BioSignals 5-Sensor Polygraph System

Bring pulse, skin conductance, temperature and two breathing channels into one professional recording setup. This five-sensor system combines portable hardware with Windows polygraph software for structured examinations and detailed session review.

What you can record

• PPG/BVP: records the finger pulse waveform and supports heart rate, inter-beat interval and HRV analysis.
• GSR/EDA: records changes in skin conductance through finger electrodes.
• Skin temperature: adds a peripheral temperature channel for session review.
• Abdominal breathing: records breathing movement with a stretch sensor.
• Chest breathing: adds a separate chest respiration channel.

Record, review and export

The Windows PC software displays live signals, supports sequential question workflows and saves recordings for later review. Review raw signals and analysis together, adjust session settings and export CSV data for further analysis and documentation.

Technical details

Data transfer rate: 2,400 bytes per second. PPG data supports heart rate, inter-beat intervals and HRV time-domain and frequency-domain analysis.

Setup and compatibility

Windows PC for initial activation and the examination software. Supports Bluetooth Low Energy and USB/OTG connectivity, with Android and iPhone apps for mobile signal viewing and recording.
