A Smarter Running Partner

A 24/7 Health Companion

▲Securing computational design data through 4D scanner

Developing wearables with the optimal fit and comfort remains a difficult yet crucial challenge. Not only do these factors make the device feel more seamless to use, but they are directly tied to maximizing overall performance and sensor accuracy. However, the fact that each person’s anatomy is completely unique presents a major hurdle. But what if there was a way to meticulously engineer comfort, fit and sensing so precisely, it could deliver the optimal experience for nearly everyone?

Samsung’s solution is Computational Design. This multidimensional process harnesses AI and advanced computing to analyze hundreds of thousands of quantitative and qualitative data points to generate, test, and refine product designs with greater precision. The result is a fundamental shift from subjective feedback to objective, data-driven engineering, creating superior products with the optimal fit for the widest range of users.

That description captures computational design in the abstract—like a dictionary definition. To understand how computational design is actually used to create superior wearables, Samsung Newsroom visited the Samsung Design Innovation Center (SDIC) in San Francisco, home to the Computational Design Lab.

Federico Casalegno, EVP and Head of the Samsung Design Innovation Center

Spearheading the SDIC is Federico Casalegno, Executive Vice President and Head of the Samsung Design Innovation Center, who has spent the past two decades mastering the practice of computational design and leading the implementation of this core concept into Samsung’s product development. We sat down with Federico to discuss how SDIC employs computational design as a primary tool to create and optimize experiences for Samsung’s wearables, particularly the Galaxy Buds4 series.

Q. Tell us about SDIC’s role.

At SDIC, our mission is to deliver meaningful experiences by understanding people and their evolving lifestyles—always in the context of human-centered design. Ultimately, we want to delight customers and create products that help people live happier, healthier, more creative, and more productive lives, while building a better future for all and preserving the environment. To achieve this, SDIC brings together the power of design and creativity with data-driven decision-making. Supported by AI, machine learning, robotics, and advanced computing, our talented, multidisciplinary team of designers is constantly pushing the boundaries of what’s possible, delivering unparalleled user experiences and real, tangible benefits.

At SDIC, design is combined with AI, data, and computing to achieve maximum comfort for wearable devices.

Q. What exactly is computational design, and what is the philosophy behind it?

While we live in a unique era of technological innovation, Samsung’s approach to design was always deeply human-centered as we believe that technology without humanity is merely perfection without purpose. Computational design is how we bring this philosophy to life—it is the process of harnessing the immense power of AI, data, and computing to design products for people, rather than expecting people to adapt to our products. This approach helps us to create devices that are fundamentally functional, intuitive, comfortable and beautifully crafted. Today, this methodology is applied all across our wearable portfolio, including Galaxy Watch8 and Galaxy Buds4 series.

The computational design process involves various state-of-the-art testing equipment, including 4D scanning.

Q. How does computational design turn the ‘fit’ of a device into an objective, measurable metric?

For developing something as personal as a wearable that remains in contact with you for extended periods, fit is an essential element. It’s not just about comfort though; a secure fit is also needed for maximizing the precision of the device’s sensors. However, traditional design methods fail to measure wearability objectively, as they only rely on a small sample of people for product testing.

Computational design fundamentally changes this. By leveraging massive, digitalized datasets and advanced AI simulations, it transforms wearability into a quantifiable metric that allows Samsung to measure comfort and fit like never before. By being able to consider all the unique shapes and curves of the human ear or the wrist through computational design, our designers are equipped with trustworthy, objective insights that are difficult to attain through traditional methods.

Optimal design parameters are derived through AI and physics-based simulations, which are then cross-verified with robot testing

Q. Tell us in detail how the computational design process works in the lab, and how it was implemented in the Buds4 series.

Our computational design process relies on three elements: real people, digital twins, and robots. We capture 3D and 4D scans of a diverse global audience, integrating precise anatomical data to create ‘digital twins.’ We then run AI and physics-based simulations, cross-validating the results with physical robot testing.

