BioSignals 4-Sensor Polygraph System with Integrated AI

A complete professional polygraph system combining four physiological sensors, Windows software, mobile connectivity, CSV data export, and an integrated ChatGPT AI-assisted workflow.


Four Physiological Sensors in One System

The BioSignals 4-Sensor Polygraph System records four physiological channels simultaneously, providing the examiner with a clear, synchronized view of pulse activity, skin conductance, skin temperature, and breathing movement.

  • PPG/BVP Finger Sensor: Records the finger pulse waveform and supports heart rate, inter-beat interval, and heart rate variability analysis.
  • GSR/EDA Sensor: Records changes in skin conductance through two finger electrodes.
  • Skin Temperature Sensor: Records peripheral skin-temperature changes throughout the examination.
  • Breathing Sensor: Records respiratory movement through an adjustable breathing belt.

Integrated ChatGPT AI Assistant

BioSignals integrates ChatGPT assistance into the professional polygraph workflow. The AI Assistant can support both the preparation stage and the post-session review process.

Before the Examination

Enter the relevant case details into a structured questionnaire. ChatGPT can then help prepare an organized, case-specific question sequence, including introductory, relevant, comparison, and follow-up questions.

After the Examination

Export the recorded session data to CSV and use AI-assisted review to examine the physiological signals, identify notable response patterns, organize observations, and support a deeper professional review of the session.

The examiner remains in control: all proposed questions, observations, and interpretations must be reviewed and approved by the professional user.

Professional Windows Software

The included Windows software provides the tools required to conduct, record, review, and document structured polygraph sessions.

  • Display all four physiological signals in real time
  • Create and manage sequential polygraph question sets
  • Record complete examination sessions
  • Review synchronized raw signals and calculated data
  • Adjust recording and display settings
  • Export session data and analysis files to CSV
  • Preserve recordings for later professional review

USB, BLE and Mobile Connectivity

Use the system with a Windows PC through USB or connect through supported BLE and mobile configurations. Android OTG connectivity is also supported, while the BioSignals mobile apps allow compatible Android and iPhone devices to display and record physiological signals.

A Windows PC is required for the initial product activation.
