Polygraph.BiO 6 sensors is a great product that was developed by Polygraph experts, using cutting-edge technologies.

Polygraph.BiO contains data acquisition hardware inside a 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. This hardware reads data from 6 different sensors as real-time values with a transmission rate of 2400 bytes per second.     

To connect the Polygraph.BiO hardware to the Android device, you need to use OTG USB cable. Each Polygraph.BiO has its own serial numbers inside the hardware, preventing the possibility of faking the product. To use the Polygraph.BiO for the first time, you need to activate the hardware from his PC. 

Functions and Features:

The device has 6 different physiological bio signals sensors, which reads the human body signals, and analysis of the psycho-physiology parameters as follows:   

1. The blood volume capacity in the finger – BVP (blood volume pulse amplitude that reflects the human fear level)  

2. Heart Rate (HR) and IBI (Inter Beat Interval in MSEC, increasing the pace - measure pressure and stress - fight or flight syndrome).

3. Dynamically relative blood pressure changes that measure even the smallest changes of the BP that indicates fear, stress, pressure, fight, and flight.

4. HRV (Heart Rate Variability) time domain calculation and FFT spectrum analysis that provides 40 different psychophysiology and physiological indicators concerning the mental and emotional state of the autonomic nervous system activity. The most 4 common parameters are: "Rumination thoughts" (VLF), "Stress activation" (HF), "relax activation" (LF), "calm ratio" (LF/HF).

The GSR sensor is used for measuring the human galvanic Skin Response with 2 electrodes connected to 2 fingers (2 and 4) for the inspection of the sympathetic autonomic nervous system activity. The electric circuit is extremely sensitive and shows values between 2000 to 60,000 in very high-resolution measurements.

The Temperature Sensor helps in measuring the peripheral skin temperature in 0.01 C resolution when the skin temperature becomes lower, indicating the general sympathetic nervous system state.

The Abdominal breathing sensor is a very sensitive rubber-based stretch sensor that measures the human abdominal breathing amplitude.

The Chest breathing sensor is a highly sensitive rubber-based stretch sensor that measures the human chest breathing amplitude.

The Air pressure sensor (anti cheat sensor) is a seat pad of "air pressure input" sensor, with very sensitive, high resolution and fast response that can measure any kind of "human body movement”. 

PC Software

• The PC software of the Polygraph.BiO enables the customer to run a professional polygraph test using a simple and sophisticated technology that include updating sequential questions (cold questions, hot questions and control question).
• The tester can update any kind of surrounding or background or inside artifacts that influence the recorded signals during the test. 
• During the polygraph test, all the raw data signals from the sensors and the analysis data concerning the questions and answers will be recorded and will be saved for future review. The customer also can export all the data to .CSV files for his own analysis.
• Polygraph.BiO software displays the whole process on the PC screen, clearly showing the psychological signals, and also enables the PC to load the test history which can be sent to anyone that using the same platform or as excel files. 
• Polygraph.BiO Android APP enables your Android to read data from the hardware via a dedicated communication OTG cable. The Android device will be used as the power supply for the hardware and as a display screen for showing the subject body’s information.
• The APP has all the line charts that display the raw data from the sensors on the phone screen and sends all the signals to our cloud database servers.