For the Buds4 series, we applied this exact process to achieve perfect wearing comfort and premium sound. We analyzed hundreds of millions of global ear data points and ran more than 10,000 simulations to perfect the new blade design. This objective data led us to subtly reduce the size of the main head[1] and refine the angle of rotation—minor adjustments that resulted in a dramatic, universally validated increase in stability and comfort.

Q. How does Samsung’s computational design ultimately benefit the users?

Samsung’s computational design process is powered by a unique proprietary dataset built exclusively from within Samsung, and our team has developed several specialized AI programs based on this data. This combination gives us unique insights while we constantly innovate our design processes and methods. For Galaxy Buds and Watch specifically, this translates into improved wearing comfort, stability and sensor accuracy—key factors that elevate both the user experience and product performance.

Samsung’s lineup of wearables, such as Galaxy Buds4, Galaxy Watch8, and Galaxy Ring, all incorporate computational design in its development process.

Q. Looking ahead, how do you see Computational Design evolving over the next decade?

Computational design is now a foundational element of Samsung’s development process across all our wearable products. Our goal remains to maximize wearability, fit, comfort and sensor performance to ultimately serve the people using it.

Looking ahead, the true power of this process is its continuous evolution. As our dataset continues to grow, custom AI tools will drive more accurate simulations and deeper insights. These advancements will not only further improve product wearability, but also unlock exponential innovations down the line that lead to an entirely new category of wearables that can redefine the boundaries of user experience. Ultimately, this symbiotic partnership between computational design and AI frees our designers to be more creative, empowering us to deliver measurably superior products and experiences for the people who use them.

Samsung’sAntioxidant IndexonGalaxy Watch8transforms what once seemed like science fiction into everyday technology. In five seconds, a thumb scan returns precise carotenoid levels – the industry’s first measurable nutrition index.

By miniaturizing lab-grade sensor technology with exceptional accuracy, it turns your diet into an actionable metric for healthier aging. Establishing this new benchmark in wearable health tracking required years of intensive R&D, countless prototypes and unwavering grit.

Breaking New Ground in Nutrition Tracking

Back in 2018, Samsung saw a critical gap in wearables: we could count every step and calorie, yet there was no simple way to measure how our diet impacted our health. Deeper nutritional insights were locked behind expensive and time-consuming lab tests, out of reach for many people.

As people live longer, the focus is shifting from simply increasing lifespan to improving the quality of those additional years.

“In this context, antioxidation naturally gains attention as a method to slow down aging,” explains Dr. Hyojee Joung, a Seoul National University¹public health nutrition expert who guided parts of the tech’s development. “If antioxidant management is neglected, Reactive Oxygen Species (ROS) accumulate in the body, increasing the risk of chronic diseases such as cardiovascular disease, diabetes and cancer.”

This realization made antioxidants the cornerstone of Samsung’s mission. Engineers and scientists focused on carotenoids – key antioxidants and proven indicators of fruit and vegetable intake – to create a device small enough to sit on your wrist, yet powerful enough to turn complex antioxidant data into simple, actionable health insights for everyone.

The first prototype of the spectroscopy-based antioxidant sensor.

A clinical-ready version of the sensor.

A prototype designed for use in skincare products.

Challenge #1: How to Shrink the Lab-Grade Sensor Technology

From day one, the dream of a nutrition-tracking wearable hit an immediate snag: traditional methods for measuring carotenoid levels like Raman spectroscopy are laser-based, non-invasive and precise, but rely on bulky machines that are far from wearable. So the team’s first mission was to shrink the lab-grade tech into a coin-sized sensor.

After seven years of rigorous testing and optimizing since the first prototype, the team developed theminiaturized sensor, a groundbreaking tech that combines multi-wavelength LEDs with a custom photodetector array to provide accurate carotenoid readings in a compact design.

