Single-lead ECG, with heart rate and heart rate variability.
Track Your Nights With Hexoskin
See What Happens While You Sleep
Hexoskin records your heart, breathing, and movement through the night, so you can see how your nights unfold and how changes in your routine show up in them.
Wear the shirt to bed and start the recording. Hexoskin keeps ECG, breathing, and movement on one timeline through the night, and your dashboard shows the summary of each night with the signals behind it. Washable, in men’s, women’s, and junior sizes.
Breathing
Two textile bands for breathing rate, tidal volume, and minute ventilation.
Movement & Sleep
Activity, steps, cadence, sleep position, and sleep phases.
App & Dashboard
Live values in Hexoskin OneApp, full sessions in your dashboard, exports in CSV or EDF.
A Night Is More Than Its Summary
A sleep score tells you how the night went. The heart rate, breathing, and movement behind it show when you settled, when you woke, and how quickly your heart rate came down. Hexoskin sleep staging is validated against polysomnography, and recording night after night shows what a typical night looks like for you.
The Sleep Measures Hexoskin Provides
Every night recorded with the garment gives these measures, from the same ECG, breathing, and movement signals. Select a measure to read its definition.
Total Sleep Time
Total sleep time is the time spent in any sleep phase during the night.
Show the DefinitionTotal sleep time is the time spent in any sleep phase during the night.
In the Data
- Total sleep time
- Time spent in any sleep phase.
- Sleep phase changes
- Onset of each change in sleep phase.
Sleep Efficiency
Sleep efficiency is the proportion of time in bed spent asleep.
Show the DefinitionSleep efficiency is the proportion of time in bed spent asleep.
In the Data
- Sleep efficiency
- Proportion of time asleep over the time in bed.
- Sleep percent
- Proportion of time asleep over the sleep time, defined as the time in bed minus the sleep latency.
Time to Fall Asleep
Time to fall asleep, or sleep latency, runs from the start of the sleep recording to the first detected sleep phase.
Show the DefinitionTime to fall asleep, or sleep latency, runs from the start of the sleep recording to the first detected sleep phase.
In the Data
- Time to fall asleep
- Time from the start of the sleep activity to the first detected sleep phase, also called sleep latency.
Sleep Phases
Sleep phases show when the night moves between wake, REM, and non-REM sleep, with the distribution of each phase.
Show the DefinitionSleep phases show when the night moves between wake, REM, and non-REM sleep, with the distribution of each phase.
In the Data
- Sleep phase changes
- Onset of each change in sleep phase.
- Sleep phase distribution
- Distribution of sleep phases over the night.
REM and Non-REM Time
REM and non-REM time are the totals spent in each type of sleep, from sleep onset to the last awakening.
Show the DefinitionREM and non-REM time are the totals spent in each type of sleep, from sleep onset to the last awakening.
In the Data
- REM time
- Total time in REM sleep during the sleep period, from sleep onset to the last awakening.
- Non-REM time
- Total time in non-REM sleep during the sleep period, from sleep onset to the last awakening.
Wake Time
Wake time is the total time awake between sleep onset and the last awakening.
Show the DefinitionWake time is the total time awake between sleep onset and the last awakening.
In the Data
- Wake time
- Total time awake during the sleep period, from sleep onset to the last awakening.
Sleep Position
Sleep position is the time spent on the back, the belly, each side, or upright.
Show the DefinitionSleep position is the time spent on the back, the belly, each side, or upright.
Recorded by the three-axis accelerometer in the recorder.
In the Data
- Sleep position changes
- Onset of each change in sleeping position.
- Sleep position distribution
- Distribution of sleeping positions over the night.
Position Changes
Position changes count how often the sleeping position changes during the night.
Show the DefinitionPosition changes count how often the sleeping position changes during the night.
Recorded by the three-axis accelerometer in the recorder.
In the Data
- Position changes
- Number of sleeping-position changes detected during the night.
- Onset of each change
- Onset of each change in sleeping position.
Heart Rate at Night
Night heart rate gives the average, minimum, and maximum heart rate across the night, from the ECG.
Show the DefinitionNight heart rate gives the average, minimum, and maximum heart rate across the night, from the ECG.
Recorded by the textile ECG electrodes.
In the Data
- Average heart rate
- Average heart rate for the selected range (activity) or recording.
- Minimum heart rate
- Minimum heart rate for the selected range (activity) or recording.
- Maximum heart rate
- Maximum heart rate for the selected range (activity) or recording. In a user profile, it gives the user’s overall maximum heart rate.
Heart Rate Variability at Night
Night heart rate variability gives the high- and low-frequency HRV power recorded during sleep.
Show the DefinitionNight heart rate variability gives the high- and low-frequency HRV power recorded during sleep.
Recorded by the textile ECG electrodes.
In the Data
- Average high-frequency power
- Average HRV high-frequency power.
- Average low-frequency power
- Average HRV low-frequency power.
- RMSSD
- Root mean square of the successive differences between normal RR (NN) intervals, a time-domain measure of heart rate variability. It is calculated on NN intervals rather than all RR intervals to exclude as many noise artifacts as possible.
Breathing Rate at Night
Night breathing rate gives the breaths per minute and their range across the night, from both breathing bands.
Show the DefinitionNight breathing rate gives the breaths per minute and their range across the night, from both breathing bands.
Recorded by the thoracic and abdominal breathing bands.
In the Data
- Average breathing rate
- Average breathing rate for the selected range (activity) or recording.
- Minimum breathing rate
- Minimum breathing rate for the selected range (activity) or recording.
- Maximum breathing rate
- Maximum breathing rate for the selected range (activity) or recording.
Activity at Night
Night activity is the movement intensity through the night, from the three-axis accelerometer.
Show the DefinitionNight activity is the movement intensity through the night, from the three-axis accelerometer.
Recorded by the three-axis accelerometer in the recorder.
In the Data
- Average activity
- Average activity level for the selected range (activity) or recording.
- Actigraphy
- Actigraphy signal based on the accelerometer intensity vector, averaged over the last second.
Sleep phases come from the ECG, both breathing bands, and the accelerometer together. The Hexoskin sleep algorithm was compared with polysomnography in young healthy adults.
