Forget smartwatches, your clothes could soon track your health


Wearable tech might be heading for a reset. We’ve already seen less intrusive devices like smart rings take off, but researchers are now pushing things further by stitching health tracking directly into clothing.

Researchers at National University of Singapore have developed a new battery-free textile system that can monitor blood pressure in real time, potentially turning everyday clothing into a full-time health tracker. The system, detailed in a recent Nature Electronics paper and reported by Tech Xplore, removes one of the biggest limitations of wearable, which is the need to constantly recharging the gadgets.

How the smart fabric breaks the wearable mold

Rather than relying on a built-in battery, the smart fabric uses ultra-thin sensors that stick directly to the skin and connect through a specially designed fabric. A “metamaterial” is at the center of this system, which is a carefully engineered fabric that wirelessly transfers power from a nearby smartphones to the sensors.

The setup splits power delivery and data communication into separate frequency channels that can help avoid interference and keeps the signal stable. In simpler terms, your phone acts as both the power source and the data hub that actively collects health data. So you won’t have to deal with the hassle of charging multiple gadgets.

Real-time tracking, even during workouts

The system focuses on monitoring systolic blood pressure, which measures the force of blood flow during heartbeats. In early tests, it was able to track these readings accurately even while users were exercising. This is where many wearable sensors struggle. So the level of consistency can be useful for long-term health tracking or early detection of cardiovascular issues.

The sensors themselves are extremely thin and flexible, designed to sit directly on the skin without getting in the way of movement. The textile layer then connects multiple sensors into a network, allowing continuous data collection across the body.

Battery-free wearables have been explored before. Though this approach does bring everything together into something closer to real-world use. By embedding the system into fabric, the researchers are pushing toward clothing that works as a passive health monitor rather than a separate device you have to remember to wear.

After being teased in the second beta, the new “Bubbles” feature is finally available in Android 17 Beta 3. This is the biggest change to Android multitasking since split-screen mode. I had to see how it worked—come along with me.

Now, it should be mentioned that this feature will probably look a bit familiar to Samsung Galaxy owners. One UI also allows for putting apps in floating windows, and they minimize into a floating widget. However, as you’ll see, Google’s approach is more restrained.

App Bubbles in Android 17

There’s a lot to like already

First and foremost, putting an app in a “Bubble” allows it to be used on top of whatever’s happening on the screen. The functionality is essentially identical to Android’s older feature of the exact same name, but now it can be used for apps in addition to messaging conversations.

To bubble an app, simply long-press the app icon anywhere you see it. That includes the home screen, app drawer, and the taskbar on foldables and tablets. Select “Bubble” or the small icon depicting a rectangle with an arrow pointing at a dot in the menu.

The app will immediately open in a floating window on top of your current activity. This is the full version of the app, and it works exactly how it would if you opened it normally. You can’t resize the app bubble, but on large-screen devices, you can choose which side it’s on. To minimize the bubble, simply tap outside of it or do the Home gesture—you won’t actually go to the Home Screen.

Multiple apps can be bubbled together—just repeat the process above—but only one can be shown at a time. This is a key difference compared to One UI’s pop-up windows, which can be resized and tiled anywhere on the screen. Here is also where things vary depending on the type of device you’re using.

If you’re using a phone, the current bubbled apps appear in a row of shortcuts above the window. Tap an app icon, and it will instantly come into view within the bubble. On foldables and tablets, the row of icons is much smaller and below the window.

Another difference is how the app bubbles are minimized. On phones, they live in a floating app icon (or stack of icons) on the edge of the screen. You are free to move this around the screen by dragging it. Tapping the minimized bubble will open the last active app in the bubble. On foldables and tablets, the bubble is minimized to the taskbar (if you have it enabled).

Now, there are a few things to know about managing bubbles. First, tapping the “+” button in the shortcuts row shows previously dismissed bubbles—it’s not for adding a new app bubble. To dismiss an app bubble, you can drag the icon from the shortcuts row and drop it on the “X” that appears at the bottom of the screen.

To remove the entire bubble completely, simply drag it to the “X” at the bottom of the screen. On phones, there’s also an extra “Manage” button below the window with a “Dismiss bubble” option.

Better than split-screen?

Bubbles make sense on smaller screens

That’s pretty much all there is to it. As mentioned, there’s definitely not as much freedom with Bubbles as there is with pop-up windows in One UI. The latter allows you to treat apps like windows on a computer screen. Bubbles are a much more confined experience, but the benefit is that you don’t have to do any organizing.

Samsung One UI pop-up windows

Of course, Android has supported using multiple apps at once with split-screen mode for a while. So, what’s the benefit of Bubbles? On phones, especially, split-screen mode makes apps so small that they’re not very useful.

If you’re making a grocery list while checking the store website, you’re stuck in a very small browser window. Bubbles enables you to essentially use two apps in full size at the same time—it’s even quicker than swiping the gesture bar to switch between apps.

If you’d like to give App Bubbles a try, enroll your qualified Pixel phone in the Android Beta Program. The final release of Android 17 is only a few months away (Q2 2026), but this is an exciting feature to check out right now.

Android’s new desktop mode is cool, but it still needs these 5 things

For as long as Android phones have existed, people have dreamed of using them as the brains inside a desktop computing setup. Samsung accomplished this nearly a decade ago, but the rest of the Android world has been left out. Android 17 is finally changing that with a new desktop mode, and I tried it out.
