Smart hardware players may also remember that there is a smart ring called Oura abroad. On October 27, the third generation Oura 3 smart ring was officially released. Seven kinds of sensors are integrated in a small ring, which supports data detection of heart rate/blood oxygen saturation, exercise, temperature, etc., and can last for 4 days.
Oura 3 smart ring is available in silver/gray/black/gold. It is made of titanium alloy on the outside and transparent plastic on the inside. It is 7.9mm wide, 2.55mm thick, 100 meters waterproof, and weighs between 4 and 6g in different sizes. It uses Bluetooth connection to integrate seven sensors including heart rate, blood oxygen, and temperature.
The Oura 3 smart ring has the same function as the smart bracelet. It supports basic functions such as step counting, movement and sleep monitoring. It has complete functions such as exercise heart rate, route, distance, pace, heart rate recovery prediction, etc. It also supports 24-hour heart rate measurement (the previous generation can only measure heart rate during sleep), and claims that the heart rate measurement accuracy is 99.6%.
It also has 24-hour temperature detection and menstrual period prediction, claiming that it can predict the menstrual period 30 days in advance, and can send a notice 6 days before the start of the menstrual period. However, the detection function of blood oxygen saturation is only enabled during sleep, and it is estimated that OTA will occur in 2022.
The size of this generation is close to that of an ordinary ring, and it has maintained a 4-7 day life (depending on the size of the ring). The charging time is 20-80 minutes (also depending on the size of the ring). The Oura 3 smart ring sells for $299, or about 1900 yuan, on November 15.
Smart rings are suitable for some users who do not want to wear watches/bracelets. I hope the domestic manufacturers will follow up as soon as possible (masochistic. jpg).
