PolyU research unveils mechanoelectrical perception in sea urchin spines, empowering next-generation biomimetic sensors

Sea urchin spines are not only for defence—they also act as natural sensors. A research team led by Prof. WANG Zuankai, Associate Vice President (Research and Innovation), Dean of Graduate School, Kuok Group Professor in Nature-Inspired Engineering and Chair Professor of the Department of Mechanical Engineering of The Hong Kong Polytechnic University (PolyU), together with scholars from City University of Hong Kong (CityU) and Huazhong University of Science and Technology (HUST), has discovered the mechanoelectrical perception in sea urchin spines, originating in their gradient porous structure, that allows the spines to instantly detect water flow. Using 3D printing, the team has replicated this structure and developed a bionic metamaterial sensor, which holds promise for breakthroughs in sensing technology. This innovation will drive the advancement of deep-sea technology such as marine monitoring and underwater infrastructure management, and can be extended to other emerging fields like brain-computer interfacing and aerospace. The research team found that, in the long-spined sea urchin (Diadema setosum), when a seawater droplet strikes the tip of a spine, the spine rotates rapidly within a second. Electrical measurements revealed that the droplet simulation produced a voltage of about 100 millivolts inside the spine; when the spine is immersed in water, water flow stimulation triggers a voltage of several tens of millivolts. This mechanoelectrical perception was observed even in dead spines, indicating that the mechanism is unrelated to biological cells. This response originates from the stereom structure of the spine—the porous internal skeleton composed of pores with varying sizes and distributions. These pores exhibit a gradual gradient along the spine from the base to the tip: larger pores and lower solid density at the base, and smaller pores and higher solid density at the tip, forming a bicontinuous gradient porous structure. As water flows through the porous structure, solid-liquid interfacial interaction occurs and the flow exerts shear force on the electric double layer, inducing the separation and redistribution of interfacial charge, which generates a voltage difference. The gradient structure intensifies the interaction between water flow and pore surfaces, resulting in a stronger voltage difference and enhancing the spine’s sensing capabilities. Inspired by these findings, the researchers used vat photopolymerisation 3D printing to create artificial samples from polymer and ceramic materials that resemble the spine’s stereom. Experiments showed that the spine-mimicking design produce a voltage output about three times higher and an amplitude about eight times greater than non-gradient designs under water flow stimulation, demonstrating that the key to the mechanoelectrical perception lies in the structure rather than the material. They also constructed a bionic 3D metamaterial mechanoreceptor that is designed in a 3 × 3 array with each unit made of gradient porous material. This mechanoreceptor can record electrical signals in real time underwater and precisely locate the position of water flow impact, without the need for additional electricity. The team’s bionic 3D metamaterial mechanoreceptor is designed in a 3 × 3 array, with each unit made of gradient porous material. It can record voltage signals in real time underwater and precisely locate the position of water flow impact, without the need for additional electricity. The research team points out that the gradient porous structure in sea urchin spines enhances signal transmission, thereby improving the precision and sensitivity of the mechanoreceptor. By replicating this structure in different materials, it is possible to extend its application beyond water flow sensing to various types of signals, including those measuring pressure, vibration and electromagnetic waves. This will inspire sensing technologies in multiple fields, such as in relation to its use in brain-computer interfaces to enhance the sensing of brainwaves and neural signals, with tremendous application potential. Prof. Wang Zuankai said, “Compared to traditional mechanoreceptors, our design excels in manufacturability, structural design flexibility, material versatility, geometric and performance control, and real-time underwater self-sensing. Leveraging gradients of porous materials and 3D printing technologies, we aspire to produce more nature-inspired metamaterial sensors with a range of materials, pore sizes and surface features that support potential applications in many fields.” At the forefront of nature-inspired science and engineering research, Prof. Wang’s team has also invented various new materials, including lotus leaf-inspired self-cleaning surfaces capable of rapid water repellency, Araucaria leaves-inspired surfaces that enable