BARCELONA, SPAIN – Media OutReach Newswire – 5 March 2026 – Infinix is cementing its status within the premium smartphone segment in a bold new way with NOTE 60 Ultra, its landmark flagship debuting in Barcelona during Mobile World Congress 2026.
Infinix NOTE 60 Ultra Design by Pininfarina
Co-developed with Italian automotive and design legend Pininfarina, NOTE 60 Ultra’s design is driven by an emotion-led aesthetic inspired by super cars. Beneath its bold design lies a fully realized flagship experience, integrating breakthrough in-house innovations with best-in-class partner technologies. A professional-grade 200MP ultra-high-definition imaging system, built-in multi-country satellite communication connectivity, and immersive audio precision-tuned by SOUND BY JBL come together to challenge expectations in the premium segment.
Supercar Design DNA in a Flagship, Shaped by Pininfarina
In the premium segment, the design language is a device’s opening statement. A user’s perception at first glance is shaped by aesthetics, long before a single specification is considered.
Drawing inspiration from the aerodynamic philosophy and pioneering spirit of high-performance sports cars, Infinix, in partnership with Pininfarina, takes a radical departure in sculpting a flagship. What stands out immediately is what’s missing: the camera bump. As premium handsets adopt larger sensors, they often sacrifice form with increasingly protruding camera modules.
True to the sports car heritage, NOTE 60 Ultra introduces a fully integrated, single-body rear: the Aluminum Unibody Design. At the heart of this craftsmanship is the World’s 1st Uni-Chassis Cam Module, formed a single, continuous sheet of CORNING® GORILLA® GLASS VICTUS that virtually conceals the presence of the camera. Much like a supercar sculpted for low-drag, the rear design maintains a smooth, uninterrupted silhouette. This also ensures a natural in-hand feel and unobtrusively slips into any pocket, while reinforcing the phone’s durability and structural integrity.
Paying homage to Italian cultural and racing heritage, NOTE 60 Ultra arrives in four striking colorways: Torino Black, Monza Red, Amalfi Blue, and Roma Silver. Each hue draws inspiration from the most iconic scenes and legends of Italy’s motorsport and cultural history, capturing the spirit of speed, lifestyle, and emotional beauty.
Just as a supercar announces its ignition through sound and light, NOTE 60 Ultra mirrors the ritual. A Floating Taillight signature spans the rear, illuminating as the device powers on. And as a final nod to automotive heritage, NOTE 60 Ultra features an Active Matrix Display reminiscent of a supercar dashboard at startup. Concealed within the rear surface, the hidden display lights up to reveal notifications, expressive icons, or a pixel-style virtual companion.
Dual Flagship Cameras for Detail, Zoom, and True-to-Life Imaging
Although discreet at first glance, Infinix makes no concessions on camera performance and earmarks a new era for Infinix’s imaging capability. Delivering performance on par with industry-leading standards, Infinix’s Dual Flagship Imaging Architecture marks several brand-first breakthroughs and improvements across three dimensions, reinforcing its position as a signature offering.
Under the hood, it’s clear that NOTE 60 Ultra refuses to settle for less. Discreetly integrated within the Uni-Chassis Cam Module is a powerful triple-camera array. Anchored by a next-generation 200MP Samsung ISOCELL HPE sensor, NOTE 60 Ultra delivers ultra-high-definition clarity. And ensuring flagship-grade versatility across focal lengths, the phone is complemented by a 50MP Samsung ISOCELL JN5 periscope telephoto lens and a 112° ultra-wide lens.
However, hardware alone does not define the full experience. For the first time, Infinix supports the XDR display standard with Ultra HDR Capture. Powered by a proprietary XDR Image Engine, Infinix’s advanced system delivers a superior dynamic range, ideal for true-to-life photos of bright lights at night or breathtaking sunset scenes.
The result is exceptional resolution that sets a higher bar for precise framing in daylight or after dark, while faithfully preserving details often lost in standard photography. Whether exploring daytime cityscapes or distant horizons, NOTE 60 Ultra excels with its advanced optical‑to‑digital zoom performance. Crisp, detailed shots are captured across a versatile zoom range, from a 2× optical crop and native 3.5× optical zoom to a 7× lossless digital zoom, extending up to 100× for extreme distances.

