Another big tech company is working on a smart ring

Samsung’s upcoming and heavily leaked Galaxy Ring may be getting all the attention right now, especially with Samsung Galaxy Unpacked around the corner in July. However, it looks like Samsung may have an additional competitor soon. According to a report by Gadgets & Wearables, a patent was filed with the U.S. Patent and Trademark Office (USPTO), and it reveals that a new Fitbit smart ring is in the pipeline.

The patent, titled “Ring for optically measuring biometric data,” describes it as a “ring-shaped wearable device for detecting biometrics with a light source and photodetector.” The patent was first submitted in June 2021, but it’s only been granted now.

The 20-page patent document also reveals a slew of specs and features we can expect. According to the filing, the new Fitbit ring will use a lot of Fitbit’s existing technology. It’s expected to have multiple sensors to monitor heart rate, oxygen levels, and possibly stress levels through skin conductivity measurements. The big focus would be on fitness and sleep tracking, and there’s a specific mention in the filing of SpO2 monitoring to keep track of blood oxygen saturation. These are all features that Fitbit smartwatches already offer, but the challenge for Fitbit will be making them small enough to fit on a smart ring.

While this is a challenge, it shouldn’t be a big one for Fitbit. These sensors already exist on the Oura Ring, RingConn Smart Ring, Ultrahuman Ring Air, Zepp Health, Helio Ring, and others. The patent comes with various illustrations that show a smart ring that doesn’t look very different from others already on the market. There are some different clasping mechanics, including an “elastic element” and other unspecified mechanisms.

We would expect the Fitbit ring to pair with the Fitbit app via Bluetooth or NFC. In the coming year, Fitbit is also expected to incorporate an AI coach into its services.

All this said, a patent filing isn’t necessarily a guarantee that a device is coming. Many companies file patents simply to hold on to an idea that never sees the light of day. However, with many smart rings already on the market and the Galaxy Ring upcoming, we’d be shocked if Fitbit never released a smart ring, even if it may not necessarily resemble what’s shown in the filing. Fitbit is well positioned to enter the smart ring market, and it could do particularly well if it released a more affordable alternative to the Oura Ring and Samsung’s Galaxy Ring.

Ultrahuman, the maker of the Ultrahuman Ring Air, is making its way to U.S. production grounds. The company is setting up a production facility in Indiana, which will mark the first time a smart ring from Ultrahuman will be assembled from scratch on U.S. soil.

“The UltraFactory will offer an end-to-end production capability and is based on the company’s first operational model of such a facility in India,” the company says.

Is the Oura Ring waterproof?

The Oura Ring is a highly sought-after wearable device available in different styles and price ranges. It allows users to track their sleep and recovery, stress levels, illnesses, and fitness routines -- and it even provides features specific to women's health. With so many features,  you might wonder whether the watch is waterproof. Let's find out.
Is the Oura Ring waterproof?
Technically, the Oura Ring is not waterproof. Instead, it's water-resistant up to 330 feet (100 meters). This is the case for most modern gadgets. You'll often find water resistance protection on products, which is good, but it's not exactly the same as being waterproof. But what does that really mean? We explain below.
Can you go swimming with the Oura Ring?
The Oura Ring has a certain level of protection that allows you to wear it while swimming, showering, and snorkeling. However, wearing the Oura Ring during scuba diving or when there is a risk of extended water submersion or extreme pressure is not advisable. Oura recommends avoiding wearing the ring in such scenarios to ensure its longevity and proper functioning.

Oura further explains: "The Oura Ring operating temperature ranges from [-10 to 52 degrees Celsius and 14 to 125 degrees Fahrenheit]. You can safely wear your ring in the shower, hot tubs, saunas, ice baths, and cryotherapy tanks. However, extended exposure to extreme temperatures (below 0°C/32°F or above 35°C/95°F) may lead to battery damage."
How does this compare to other smart rings?
Of Oura's chief competitors, only the Ultrahuman Ring Air provides similar water resistance. By contrast, the Amovan Smart Ring only provides water resistance up to 50 meters. The Oura Ring offers the same level of protection as the Apple Watch Ultra, making it an excellent alternative to smartwatches. However, it surpasses the Apple Watch Series 2 or later and the Google Pixel Watch 2, which can only resist water up to 50 meters.
