Xiaomi patent points to a smart ring that can automatically adjust its size

Fitness trackers are mainly available in the form of wearables that resemble a wristwatch, but ‘smart rings’ are becoming increasingly popular, including products from Oura, Ultrahuman and Samsung. Unlike smartwatches with an adjustable strap, smart rings must be purchased in a specific size option that suits the wearer. However, a person’s ring size can change over time for a variety of reasons, which can render the existing smart ring unusable. According to details from a patent document, Xiaomi may be working on a solution to this problem.

Xiaomi Smart Ring patent points to automatic size adjustment function

According to a patent document spotted on the China National Intellectual Property Administration (CNIPA) website of 91mobiles, Xiaomi is developing a ring-shaped wearable device equipped with 5G, Wi-Fi, NFC and ultra-wideband connectivity, as well as a host of sensors. a touch panel, processor and audio components. This is an indication that it is a smart ring that can be used for health tracking.

Unlike other smart rings currently available, the ring described in Xiaomi’s patent has a unique capability that allows it to automatically adjust its size to fit the user’s finger. To enable the wearable to resize, the document discusses the use of two components: an inner ring and an outer ring.

While the outer ring might resemble a regular smart ring, the document notes that the inner ring is made of an elastic material that works with spring mechanisms. Part of the inner ring would protrude from the inner ring, allowing it to “adjust” the size.

It is currently unclear whether such a smart ring from Xiaomi can be produced in one size option that adjusts to any ring size, or whether it will require a few different size options to achieve the automatic size adjustment. The patent also describes using the ring for additional functions, such as controlling connected devices, the release said.

Despite the obvious benefits of the wearable device described in Xiaomi’s patent, it’s worth noting that there’s no guarantee that the company will eventually introduce a smart ring based on the technology described in the document.
