The lecture commenced with a warm welcome and a brief introduction of the speaker by Prof. CHEN Qingyan, Director of PAIR. Prof. Zheng kickstarted his presentation by outlining the key driving forces of innovation and technologies. He shared that achieving success in the “from zero to one” and the subsequent “from one to N” innovation stages often come with the inevitable “valley of death” period, which spans over a decade. He then elaborated on how he and his team have spent 20 years of relentless effort overcoming the “valleys of death” in studying structural superlubricity, building a model for talent development, and entering into the next “one-to-N” development phase. Prof. Zheng also shared the key turning points in his academic and research journey and outlined how the X-Institute nurtures interdisciplinary research talents.

A rapidly expanding research area involves the development of routes to shape programmable three-dimensional (3D) structures with feature sizes in the mesoscopic range (that is, between tens of nanometres and hundreds of micrometres). A goal is to establish methods to control the properties of materials systems and the function of devices, through not only static architectures, but also morphable structures and shape-shifting processes. Soft matter equipped with responsive components can switch between designed shapes, but cannot support the types of dynamic morphing capabilities needed to reproduce continuous shape-shifting processes of interest for many applications. Challenges lie in the establishment of 3D assembly/fabrication techniques compatible with wide classes of materials and 3D geometries, and schemes to program target shapes after fabrication.
In this talk, Prof. HUANG Yonggang will introduce a mechanics-guided assembly approach that exploits controlled buckling for constructing complex 3D micro/nanostructures from patterned two-dimensional (2D) micro/nanoscale precursors that can be easily formed using established semiconductor technologies. This approach applies to a very broad set of materials (e.g., semiconductors, polymers, metals, and ceramics) and even their heterogeneous integration, over a wide range of length scales (e.g., from 100 nm to 10 cm). To allow realisation of 3D mesostructures that are capable of qualitative shape reconfiguration, Prof. HUANG devises a loading-path controlled strategy that relies on elastomer platforms deformed in different time sequences to elastically alter the 3D geometries of supported mesostructures via nonlinear buckling. Prof. HUANG will also introduce a recent work on shape programmable soft surface, constructed from a matrix of filamentary metal traces, driven by programmable, distributed electromagnetic forces that follow from the passage of electrical currents in the presence of a static magnetic field. Under the guidance of a mechanics model-based strategy to solve the inverse problem, the surface can morph into a wide range of 3D target shapes and shape-shifting processes. The compatibility of these approaches with the state-of-the-art fabrication/processing techniques, along with the versatile capabilities, allow transformation of diverse existing 2D microsystems into complex configurations, providing unusual design options in the development of novel functional devices.

This video is made by Dr. Pearl Lin and Dr. Clare Fung's project, "Great Case of Marketing in the Hospitality and Tourism Industry." A special thanks to Liu Hao, who provided information and insights for this video. This case discusses how the Chinese tea brand Naixue collaborated with musician Jay Chou's Fantasy album to create a successful marketing campaign. Naixue leveraged Chou's massive fanbase by co-branding with the album, allowing them to use Chou's image and music without the high endorsement fees. They created a "Fantasy Music Universe" virtual space where consumers could access digital products and rewards by purchasing co-branded items. This innovative digital and experiential marketing strategy led to record-breaking sales, enhanced Naixue's brand image, and showcased the power of AI and digital technology in modern marketing. However, the case also highlights the need for brands to balance technological innovation with maintaining brand integrity and transparency to sustain long-term consumer trust.

The seminar commenced with a welcome speech and speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation) of PolyU. This was followed by Prof. Leng’s presentation. He first provided a brief background about shape memory polymers (SMP), pointing out that these smart materials can reversibly change between permanent and temporary shapes in response to changes in external stimuli such as temperature. Next, he gave an overview of the researchers from different scientific research institutions and universities around the world who specialise in SMP research, and the types of SMP materials that HIT researchers focus on. He said that SMP are hard to actuate and their recovery strength and speed are low, and so relevant solutions to these challenges are important for the development of SMP composites (SMPC). Prof. Leng then gave examples demonstrating how SMPC can be prepared through actuation methods involving different stimuli such as heat, electricity, magnetism, radio frequency, solution/water, light, etc. He mentioned that SMPC can be used to prepare various structures for aerospace, smart manufacturing, photoelectric applications, microelectromechanical systems applications, and smart clothing. After that, Prof. Leng introduced 4D printing, a novel additive manufacturing process for producing printed objects that can adaptively change their configurations/properties in response to external stimuli. He mentioned that 4D printing is important for producing a range of SMPC-based materials for biomedical applications. To conclude, Prof. Leng said that SMP research is a fast-growing emerging research field. He anticipated that shape memory smart structures incorporated with sensors, actuators, and controllers, would be widely used in aerospace, civil aviation, automotive, energy and daily life.

The lecture commenced with a welcome speech and speaker introduction by Prof. CHEN Qingyan, Director of PAIR, followed by a presentation by Prof. Cui. He first shared his scientific journey by reminiscing about the old days when he moved abroad to develop an academic career after graduating in China and gradually became a highly successful scientist. Next, he explained the importance of interdisciplinary research and shared how the combination of medical science and engineering enables the development of health technologies such as imaging, keyhole surgery, in vitro diagnostics, in vitro fertilisation, etc. Prof. Cui emphasised that scientists are to “discover” and find out “how a thing happens” whereas engineers are to “create” and “make things happen”. He then gave some advice on how to do well in interdisciplinary research and shared some innovations in microbioreactor and point-of-care testing developed by him and his team which has achieved great success in research commercialisation and made significant contributions to drug discovery and public health. To conclude, Prof. Cui shared that scientific success is based on many factors, including team, facilities, timing, luck, etc., and encouraged the next generation of engineers and scientists to consider a career in biomedical engineering, an exciting and rewarding domain.
Following the lecture, a lively and insightful question-and-answer session was moderated by Ir Prof. ZHANG Ming, Director of the Research Institute for Sports Science and Technology (RISports), Head of the Department of Biomedical Engineering and Chair Professor of Biomechanics. The audience had fruitful discussions with Prof. Cui.

In his presentation, Prof. Brilakis first gave a brief introduction to digital twins (DT), pointing out that DT plays a central role in digital transformation. Next, he elaborated on the application of DT in the construction industry and explained how DT is involved in the planning, design, construction, maintenance and operation processes. He introduced research conducted at the University of Cambridge on inexpensive methods for generating object-oriented infrastructure geometry, detecting, and mapping visible defects on the resulting DT, automatically extracting defect spatial measurements, and sensor and sensor data modelling. Prof. Brilakis also provided examples of how these resulting DT are further exploited in design for manufacturing and assembly (DfMA), mixed-reality-enabled mobile inspection, and proactive asset protection from accidental damage. To conclude, Prof. Brilakis stated that DT, smart materials, data science, and automation & bobotics, constitute important digital assets for driving sustainability, and pointed out the future development directions in these areas.
