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

“YOU BRING CHARM TO THE WORLD — The 18th Global Chinese Awards” Concludes in Beijing
At this year’s awards ceremony, Academician Zhang Boli of the Chinese Academy of Engineering received the Global Chinese Lifetime Achievement Award, while actress Sylvia Chang received the Global Chinese Special Tribute Award. Academician Pan Jianwei of the Chinese Academy of Sciences, Lu Chaoyang, Chair Professor at the University of Science and Technology of China, picture-book illustrator Cai Gao, Chinese freestyle skier Xu Mengtao, Gao Du, professor at the Beijing Dance Academy, and actress Xin Zhilei received the Global Chinese Award.
In his speech, Xu Wei, Chairman of the Board and CEO of Phoenix TV, said: “Each generation of Chinese people has its own responsibilities. The older generation worked hard with their roots in their homeland, while the younger generation embraces innovation and the world, becoming connectors between different cultures.” Phoenix TV will continue to serve as an on-the-ground reporter of major global events, an international storyteller of Chinese culture, and a platform builder for international exchange, enabling audiences around the world to see more of the vibrant and diverse achievements of Chinese people.
The tribute section of the ceremony opened with an immersive children’s picture-book theatrical performance based on classic works including The Story of the Peach Blossom Spring and Bao’er. Both works were created by Cai Gao, who received the Hans Christian Andersen Award for Illustration in April this year. During the ceremony, the host recalled the children’s song Cai sang at the Andersen Award ceremony, prompting her to smile and sing “The Cuckoo” once again.
Upon receiving the Global Chinese Award, Cai Gao said that the splendid and outstanding artistic heritage of China has been a source of inspiration for her work, and that she has a deep love for the culture of this land. Seeing so many Chinese people achieve remarkable accomplishments in different fields has also given her spiritual strength. Quoting the phrase, “As long as life goes on, the struggle continues,” she encouraged herself to keep creating with passion and curiosity. “Life and creation require dedication and perseverance. I am willing to devote myself to them, as I always have.”
Joining the ceremony via video link, Lu Chaoyang shared his joy and said that the honor belongs to all Chinese researchers who have climbed, generation after generation, along the long and steep road of quantum science.

“If the dance steps of a people disappear, that chapter of history will also lose its voice.” Over the past 50 years, Gao Du and his team have traveled across more than 20 provinces and autonomous regions throughout China, venturing deep into remote mountains and visiting people’s courtyards and fireside gatherings. They learned from local communities dances that had no names, no stages and sometimes not even an audience, devoting themselves to the creation of the Chenxiang series.
Gao Du said he would continue dancing, both in the classroom and on larger stages, bringing folk dance traditions rooted in the land to the world and fostering dialogue among different cultures, so that the world can see the beauty of the East.
Wu Qingcai, Deputy Editor-in-Chief of China News Service, presented Xu Mengtao with the Global Chinese Award. Xu shared that August 13, 2026, marked exactly 24 years since she began competing in the aerials discipline of snow sports. She hopes everyone can create something extraordinary through perseverance and dedication. “In the future, I will once again stand on the starting platform and set off again. See you again at the summit.”
As one of the creators of the song Tomorrow Will Be Better, Sylvia Chang said that she and fellow Chinese-language singers hope to use music to build a bridge for peaceful communication. She expressed gratitude for being able to continue pursuing a career she loves and for having a wonderful family. “I hope to share this gratitude and these blessings with everyone.”
At the ceremony, the host recounted the eight-character motto that Academician Zhang Boli has followed throughout his life: “Uphold virtue to broaden its influence; use medical skills to serve humanity.” Now approaching 80, Zhang Boli continues to see patients at a clinic every week. When patients have difficulty walking, he takes the initiative to go downstairs and see them in their cars.
Zhang Boli said that the concepts of traditional Chinese medicine—including health preservation, wellness and preventive treatment—represent one of the best practices of “proactive health management.” Looking to the future with the compassion of a physician, he said: “Let traditional Chinese medicine benefit Chinese people around the world, and let traditional Chinese medicine benefit people everywhere. The world will be healthier because of traditional Chinese medicine.”
It is reported that the “YOU BRING CHARM TO THE WORLD — Global Chinese Awards” was initiated by Phoenix Media Group in collaboration with China News Service and numerous Chinese-language media organizations in China and overseas. Together, they select and honor outstanding Chinese people who have achieved excellence and made a global impact in different fields, helping to amplify the achievements of exceptional Chinese individuals and inspire more generations to come.

