About a week ago, the5krunner published initial information<\/a> on a new wearable from Garmin. Although the device may at first glance appear to be a competitor to the Whoop band, additional information I\u2019ve received points toward a less comprehensive product.<\/p>\n

What is known so far?<\/h2>\n

Garmin is apparently preparing the launch of a product under the name “Index Sleep Monitor.” It\u2019s said to be a comfortable and flexible wearable designed to be worn on the upper arm with a Velcro strap, collecting vital data during sleep \u2013 essentially like one of Garmin\u2019s sports watches with a PPG sensor, but for the upper arm.<\/p>\n

The optical sensor is a separate unit and is housed in a small pocket within the band. The back of the device shows the familiar design of Garmin\u2019s current Elevate sensor. No metallic electrodes are visible, suggesting that ECG-related features are not included.<\/p>\n

There is no display or buttons. Only a small LED next to the PPG sensor indicates battery status. In practice, this LED should not disturb sleep as long as the device is worn correctly. Charging is done via Garmin\u2019s standard charging cable.<\/p>\n

With eight hours of sleep per day, the built-in battery should provide enough power for around seven days.<\/p>\n

The largely passive device can apparently only alert the user via vibration \u2013 for example, as an alarm clock. Tapping the band is intended to suffice for snoozing or stopping the wake-up signal.<\/p>\n

Expected Features of the Index Sleep Monitor<\/h2>\n

Rarely has a Garmin device been more aptly named: The Index Sleep Monitor appears to focus entirely on capturing and analyzing sleep behavior.<\/p>\n

If it is indeed a dedicated sleep-tracking device, its classification within the Index series \u2013 which so far includes the smart scale Index S2<\/a> and the blood pressure monitor Index BPM<\/a> \u2013 would make sense. These devices clearly focus on “passive” health metrics rather than activity or performance data.<\/p>\n

Based on this and what the Elevate sensor is capable of, the Index Sleep Monitor is expected to capture the following metrics:<\/p>\n
