Heart
Single-lead ECG, with heart rate and heart rate variability.
Record a Whole Day With Hexoskin
See How Your Day Shows Up in Your Body
Meetings, commutes, workouts, and quiet evenings each leave a trace in your heart rate and breathing. Hexoskin records them continuously, so you can see which moments raise your heart rate and how quickly it settles.
Put on the shirt in the morning, start the recording, and live your day. Hexoskin keeps ECG, breathing, and movement on one timeline, and Hexoskin OneApp lets you mark the moments you want to revisit. 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.
Context Turns Numbers Into Insight
A climb up the stairs and a tense meeting can produce the same heart rate. Because Hexoskin records movement with every heartbeat and breath, you can tell effort from stillness and see how quickly your body settles afterward. Record the days that matter to you, workdays, travel, training, and rest, and compare them in your Hexoskin dashboard. Over time, your own recordings show what a typical day looks like for you.
Go Further
Once your days are recorded, two questions usually follow: what is normal for you, and how quickly you recover. Each page shows how Hexoskin answers one of them.
Personal Baselines
Your resting heart rate, breathing rate, and heart rate variability are personal. Hexoskin helps you build your own reference from repeated recordings, so you can see when something changes.
Build Your BaselineRest & Recovery Patterns
The minutes after effort say a lot. Hexoskin follows your heart rate and breathing as you go from a workout, a run, or a demanding task back to rest, so you can see how quickly your body settles.
Track Your RecoveryThe Everyday Measures Hexoskin Provides
Every day recorded with the garment gives these measures, from one ECG, two breathing bands, and an accelerometer on the same timeline. Select a measure to read its definition.
Heart Rate
Heart rate is the number of beats per minute from the ECG, averaged over the last 16 heartbeats.
Show the DefinitionHeart rate is the number of beats per minute from the ECG, averaged over the last 16 heartbeats.
Recorded by the textile ECG electrodes.
In the Data

Recorded by the textile ECG electrodes.
In the Data
- Average heart rate

Heart Rate Variability
Heart rate variability is the beat-to-beat variation of the heart, reported as RMSSD, SDNN, and high- and low-frequency power.
Show the DefinitionHeart rate variability is the beat-to-beat variation of the heart, reported as RMSSD, SDNN, and high- and low-frequency power.
Recorded by the textile ECG electrodes.
In the Data
- 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.
- SDNN
- Standard deviation of all NN intervals.
- High-frequency power
- HRV high-frequency (HF) power, from 0.15 to 0.4 Hz, calculated with the Lomb periodogram.
- Low-frequency power
- HRV low-frequency (LF) power, from 0.04 to 0.15 Hz, calculated with the Lomb periodogram.
- HRV quality score
- Ratio of valid NN intervals to all RR intervals over the last 5 minutes, used as a quality score for the HRV results.
RR Intervals
An RR interval is the time between two heartbeats, measured for every beat. It is the basis of every HRV measure.
Show the DefinitionAn RR interval is the time between two heartbeats, measured for every beat. It is the basis of every HRV measure.
Recorded by the textile ECG electrodes.
In the Data
- RR interval
- Time between two heartbeat detections, calculated for every QRS event and saved at the center of the QRS complex.
- NN interval
