A good fit for research like this
Choose it when your data has to come from beyond the fixed laboratory — with movement and daily life included
Service validation
Projects connecting wearable data to an app or a digital healthcare service
Working from derived metrics
Teams that need HR and HRV metrics alongside the raw data
From measured signal to research-ready data
PPG and IMU are captured together and motion noise is corrected. Researchers who need the raw signal can take the raw data; teams that need to move quickly can use the biomarkers and SDK
- Raw Data
- Unprocessed data you can build your own filters and algorithms on
- Biomarkers
- HR and HRV metrics extracted in the time and frequency domains
- SDK
- Integration environments for Android, iOS, Windows, and Linux

Plan your measurement duration around the analysis
Each metric needs a different minimum window to be computed reliably. Use these as reference values when designing a research protocol
1
Time-domain metrics
from 10 seconds
Metrics analyzing how heartbeat intervals vary over time
2
Frequency-domain metrics (excluding VLF)
from about 40 seconds
Metrics analyzing the frequency characteristics of heart rate variability
3
VLF-band metrics
from about 310 seconds
Metrics analyzing long-term change in the very low frequency band
Recommended measurement duration
- Quick check
- at least 40 seconds
- Full analysis
- about 310 seconds or longer recommended
- Precise analysis
- about 10 minutes or longer
Basic conditions for measurement quality
- Wear the sensor in firm contact with the skin
- Keep movement to a minimum while measuring
- Hold a stable posture
Results may vary with the individual's physiological state, the surrounding environment, and how the device is worn.
Five foundations that keep the research setup simple
Less to assemble — the measurement hardware, data processing, and integration tooling come together
Wireless, worn on the wrist
Collects data during everyday movement, without cable constraints.
Smart filtering
Corrects motion-induced noise so measurement can continue uninterrupted.
Raw data and biomarkers
Choose the output your study needs — raw signal, derived metrics, or both.
Purpose-built measurement apps
Run measurement and review data in an app matched to your research protocol.
Multi-platform SDK
Connects to your existing research systems and services across major operating systems.
Smart Noise Filtering solves the noise problem
Noise from everyday environments with movement is the biggest obstacle in biosignal research. EmoConnect minimizes it through Smart Noise Filtering, collecting high-quality data continuously at a lossless 50 Hz sampling rate.

Synthetic demonstration data. It does not represent a product test result or a measured noise-reduction rate.
Apps for each research and development purpose
Dedicated apps matched to the nature and purpose of your work take you from measurement through to reviewing the data.
Raw data provided
Unprocessed data is delivered as measured, so you can develop your own algorithms and analyze freely.
SDK provided
SDKs for major platforms connect straight into your existing systems and services.