self-propelled liquid transport, and anti-icing structures that achieve spontaneous ejection of freezing droplets by replicating the biological mechanism of spore shooting in fungi. He envisions that their research will open up new avenues for the development of nature-inspired materials. “For natural porous materials, mechanical properties such as strength may not be the primary function, but rather a by-product of complex biomineralisation. Uncovering previously unknown mechanisms that lie beyond a material’s traditionally recognised function helps us to more comprehensively understand and fully utilise these natural resources. This is crucial for advancing biomimetic research,” he added. This joint research was co-led by Prof. LU Jian from CityU, and Prof. YAN Chunze and Prof. SU Bin from HUST. The study findings have been published in the international journal Nature.   ***END***

PolyU launches next-generation ophthalmic AI clinical co-pilot system, driving innovation in clinical-grade intelligent decision support platforms

With the accelerating trend of population ageing and a growing shortage of specialist doctors, enhancing the efficiency and consistency of ophthalmic diagnosis has become a critical challenge for global healthcare systems. A research team of The Hong Kong Polytechnic University (PolyU) has launched the development of a next-generation clinical-grade ophthalmic artificial intelligence (AI) co-pilot system “EyeAgent 2.0”, aiming to construct an intelligent decision support platform with advanced clinical reasoning capabilities to assist doctors in disease diagnostic analysis, treatment planning and follow-up management, thereby improving the quality and efficiency of clinical judgments. The PolyU team previously developed the “EyeAgent 1.0” prototype system, capable of integrating multimodal medical data including clinical text and images, to provide diagnostic assistance. Pilot testing in hospitals across Hong Kong and Chinese mainland yielded positive clinical feedback. Leveraging this, the team is now developing “EyeAgent 2.0”. The new system is being developed around a domain-specific foundation model trained on large-scale, real-world multimodal electronic medical data from leading ophthalmic centres across different regions. It will integrate fundus imaging, optical coherence tomography, angiography and clinical text data. The system will also simulate actual clinical workflows, including data integration, differential diagnosis, treatment planning, and disease progression prediction through a multi-agent collaborative framework, realising the goal of upgrading from one-time image analysis towards continuous decision support throughout the course of disease. Based on current model validation and prototype testing results, the team anticipates that when fully developed the system, will significantly enhance diagnostic consistency and efficiency, while reducing the time doctors spend on case organisation and documentation. This will help alleviate work pressure in high-load clinical environments. The system’s design emphasises human-AI collaboration, with AI serving as an auxiliary tool for enhancing data integration and analytical capabilities while all final clinical decisions remain doctor-led. Prof. HE Mingguang, Chair Professor of Experimental Ophthalmology and Henry G. Leong Professor in Elderly Vision Health of the School of Optometry, and Director of Research Centre for SHARP Vision, who leads the research, said, “We will continue to incorporate into the system real-world clinical data from diverse regions for training and validation, further optimising reasoning performance and stability. Our goal is to develop the system into a ‘Software as a Medical Device’ compliant with regulatory standards, with plans to progressively advance registration and deployment efforts following completion of clinical validation.” He added that the project had applied for relevant government innovation and technology funding. The team plans to complete system development and validation within the next two years, followed by productisation and commercialisation. The system will pilot first in the Hong Kong market before expanding to the Guangdong-Hong Kong-Macao Greater Bay Area, Chinese mainland and overseas markets. Prof. Christopher CHAO, Senior Vice President (Research and Innovation) of PolyU, stated, “PolyU is actively promoting interdisciplinary innovation in AI and healthcare, striving to translate research outcomes into applications with social value. The development of ‘EyeAgent 2.0’ demonstrates the University’s substantial expertise in integrating AI, data science and clinical specialities. It also serves to enhance Hong Kong’s international competitiveness in medical AI.” The system is intended to adopt a hybrid business model combining annual subscriptions with usage-based charges and will enable flexible deployment tailored to diverse hospital information system architectures. The team aims to foster a trustworthy, standardised and sustainable medical AI ecosystem through continuous technological refinement and clinical collaboration, thereby enhancing regional and global ophthalmic healthcare standards. Looking ahead, PolyU will remain guided by societal needs, deepening the integration of AI with clinical medicine and delivering more efficient, higher quality and more sustainable solutions for healthcare systems through sustained research and development alongside institutional capacity building. ***END***

