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.

Under the agreement, ACx and ALMI will share methodologies and best practices in mall asset operations, leasing strategy and project development to improve operational efficiency, enhance customer experience and maximize the long-term value of CP AXTRA’s land and assets, initially focusing on seven key stores of Makro. The parties will also explore future investment opportunities related to mall and asset development in Thailand, alongside collaborative initiatives for the development of new sites and the redevelopment of existing CP AXTRA sites across the country. This is the third agreement signed between CP AXTRA and Ayala, underscoring the strong partnership and continued collaboration between the two groups, following their previous agreements to operate Makro in the Philippines and expand regional business opportunities.
“This agreement with Ayala allows us to combine CP AXTRA’s deep understanding of the Thai retail market with Ayala’s decades of experience in developing and leasing shopping mall spaces. By applying proven methodologies to our Makro mall, we aim to elevate the standards of the retail environment we offer, not only improving the experience for our shoppers and tenants, but also fostering sustainable growth and creating long-term value for our asset and the surrounding community,” said Tanit Chearavanont, Group Chief Wholesale Business Officer, CP AXTRA Public Company Limited.”
“This is another milestone in our growing relationship and collaboration with the CP Group. Through this partnership, we intend to leverage the complementary strengths of two leading conglomerates to create world-class retail and real estate developments across markets. This also marks Ayala’s entry into the Thailand market, giving us a strong opportunity not only to share our expertise, but also to gain valuable insights from one of Southeast Asia’s most dynamic and developed retail markets. More broadly, this partnership aligns with Ayala’s strategy of bringing the best of the world to the Philippines while showcasing the best of the Philippines to the world,” said Mark Uy, Managing Director and Group Head of Strategy and Business Development, Ayala Corporation.
“Makro’s nationwide footprint gives it a meaningful role in the everyday lives of Thai consumers. Our opportunity is to help turn that everyday relevance into places people choose to stay, explore, and return to. By combining CP AXTRA’s market knowledge with Ayala Malls’ experience in curating retail partners, improving customer journeys, and building community-oriented retail destinations, we believe these sites can become stronger platforms for shoppers, merchant partners, and long-term asset growth,” said Mariana Zobel de Ayala, Managing Director and Group Head of Leasing and Hospitality of Ayala Land.
The collaboration brings two complementary strengths together. CP AXTRA is one of ASEAN’s leading wholesale and retail operators, with more than 2,700 Makro and Lotus’s stores. The company is a regional leader in multi-format, omnichannel retail platforms across Southeast Asia and is advancing toward retail-tech company. ALMI, is one of the Philippines’ leading mall operators, managing 34 shopping centers recognized for their strong retail planning, curated tenant mix, and enhanced customer experience across Southeast Asia. With extensive expertise in leasing, mall operations, facility management, and mixed-use development, ALMI is well positioned to support CP AXTRA in maximizing the value and potential of its Makro mall assets in Thailand. Ayala Corporation also brings a broader consumer and enterprise ecosystem that can complement CP AXTRA’s regional retail expansion, while ACx, its consumer retail unit, adds perspective on evolving customer behavior, format innovation, and retail partnerships.
The MoC builds on the two groups’ existing strategic partnership, which began in 2025 with the formation of CP AXTRA AC CORPORATION to operate Makro stores in the Philippines and was expanded to include a wider range of collaborative opportunities. This new agreement deepens that partnership further, marking the first time Ayala will bring its mall development and leasing expertise directly to CP AXTRA’s operations in Thailand.
