It’s an understatement to say we are glued to our cellphones. Every ping, beep, or buzz has us reaching to pick them up. But the question is: will we be doing the same in 10 or 15 years? What if we are not using phones at all? It’s hard to imagine, but maybe we’ll be communicating through some other technology.
The same goes for wearable technology like smartwatches, which began with capabilities like displaying digital time, translating text, and playing games. These devices are not only becoming more convenient to use, but they are also providing more advanced information that will change lives, and maybe even save them, too.
Modern wellness wearables really took off in the late 1990s and early 2000s, as mass-produced microchips allowed companies to offer the consumer market a wearable minicomputer, like the once-ubiquitous Fitbit. At the same time, manufacturers were producing water-resistant, durable silicone bands that protected the sensitive electronics inside.
At that point, wearable devices were pretty basic in what they tracked: steps counted, distance travelled, and pace. Today’s medical wearables have made giant leaps. Instead of passively tracking activity, they can monitor the wearer’s biosystems and provide data on how your body is functioning. Now that AI is advancing rapidly, these wearables can take that data and generate personalized health baselines and project trends. Data on heart rate variability, sleep quality, and blood oxygen levels can all be brought together to monitor for potential illnesses.
Today’s medical wearables can do all of this because their sensors have become far more sophisticated. Some now include medical-grade ECGs, SpO2 monitors (which track blood oxygen levels) and even early-stage non-invasive glucose monitoring (for blood sugar levels) that rivals the accuracy of traditional medical equipment.
Not only are the sensors more elaborate, but the form these devices take is also expanding. In the past, most were worn on the wrist like a watch, but now they are discreet, appearing as skin patches, hearing aids, and rings.
Rings in particular are maturing into what are called “productivity companions,” capable of gesture control and syncing with other smart devices nearby. Similarly, smart hearables and hearing aids have become “always on” health monitors that gather information while sitting in the ear canal.
Smart patches can now be completely concealed and used to track glucose levels for people living with diabetes who depend on medication to keep their levels in the normal range. As of early 2026, smart patches have moved beyond the standard 10-day replacement cycle, offering 14 to 15 days of wear time, or in some cases up to six months for implantable systems, according to Erin Poche’s article for T1D Strong, a guide for people living with type 1 diabetes.
Innovation has ushered in a new era of self-monitoring, freeing people to take control of their health on their own terms.
In Deb Balzer’s article for the Mayo Clinic, Dr. Jeannie Bailey, associate professor of orthopedic surgery and director of the Physical Function and Biomechanics Research Core at the University of California, San Francisco, notes how important self-monitoring can be: “This tracking really enables patients to take ownership and think about their own progress, and it gives them that feedback,” says Dr. Bailey. “They see how they’re doing better, they’re getting hopeful and it’s definitely affecting them.”
Also of note, the Harvard Business Review examined how medical centers are making wearables part of their treatment approach. AZ Maria Middelares in Belgium is offering home monitoring after heart surgery, where clinicians intervened early in 33 percent of patient cases. “One of the most significant advantages is the ability to screen for atrial fibrillation at an early stage while the patient is already at home. In such cases, patients can be instructed to record a short electrocardiogram,” says Dr. Koen Cathenis, head of cardiac surgery at AZ Maria Middelares. “Based on this data, in my experience, we have promptly adjusted medication, either directly or via the general practitioner, which allowed us to intervene quickly and effectively.”
For manufacturers, the process of making wearable medical devices is moving toward what is called autonomous agility: AI-driven systems and robots that operate independently, adapt to unpredictable environments, and make real-time decisions. The shift, in short, is from rigid automation to far greater versatility in what can be produced.
Another major innovation for manufacturers is additive manufacturing. This process is particularly well-suited to wearables because it can print directly onto thin, stretchable polyamide or elastomeric fabrics. Micro 3D printing, meanwhile, has enabled the miniaturization of internal components, allowing more technology to be packed into smaller, more discreet devices while supporting increasingly complex diagnostics.
As for the industry itself, business is booming. The medical wearables market is projected to grow from $55 billion in 2026 to $114 billion by the end of 2031, according to a recent report from Mordor Intelligence.
A number of factors are driving this growth. Chief among them is the rise of AI, which adds a whole new level of functionality: from establishing a personal health baseline to predictive analysis that flags potential issues so users can take preventive action.
The timing is also right. The global population is aging and will require more complex care. For younger users, the focus is on performance optimization; for older users, these devices can provide a meaningful degree of autonomy, delivering medical-grade information that allows people to age in place while still receiving the supervision they need.
One of the most promising aspects of these wearables is their predictive capability. This could lead to forecasting potential illnesses based on physiological changes, letting you know you may be coming down with a cold before it gets the better of you. There is also significant mental health potential. The journal Nature reported on wearable devices for anxiety assessment, with authors noting: “Anxiety disorders are common but detecting them in everyday life can be difficult. Wearable devices can record body signals that change with anxiety, including heart activity, breathing, skin responses and blood flow.” Combining several signals yields more accurate results than relying on a single one, with heart activity identified as the most reliable individual signal.
Closely linked to AI integration is the role wearables play as a personalized data pipeline. This will go well beyond hitting 10,000 steps a day; these devices can offer advice on personal nutrition, cortisol levels, and even genetics, empowering users to make meaningful lifestyle adjustments.
The long view is this: as they continue to grow more powerful, medical wearables will transform how we live, and hopefully make us healthier in the process.
