The Best Polygraph – High Quality with 4 sensors and 5 Signals

Polygraph.BiO 4 sensors is a great product that was developed by Polygraph experts, which has adopted the newest and advanced technologies in the polygraph industry. 

Polygraph.BiO contains data acquisition hardware inside a plastic box and firmware embedded software for reading and decoding biological signals from the human body. The firmware transmits the signals and analysis to a windows PC or Android mobile. This hardware reads data from 4 different sensor as a real-time values with the transmission rate of 2400 bytes per second.     

When you connect the Polygraph.BiO hardware to the Android devise 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. When using the Polygraph.BiO for the first time, the user need to activate the hardware from his PC. 

Functions and Features:

There are 4 different bio signals sensors, which reads 5 different signals from the human body.

We are doing these psycho physiology different analysis from the sensors:   

The PPG heart sensor:

• 1. The blood volume capacity in the finger – BVP (blood volume pulse amplitude that reflects the human fear level)  
• 2. HR heart rate 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 measures even very small changes of the BP that indicates fear, stress, pressure, fight or flight, etc .
• 4. HRV (Heart Rate Variability) time domain calculation and FFT spectrum analysis that provides 40 different psychophysiology and physiological indicators concerning 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: Measuring the human galvanic Skin Response with 2 electrodes that connected to 2 fingers (2 and 4) for the inspection of the sympathetic autonomic nervous system activity. The electric circuit is extremely sensitive and show values between 2000 to 60,000 in a very high-resolution measurements.

The Temperature Sensor: Measuring the peripheral skin temperature in 0.01 C resolution, when the skin temperature become lower - this is indicator for the general sympathetic nerve system state.

The Abdominal breathing sensor: A very sensitive stretch sensor based on rubber that measures the human abdominal breathing amplitude.

PC Software

• The PC software of the Polygraph.BiO enables to run a professional polygraph test - very simple to use - very sophisticated technology include updating sequential questions (cold questions, hot questions and control question).
• The tester can update during running the test any kind of surround or background or inside artifacts that influence the recorded signals and that’s include the "artifacts timing" signed with a specific background color to indicate the situation. 
• During the polygraph test, all the raw data signals from the sensors and the analysis data concerned 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 not only display the whole process on the PC screen, clearly showing the subject’s psychological movements, also enables load history tests and everything can be send to anyone that has our platform or as excel files for "second opinion" analysis.

• Polygraph.BiO Android APP enables your device (Android system) 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 display the raw data from the sensors on the phone screen, and sends all  the signals to our cloud database servers. The Android APP is not a Polygraph test APP, it is data collection, display graphs and save on the cloud the signals.