NINGJI Takes Centre Stage at KLCC, Strengthening Its Position as a Benchmark for Southeast Asian Expansion Through Five Key Localization Strategies
During the event, Dato’ Liew Bin, President of the Malaysia Retail Chain Association (MRCA), visited the NINGJI booth. The two parties exchanged views on NINGJI’s brand development, product offerings and expansion plans in the Malaysian market.
Backed by a proven store model and a comprehensive overseas support system, NINGJI attracted strong interest from high-quality investors throughout the event. Over the three-day exhibition, the brand successfully signed agreements for 20 new stores, bringing its total number of contracted stores in Malaysia to 82. Potential partners across multiple regions also expressed interest in establishing strategic partnerships with the brand, demonstrating NINGJI’s growing appeal in international markets.
Through product tastings and immersive interactive experiences, NINGJI also strengthened its connection with local consumers. The event generated several thousand new member registrations, building a valuable base of first-party customer data for future localized marketing initiatives.
As one of China’s leading new-style tea brands, NINGJI began its global expansion at the end of 2024. To date, the brand has signed agreements for more than 150 overseas stores across Malaysia, Singapore, Australia, New Zealand, the United States, Vietnam, Thailand, the Philippines, Indonesia, Cambodia and other markets.
In Malaysia, NINGJI currently operates nine stores, with more than ten additional locations in development. Its network is steadily expanding across key commercial districts, while the brand continues to strengthen its influence throughout Southeast Asia.
Five Localization Strategies for Malaysia, Ningji’s Anchor Overseas Market
With its young and diverse population, well-established food and beverage sector, and year-round tropical climate, Malaysia provides highly favourable conditions for refreshing fresh fruit and lemon tea beverages.
Against this backdrop, NINGJI has identified Malaysia as one of its core overseas markets and is systematically advancing its localization strategy across five key areas: store network development, supply chain infrastructure, product portfolio, organizational capabilities and brand marketing.
Expanding Across Key Commercial Districts and Empowering Every Store Through Digital Intelligence
NINGJI will use Kuala Lumpur and Johor Bahru as two strategic hubs, drawing on its proven store operating experience to establish a more refined system for site evaluation, store development and project management.
The brand has built strong digital capabilities, including an end-to-end digital system covering site selection and daily operations, as well as four AI-powered agents that provide franchise partners with integrated, data-driven support.
While steadily expanding its store network and market coverage, NINGJI remains equally focused on store-level operating quality and long-term profitability. The brand aims to build a high-quality retail network that reaches a diverse range of commercial districts and serves a broad customer base.
Strengthening the Local Supply Chain with a Forward Warehouse in Malaysia
Supply chain capability is the lifeline of any new-style tea brand. In China, NINGJI operates seven warehousing centres, manages more than 2,000 mu of lemon orchards. These capabilities have laid a solid foundation for the brand’s continued expansion.
NINGJI believes that genuine localization means combining the capabilities of its headquarters with local market resources. The brand plans to establish a forward warehouse in Malaysia by the end of the year.
Once operational, the facility will enable efficient “T+1” delivery across Malaysia’s key regions, helping stores reduce the risk of stock shortages while significantly lowering the amount of capital franchise partners need to commit to inventory. It will also provide strong logistical support for the continued expansion of NINGJI’s store network.
Balancing Classics and Innovation to Create Products for Local Tastes
NINGJI’s menu centres on fresh fruit lemon beverages paired with whole-leaf tea. Its use of fresh ingredients and made-to-order hand-shaken preparation gives the brand strong cross-cultural appeal and makes its products naturally suited to international markets.
In Malaysia, NINGJI has chosen not to simply replicate its existing menu. Instead, the brand has adopted a “signature products for customer acquisition plus localized innovation” strategy.
On the one hand, proven bestsellers led by Superior Taste Award-winning YaShiXiang Lemon Tea have launched in Malaysian, on the other hand, NINGJI continues to refine its ingredient transportation and storage solutions while developing products tailored to local flavour preferences and market conditions.
In addition to its consistently popular core products, NINGJI has already launched its new pineapple series in Malaysia. The well-received Lemon Milk Series is scheduled to make its official debut in October.
Moving forward, the brand will maintain a quarterly product launch cycle and continue using localized flavours and product innovation to energize the market.
Establishing a Regional Headquarters and Building a Professional Local Team
Local talent is essential for any brand seeking to establish deep and lasting roots in an overseas market.
NINGJI has already assembled a professional team in Malaysia covering local site selection, store development and operational management, and the team continues to grow. This will further enhance the brand’s responsiveness throughout the entire store development journey, from preliminary site selection and opening preparations to daily operations.
NINGJI also plans to establish a regional headquarters in Malaysia and further strengthen its partner support system across staff training, marketing and operational management.
By working alongside local franchise partners who share its commitment to long-term growth, NINGJI aims to expand the market and create greater opportunities together.
Communicating Across Cultures Through Localized Design and Marketing
NINGJI aims to become part of the everyday lives of Malaysian consumers.
In terms of visual presentation, the brand retains its signature yellow and green colour palette while incorporating local aesthetic preferences. Through its “one store, one design” approach, NINGJI creates open and comfortable social spaces tailored to different locations and communities.
From a marketing perspective, the brand will continue to engage with local festivals and cultural trends while collaborating with Malaysian KOLs and KOCs. By connecting social media content with offline experiences, NINGJI seeks to build an emotional relationship with consumers that goes beyond the products themselves and genuinely become part of the local lifestyle.
During its Kuala Lumpur market launch, for example, NINGJI invited Elyn Leong, a Malaysian member of the girl group Gen1es, to serve as “Store Manager for a Day.” Supported by extensive social media promotion, the “Lemon Tea for the Whole City” campaign generated more than one million views and tens of thousands of user-generated interactions across Xiaohongshu, Instagram and Facebook.
Committed to Long-Term Growth, NINGJI Creates Multidimensional Cultural Dialogue Through Localization
NINGJI believes that true globalization is not about simply replicating an existing model. It is a process of deep integration, continuous learning and ongoing refinement.
The brand continues to adapt its products, operations and communications to the consumer characteristics of each market, moving beyond simply “going global” towards becoming genuinely embedded in local communities.
A representative of NINGJI’s overseas business division said:
“Malaysia has a young, diverse and dynamic consumer market and is an important part of NINGJI’s international growth strategy. In the second half of 2026, while steadily expanding our store network, we will further advance the localization of our products, operations and brand communications. We will also continue strengthening our local team and supply chain infrastructure while building long-term relationships with more partners who understand the Malaysian market.”
Looking ahead, NINGJI will continue to build on its product strength and in-store experience while exploring diverse forms of collaboration with local business organizations, content creators and industry partners.
Starting with a cup of fresh fruit lemon tea, NINGJI aims not only to become part of Malaysian consumers’ everyday lives, but also to work alongside local partners to unlock new growth opportunities in the freshly prepared beverage market.
