BioSignals Finger device with 3  sensors is a great product that was developed by experts and has adopted the newest and most advanced technologies in the industry. 

BioSignals BSS-1 (tm) contains data acquisition hardware inside a plastic box for reading and decoding biological signals from the human body. Also contains firmware-embedded software that transmits the signals and analysis to a windows PC or Android mobile. This hardware reads data from 3 different sensors and 4 inputs as a real-time value with a transmission rate of 2400 bytes per second.     

Connecting the BioSignals BSS-1 (tm) to the Android device via BLE or with an OTG USB cable makes training and activating signal recording easy. Each BioSignals BSS-1 (tm) has its own serial numbers programmed inside the hardware, preventing the possibility of faking the product. When using the BioSignals BSS-1 (tm) for the first time, the user needs to activate the hardware by using a PC. 

Functions and Features:

The device contains 3 different physiological bio signals sensors, which reads the human body signals, and analysis the psychophysiology parameters as follows:

• The blood volume capacity in the finger – BVP (blood volume pulse amplitude that reflects the human fear level)  
• Heart rate (HR)  and IBI (Inter Beat Interval in MSEC, increasing the pace - measure pressure and stress - fight or flight syndrome).
• Dynamically relative blood pressure changes, which measures even very small changes of the BP that indicates fear, stress, pressure, fight, and flight.
• 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 is used to measure 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 a very high-resolution measurement.

The Temperature Sensor is helpful to measure 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: A highly sensitive rubber-based stretch sensor that measures the human abdominal breathing amplitude.

PC Software

• The PC software of  BioSignals BSS-1 (tm) enables the customer to run professional BioSignals training using a simple, sophisticated technology that includes updating sequential questions (cold questions, hot questions, and control questions).
• Customers can update any kind of surroundings, background, or inside artifacts while doing the training.
• During the training, all the raw data signals from the sensors and the analysis data concerned with the training stage are recorded and saved for future analysis and review. 
•   BioSignals BSS-1 (tm) software displays the whole process on the PC screen, clearly showing the psychological signals, and also enables the PC to load the training history which can be sent to anyone that using the same platform or as excel files. 
• BioSignals 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.
