Polygraph.BiO NANO is a great product developed by polygraph experts using cutting-edge technologies.

Polygraph.BiO comprises data acquisition hardware inside a 3D-printed PLA plastic box for reading and decoding biological signals from the human body. It also contains firmware-embedded software that transmits the signals and analysis to a Windows PC or Android mobile device. This hardware reads data from 2 different sensors as real-time values with a transmission rate of 2400 bytes per second.

To use the Polygraph.BiO hardware efficiently, connect it to an Android device using an OTG USB cable. Each unit has a unique serial number programmed inside the hardware to prevent counterfeiting. Initial activation must be conducted on a PC.

Functions and Features:

The device contains 2 different physiological bio signal sensors, which read human body signals and analyze psychophysiology parameters as follows:

• Blood Volume Pulse (BVP): Measures blood volume in the finger, indicating fear levels.
• Heart Rate (HR) and Inter Beat Interval (IBI): Monitors heart rate and stress indicators, including fight-or-flight responses.
• Dynamic Blood Pressure Changes: Detects minute BP variations related to fear, stress, and pressure.
• Heart Rate Variability (HRV): Provides 40 psychophysiological and physiological indicators through time domain calculations and FFT spectrum analysis, including "Rumination thoughts" (VLF), "Stress activation" (HF), "Relaxation activation" (LF), and "Calm ratio" (LF/HF).
• GSR Sensor: Measures galvanic skin response via electrodes on fingers, indicating sympathetic nervous system activity with high-resolution readings (2000-60,000).
• Temperature Sensor: Measures high resolution skin temperature. 
• Breathing belt Sensor: Measures the breathing movements with a stretch sensor.

PC Software Capabilities:

• Run professional polygraph tests using sophisticated technology, including updating sequential questions (cold, hot, and control questions).
• Customize settings to account for environmental factors affecting signal quality.
• Record and save raw data and analyses for future review, with export options to .CSV for personal analysis.
• Visualize the polygraph process on PC, with data sharing and export capabilities.

Android and iPhone App Features:

• Connects the device via BLE or OTG cable, you can also use your Android device as a power supply and display screen.
• Displays real-time data from sensors on your phone, with cloud-based data storage.