PolyU develops third-generation intelligent in-situ laser melt pool monitoring technology, deepening industry-academia-research integration to empower advanced manufacturing in Greater Bay Area

A research team at The Hong Kong Polytechnic University (PolyU) has developed “IntraSpect™”, a third-generation intelligent in-situ laser melt pool monitoring technology that marks a breakthrough in high-end precision manufacturing. During welding, high-energy heat sources melt metal to form a micro-scale molten zone known as the melt pool. Its internal condition directly affects welding quality, yet conventional technologies are unable to monitor it in real time during processing. By combining Optical Coherence Tomography with a multi-modal artificial intelligence engine, IntraSpect™ creates an “Industrial Eye” capable of monitoring the melt pool’s internal condition in real time with micron-level precision, capturing three-dimensional morphological changes during welding to address the long-standing industry challenge of welding defects at source. The project has established partnerships with multiple industry leaders in the Greater Bay Area and is advancing commercialisation, with potential applications extending to medical devices, aviation, aerospace and other sectors demanding exceptionally high welding quality. The IntraSpect™ project is led by Prof. H.C. MAN, Dean of the Faculty of Engineering, Cheng Yick-chi Chair Professor in Manufacturing Engineering and Chair Professor of Materials Engineering; and Prof. Xiewen WEN, Assistant Professor of the Department of Industrial and Systems Engineering. Prof. Man has devoted forty years to the field of high-power laser welding, accumulating extensive industry collaboration experience and a deep understanding of industry pain points and practical needs. Prof. Wen specialises in precision optical instrument design and micro-scale dynamic capture technology. Their interdisciplinary collaboration and complementary expertise have ensured that the development of IntraSpect™ has been closely aligned with industrial application scenarios from inception. Prof. H.C. Man said, “Conventional welding monitoring relies primarily on surface observation or post-process inspection, making it difficult to capture the melt pool’s internal condition in real time during processing. The consequences range from product scrapping and economic losses to, at worst, safety incidents. IntraSpect™ intervenes at the source, identifying and correcting defects at an early stage. This transforms reactive post-process inspection into proactive prevention, dramatically reducing scrap rates while significantly enhancing production efficiency and product reliability.” Prof. Xiewen Wen explained, “IntraSpect™ is like equipping welding machinery with an ‘Industrial Eye’. Within one-millionth of a second, it can penetrate the arc flash, metal vapour and spatter generated during welding to directly measure the three-dimensional depth and morphology inside the melt pool, achieving micron-level, real-time navigation. This enables the machine to self-correct during welding, achieving closed-loop process control.” Testing has validated that the IntraSpect™ system’s detection data deviates by less than two percent from destructive testing results, with technical specifications reaching internationally leading standards. Compared to similar imported products, the system costs approximately half as much, with investment recoverable in less than one year. The team estimates that this technology can replace up to 70% of destructive testing processes, substantially saving material and time costs while achieving 100% comprehensive monitoring and establishing a complete quality traceability record for every weld. IntraSpect™ will initially focus on precision welding processes for new energy vehicle batteries and 3C electronic products such as smartphones. The team is collaborating with industry partners on pilot testing to transform the technology into practical industrial solutions. In the long term, the technology has additional potential for extension to medical devices, aviation, aerospace and other sectors with extremely stringent welding quality requirements. Prof. Christopher CHAO, Senior Vice President (Research and Innovation) of PolyU, remarked, “IntraSpect™ fully demonstrates PolyU’s unique strengths and potential in deep industry-academia-research integration. We are