BioSignals Blue Box 4-Sensor Polygraph System with AI

Set up a focused four-sensor polygraph workstation with the BioSignals Blue Box. Pulse, skin conductance, temperature and abdominal breathing are combined with PC recording software and an integrated ChatGPT AI Assistant.

Integrated ChatGPT AI Assistant

BioSignals brings ChatGPT assistance into the polygraph software workflow. Use case details to help prepare a structured questionnaire and question sequence before the session. After recording, use AI-assisted review to explore the session data and organize observations. The examiner reviews the proposed questions and interpretation throughout the process.

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.

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

Activate the unit on a Windows PC before first use. Connect to the PC by USB. The Android app supports live signal viewing and cloud recording through an OTG connection.