“Our breakthrough was integrating reflectance spectroscopy with LEDs, which allowed us to miniaturize the technology while maintaining a high level of accuracy,” explains Jinyoung Park, a developer from Digital Health team at Samsung Electronics.

▲ Galaxy Watch8’s LED-PD sensor modules.

Unlike lasers, which emit a sharp, narrow wavelength, LEDs emit a broader wavelength range. By analyzing how much light is absorbed by the skin at multiple wavelengths through photodiodes², the watch estimates carotenoid levels with impressive accuracy. The advanced algorithms that continuously calibrate in real-time also support precision while delivering personalized insights to each user.

▲ The LED-PD prototype testbed at the back of Galaxy Watch8.

Challenge #2: How to Ensure the Tech Reaches Everyone

Creating a coin-sized carotenoid sensor was a major milestone, but the next challenge was ensuring it could work accurately and reliably across diverse skin types, making it truly accessible to everyone.

To overcome challenges like melanin interference in darker skin tones, Samsung’s engineers opted to use the fingertip for measurements since it has the least melanin across all ethnic groups. They also added simple tweaks, like light fingertip pressure during scans, which helps temporarily reduce blood flow and hemoglobin interference, making the results more accurate.

Extensive trials conducted at Samsung Medical Center³ included hundreds of participants, validating the sensor’s performance. This paved the way for a feature that seamlessly transitioned from the lab to users worldwide, offering an inclusive solution designed for everyday life.

How It Works

Carotenoids are the natural red, yellow and green pigments found in fruits and vegetables. Since our bodies can’t produce carotenoids on their own, the levels stored in the body offer a clear snapshot of how much fruit and vegetables someone has been eating.

This is where your Antioxidant Index score comes in, reflecting your carotenoid levels based on these categories:

• Very low: Less than 50% of the daily WHO recommendation of 400g per day.
• Low: Between 50%–100%.
• Optimal: 100% or more.

“Skin carotenoids metabolize and accumulate in tissues gradually, so short-term changes in fruit and vegetable intake won’t immediately appear in the score,” explains Dr. Hyojee Joung. “Our research shows that increased carotenoid intake leads to a meaningful rise in skin carotenoid levels after about one to two weeks, making the Index a valuable tool for tracking consistent, long-term dietary habits.”

Lifestyle factors like sleep quality, stress levels, and physical activity also influence the Index, making it a well-rounded indicator of overall health. Paired with otherGalaxy Watch8 featureslikesleep coaching,activity trackingandVascular Loadmonitoring, the Antioxidant Index offers a holistic view of your well-being, empowering smarter decisions for healthier aging.

▲ The Antioxidant Index feature measures carotenoid levels in seconds with the sensor on the back of the Galaxy Watch8 and provides additional nutritional insights on paired Galaxy smartphones.

Your Health, Reimagined

“New wearable sensors can play a role in helping people build healthy eating habits by tracking and encouraging sufficient daily intake of fruits and vegetables,” says Professor Yoonho Choi from Samsung Medical Center. “Over time, this simple practice can help prevent some cancers and other age-related diseases, making it a very effective way to support long-term health.”

Antioxidants are an emerging area of focus, but research has been limited due to the challenges of accurate measurement. Galaxy Watch8’s Antioxidant Index goes beyond current industry developments and delivers meaningful innovation.

Samsung’s ability to measure antioxidant levels with precision, acknowledged by experts as a benchmark for future research, represents a breakthrough in health monitoring. By helping users identify risks early and take proactive steps towards better health, Samsung is paving the way for a smarter, more proactive approach to wellness and redefining the role of wearables in preventative healthcare.

Today, more than ever, people are defining their own wellness goals. From looking to stay fit or gaining more muscle mass, achieving better sleep, or caring for personal or family physical and mental health issues, everyone’s goals for better health look different. But one thing is common, the daily management and path towards these goals can be complicated and challenging, and most importantly, it is defined by you.