committed not only to achieving original breakthroughs in frontier technologies, but also to translating research outcomes from campus to industry for the benefit of society. The National 15th Five-Year Plan continues to emphasise the development of new quality productive forces, and intelligent manufacturing is the core engine driving industrial upgrading through technological innovation. PolyU will continue to actively align with national strategies and the HKSAR Government’s new industrialisation policies, contributing to the upgrading of high-end manufacturing in the Guangdong-Hong Kong-Macao Greater Bay Area and further consolidating Hong Kong’s unique position as an international innovation and technology hub.” The team aspires to combine Hong Kong’s research strengths with the Greater Bay Area’s industrial ecosystem to build a safer, more efficient and more intelligent high-end manufacturing system for the Nation, while injecting new momentum into Hong Kong’s high-quality economic development.   ***END***

In July and August this year, PolyU will host the International Summer School (ISS) 2026 for undergraduate students as well as the Summer Institute (SI) 2026 for high-school students. These programmes welcome students from around the world to experience PolyU’s excellent learning and teaching culture as a global top 100 university, alongside a wide range of local tours and cultural experiences. This year, the ISS is launching a seven-day PolyU Summer Discovery for the first time, while the SI has further expanded its range of subjects to provide students with fresh and enriching learning experience. Now in its tenth year, the ISS is a five-week programme designed for undergraduate students. It features three thematic learning tracks that align closely with global development trends: “Chinese Language, Culture and Society”, “Science, Technology and Creative Design” and “Innovation, Entrepreneurship and Global Impact”. The PolyU Department of Applied Physics will, for the first time, offer a course on astronomy, covering basic knowledge of celestial motion, light and matter, the solar system, stellar evolution and the large-scale structure of the universe, as well as methods of observing astronomical phenomena. There will also be other courses such as multilingual societies in Hong Kong, smart wearables and smart living, and renewable energy for a sustainable world. The ISS has been well-received by students worldwide since its launch. Daisy DAI, a participant from the Chinese Mainland, said, “The ISS has broadened my horizons. Interacting with students from around the globe has been immensely rewarding. I highly recommend it to anyone looking for a unique and fulfilling summer experience.” Sofia FELLINGER, a participant from Germany, said, “The courses here are well-organised, making it easy to access information and connect with others. This fulfilling and meaningful learning experience has motivated me to consider pursuing further studies at PolyU in the future.” The newly introduced seven-day PolyU Summer Discovery offers students in-depth experience of local culture and campus life, free from academic pressure. Activities include guided campus tours, local cultural explorations, workshops on intangible cultural heritage handicrafts and international networking events. These will enable students to gain a comprehensive understanding of PolyU, be introduced to Hong Kong’s multiculturalism and expand their intercultural exchange networks. PolyU ISS 2026 and PolyU Summer Discovery are now accepting undergraduate student applications until 23 March. For details, please visit: https://www.polyu.edu.hk/summerschool/. The SI welcomes high-school students from around the globe, bringing together students from diverse cultural backgrounds to experience campus life at PolyU. During the five-day residential camp, students will live in the University’s student halls and take part in day-long attachment activities organised by PolyU faculties and schools, as well as visits to local companies and organisations. These experiences aim to inspire them to learn more about different academic disciplines and related career prospects, better preparing them for future studies. The SI will offer an expanded selection of subjects this year. During the five-day programme, students can choose from 16 credit-bearing or non-credit-bearing subjects in areas such as business, applied social sciences, computing and artificial intelligence, engineering, construction, science, humanities, design, fashion and textiles. This allows them to explore their interests in depth and plan their future study pathways. Students who successfully complete the credit-bearing subjects may apply for credit transfer upon later admission to PolyU, subject to prevailing academic regulations. The PolyU SI 2026 is now open for applications from high-school students. Deadline for non-local applicants is 31 March, and for local applicants is 31 May.