HONG KONG SAR – Media OutReach Newswire – 5 March 2026 – The Town Planning Board (TPB) will hold a hearing tomorrow for public representations on the new Ngau Tam Mei (NTM) Outline Zoning Plan. The traditional farming landscape in NTM has existed for over a hundred years. This rural township has also preserved the industry of ornamental fish aquaculture (particularly koi), an industry that has almost disappeared in Hong Kong. In terms of ecology, NTM is closely linked with the Deep Bay wetlands and the future Sam Po Shue Wetland Conservation Park, and supports Eurasian Otter and many wetland birds. In view of these, the Hong Kong Institute of Landscape Architects (HKILA) and World Wide Fund for Nature Hong Kong (WWF) are proposing four enhancement recommendations, which aims to conserve traditional cultural and historic heritage, build public spaces that can be used by both human and wildlife under the “single site, multiple use” model, and transform NTM into an iconic town of rural ecotourism in the Northern Metropolis.
When proposing these enhancement recommendations, HKILA and WWF aim to:
Create a people-oriented livable city
Achieve a future in which people live in harmony with nature
Promote urban-rural integration
Enhance biodiversity
Adopt Nature-based Solutions (NbS) in the development
Details of the four enhancement recommendations are as follows:
Retain the existing koi fish farming ponds (approximately 7 hectares) east of the NTM UniTown, and transform them into a thematic Koi Park, creating public open space while conserving wetland habitats for various wildlife, preserving Hong Kong’s ornamental fish aquaculture industry, and also promoting innovative themed rural tourism.
Preserve the existing agricultural land and fishponds located within the proposed station plaza and riverside park areas as far as possible, and redevelop them into a Lotus Pond Park (approximately 12 hectares) featuring the characteristic Jiangnan waterscape style. This would provide an open wetland landscape for the city centre, enhance ecological functions, and create a distinctive attraction of local thematic immersive tourism.
Taking the opportunity to revitalise the main NTM river channel and construct a multifunctional blue-green corridor, the artificial channel should be ecologically restored. The existing fishponds and agricultural land within the proposed blue-green corridor (approximately 6 ha) should be preserved to enhance ecological value but also increase landscape diversity. These fishponds and agricultural land could further serve purposes such as flood storage and leisure farming.
At Yau Pok Road, the NTM river channel should be modified to divert part of the river flow into the wetland area between Fairview Park and Palm Springs, which falls under the future Sam Po Shue Wetland Conservation Park. Additionally, the associated “Recreation” zone along Yau Pok Road and the river channel should be rezoned to “Open Space” to serve as an extension of the NTM blue-green corridor to improve ecological connectivity. Furthermore, the permitted building heights for the “Residential (Group A) 2” sites in Areas 4A and 4B should be reduced, adopting a stepped building profile on the side facing the river channel to minimise impacts on birds.
Mr. Paul Chan, President of HKILA, pointed out that: “Through close collaboration between HKILA and WWF, our joint recommendations for Ngau Tam Mei bring together landscape and ecological considerations, aligning with Greater Bay Area strategies such as ecological priority and green development. Transforming existing koi farms and other habitats into thematic parks and blue-green corridors will foster urban-rural integration, promote innovative ecotourism, and build a high-quality, healthy, and biodiverse community that balances growth with diversified landscape.”
Dr. Bosco Chan, Director, Conservation of WWF, shared that “The rural landscapes and traditional cultural heritage of Ngau Tam Mei represent a unique opportunity to integrate nature-based solutions into the Northern Metropolis. Our joint recommendations leverage the existing wildlife habitats and thematic local industries to preserve biodiversity, enhance climate resilience, and develop innovative rural tourism. Ultimately, our aim is to create shared spaces where people and wildlife can thrive together, not just in Ngau Tam Mei but also across the Northern Metropolis.”
HKILA and WWF will attend the public hearing held by the TPB on 6 March to brief the TPB members on our recommendations. HKILA and WWF hope that the TPB and the relevant government departments would consider and adopt our proposal, creating a quality, healthy and green Northern Metropolis. HKILA and WWF also hope that the Government will maintain the dialogue with relevant stakeholders on the development and planning of the Northern Metropolis to achieve a win-win situation.

HONG KONG SAR – Media OutReach Newswire – 5 March 2026 – 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.
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 PolyU, has discovered the mechanoelectrical perception in sea urchin spines. It originates in the spines’ gradient porous structure that generates electrical signals when water flows through it. The team used 3D printing technology to replicate the structure and develop a novel bionic metamaterial sensor.
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.