That’s why at Samsung, we’re working to empower more people to manage their health —and those they care for —their way, with a comprehensive, yet simplified approach to everyday wellness.Our vision is to improve the health of billions through connected care centered around the home by connecting devices, services and people —like only Samsung can.

This approach comes to life in our wearables portfolio with upcoming features like My Vitality Score¹and Booster Card,²combining more data with new intelligent analysis to deliver even more personalized and actionable guidance day and night.

Bringing It All to Life Starting With a Good Night’s Sleep

With more data and greater intelligence, users will receive even more insights for preventative wellness end-to-end solutions, starting with sleep. We’ve developed a variety of features that offer users a deeper understanding of their sleep quality and other aspects of their health during sleep. For example, the sleep apnea feature, which recently receivedDe Novo clearance from US FDA, will detect signs of moderate to severe obstructive sleep apnea —and often undiagnosed and untreated —chronic medical condition, so they can address it with their healthcare provider.

This is just the beginning. We’reworking with partnersto connect these capabilities to real world solutions and services that expand access to healthcare in the home. For instance, you can create a more optimal sleep environment with a smart mattress that can fine-tune the ideal sleep temperatures for rest.

Samsung Electronics today announced that the Irregular Heart Rhythm Notification (IHRN) feature¹of the Samsung Health Monitor app²has received FDA clearance. Together with the app’s existing on-demand Electrocardiogram (ECG) function,³the IHRN feature proactively monitors heart rhythms suggestive of atrial fibrillation (AFib), right from their wrist.

“We’re excited to announce that Irregular Heart Rhythm Notification, designed to help millions of people around the world who may not be aware of a potential heart risk, has been cleared by the FDA,” said Hon Pak, Vice President and Head of the Digital Health Team, MX Business at Samsung Electronics. “This is yet another example of how Samsung prioritizes proactive safety solutions and enables users to receive a more holistic understanding of their cardiovascular and overall health.”

Cardiovascular disease remains one of the world’s leading causes of death and AFib—a type of arrhythmia—is widely considered a warning sign for major cardiovascular issues that can increase the risk of stroke, heart failure and other cardiovascular complications. Moreover, some of AFib cases are asymptomatic or even silent, leaving people unaware of their risk.

That’s why Galaxy Watch offers tools to help users better understand their heart health using the Samsung BioActive Sensor, including on-demand ECG recording and HR Alert function⁴that detects abnormally high or low heart rates. The addition of the new IHRN feature enables Galaxy Watch users to monitor another aspect of their health.

Once activated in the Samsung Health Monitor app, the feature will check for irregular heart rhythms in the background via Galaxy Watch’s BioActive Sensor. If a certain number of consecutive measurements are irregular, Galaxy Watch warns the user of potential AFib activity, prompting them to take an ECG using their watch for a more accurate measurement.

The Irregular Heart Rhythm Notification feature will be available as part of the newly announcedOne UI 5 Watch, coming first to the upcoming Galaxy Watch devices later this year and later expanding to previous editions.

¹ The IHRN feature is not intended to provide a notification on every episode of irregular rhythm suggestive of AFib and the absence of a notification is not intended to indicate no disease process is present. It is not intended for users with other known arrhythmias or users under 22 years old.
² Due to market restrictions in obtaining approval/registration as a Software as a Medical Device (SaMD), it only works on watches and smartphones purchased in the markets where service is currently available (however, service may be restricted when users travel to non-service countries).
³ The ECG app is only available in select markets. The ECG app is not intended to replace traditional methods of diagnosis or treatment. The ECG app is not intended for users with known arrhythmias other than AFib or users under 22 years old. Users should not interpret or take clinical action based on the device output without consultation of a qualified healthcare professional.
⁴ The HR Alert function is for general health and wellness purposes and is not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment or prevention of disease.
⁵ Availability may vary by market, carrier, model or a paired smartphone. Available on Galaxy Watch4 series and later models.
