Behind its discreet appearance, a smart ring embeds several sensors capable of tracking various daily data. Here's how this type of connected object concretely works.
Miniaturized sensors in contact with the skin
The ring is equipped with optical and motion sensors, positioned in contact with the finger. They primarily capture heart rate, movements related to physical activity, and certain signals used to estimate sleep.
Synchronization with a mobile application
The ring alone does not have a screen. The recorded data is transmitted via Bluetooth to an application installed on the smartphone, where it is then organized into graphs and trends.
Autonomy designed for continuous use
Thanks to its small size and low power consumption, a connected ring like the COLMI R09 can be worn for several days before needing a recharge, via a portable charging case supplied with the product.
