Circular Ring
Introductory price €264
Most often in the form of bracelets, activity sensors are miniaturizing, so much so that we are beginning to find them in the form of simple connected rings. The latest, the ring of the French start-up Circular emphasizes well-being and health, promising monitoring of various parameters that would have nothing to envy to bracelet-type sensors.
This connected Circular ring thus integrates optical sensors to measure heart rate and blood oxygen saturation (SpO2), as well as skin temperature. The data collected is used to analyze the wearer’s activities, monitor his state of health, suggest physical activities or, on the contrary, recovery periods as most activity sensors do.
The Circular also emphasizes sleep monitoring with an analysis of the different phases that make it up and both cardiac and respiratory monitoring, in particular to detect any sleep apnea problems. When it’s time to wake up, the ring can emit vibrations so as not to disturb your bedding companion.
Despite its compactness and lightness (4 g), this ring could work for up to four days, according to its manufacturer, after a full recharge of 60 min. Its waterproofness is guaranteed up to 5 m, according to Circular.
Four interchangeable metal shells are offered to easily offer various finishes: silver, black, yellow gold or rose gold. The Circular ring is already available for pre-order at a price of €264 for an expected arrival on the market between May and July 2022.
