Iris smart ring with professional blood pressure sensor has been unveiled
The Iris smart ring is crowdfunding on Kickstarter. The wearable features a PPG sensor with six photodetectors and 18 LEDs. For context, the company suggests that competitor models have, on average, two photodetectors and four LEDs. You can use the Iris ring to measure biometrics such as heart rate, HRV and blood oxygen level, plus you can also track your workouts, sleep quality and stress levels. All of this data can be viewed in an accompanying app. The gadget features a medical-grade thermometer and blood pressure sensor; blood pressure measurements will be available from mid-2024, thanks to an OTA upgrade.
The company claims that Iris is the slimmest smart ring, 5 mm wide and 2.5 mm thick, containing the smallest patented sensor. The ring weighs under 5 g (~0.18 oz) and has a wireless docking station that can provide up to four total charges. Another listed difference of Iris versus existing models on the market is improved accuracy; according to the campaign page, the size of other rings can mean they move on the finger reducing the precision of measurement,
The product has a lower price point than models such as the Oura ring, which starts at US$299. The lowest Kickstarter campaign pledge level for the Iris smart ring is CHF137 (~US$146), which will buy you the black version of the wearable and give you a lifetime app subscription. The gold and silver models are slightly more expensive at CHF 155 (~US$165) for the same package. The ring will eventually retail for US$199; the subscription will cost US$10 per month.
