Welcome to SiFi Labs Documentation

SiFi Labs designs and manufactures research-grade wearable biosensors for physiological monitoring, gesture recognition, and human-computer interaction research.

Our Mission​

We believe researchers deserve complete control over their data. That's why all SiFi Labs devices provide:

  • Open Data Access - Raw sensor data with no proprietary formats or cloud lock-in
  • Privacy First - All data stays on your hardware
  • Research Grade - High sampling rates and clinical-quality signals used in peer-reviewed studies

Key Features​

Complete Data Ownership​

Your research data belongs to you. All SiFi Labs devices work completely offline with no cloud services, no data uploads, and no tracking. Export raw data in standard formats and use any analysis tools you prefer.

Multi-Modal Sensing​

Our devices integrates multiple sensors with hardware-synchronized data acquisition:

  • ECG - Cardiac monitoring at 500 Hz
  • EMG - Muscle activity (1-8 channels depending on device)
  • EDA - Electrodermal activity at 50 Hz
  • PPG - 4-wavelength photoplethysmography at 100 Hz
  • IMU - 6-axis motion tracking at 100 Hz
  • Temperature - Skin temperature at 1 Hz

Real-Time Biofeedback​

Programmable LEDs and vibrotactile motors enable:

  • Haptic biofeedback experiments
  • Event markers
  • User notifications
  • Custom interaction patterns

Open Integration​

Stream data to your preferred tools:

  • Lab Streaming Layer (LSL) - Integrate with EEGLAB, OpenViBE, and more
  • Network Streaming - TCP/UDP for custom applications
  • File Export - Direct CSV output
  • Python API - Build custom pipelines and analysis tools

Getting Started​

If you are new to SiFi Labs, take a look at our devices.

If you already have a device, we recommend using SiFi Bridge to quickly get started.
