aircraft maintenance. In the perceptive of Big
Data and Industry 4.0, this kind of automation enables information collection
and pattern analysis of defects, leading to better engine part design in
eNightLog – Night-time Monitoring
System for Caring Elderly with Dementia
The project led by Ir
Prof Yongping Zheng from Department of Biomedical Engineering won the Gold
Medal. Equipped with event sequence tracking, different kinds of remote sensing
and imaging technologies, this system performs intelligent night-time
monitoring of dementia patients in a non-restraint approach. In case of unusual
incident, the system will send an alert message to the caregiver immediately,
expediting the incident handling process. PolyU will install over 100 units of
eNightlog in local elderly health centres in Hong Kong.
Micro-embossing Equipment for Precision
The project led by Dr
Lihua Li from the Department of Industrial and Systems Engineering won the Gold Medal. The novel
micro-embossing equipment with graphite-like carbon film can produce
micron-level micro-structural optical components in glass using self-developed
heating technology and innovative mould design. The equipment enables rapid and
accurate impression of small aspheric lens and fine optical microstructures
such as micro-lens array.
Sprayable Smart Sensing Network Coating
for Structural Health Monitoring
This project led by
Prof Zhongqing Su, Department of Mechanical Engineering, won the Gold Medal. The
new breed of nanocomposites can be sprayed directly onto engineering
structures, forming smart sensing network coatings for in-situ structural
health monitoring and damage detection purposes. Due to its low fabrication
cost, large quantities of sensors can be deployed in a sensor network, paving
the way for a new era of structural health monitoring.
On 13 April, the Hong Kong Economic and Trade Office in
Berlin (HKETO Berlin), together with the Hong Kong Federation of Invention and
Innovation (HKFII), hosted a reception at the 46th International Exhibition of
Inventions Geneva to support the exhibitors from Hong Kong.
Representing a city with strong focus on innovation, HKFII brought a delegation
of more than 100 people from Hong Kong, and showcased a total of 98 projects in
the exhibition. These projects ranged from microbial technology that turns food
waste to biodegradable plastic bags to lip password for access control.
Other than PolyU, other exhibition projects from Hong Kong
were also awarded with a total of 25 gold medals with the congratulations of
the jury, 47 gold medals and 26 silver medals.
"Hong Kong has strong research and development capabilities and talent,
excellent technological infrastructure, world-class universities and academics,
a sound legal system and a robust intellectual property protection
regime," highlighted by the Director of the HKETO Berlin, Ms Betty Ho, at
Given Hong Kong's favourable location in the
heart of the Guangdong-Hong Kong-Macao Bay Area, Ms Ho added that the city
would continue to step up collaboration in innovation and technology with the
talent pools from other economies and capture the unprecedented opportunities
