BrainBit Callibri sensors

BrainBit Callibri Sensors – Wireless Multifunctional Biosignal Sensor

BrainBit Callibri Sensors is a compact, wireless system designed to record various physiological signals and movement parameters.
A single Callibri module can be used to measure EEG, ECG/EKG, EMG, GSR, respiration, and movement parameters, depending on the equipment, electrodes, and measurement configuration used.
EEG (Electroencephalography) records the electrical activity of the brain.
ECG/EKG (Electrocardiography) records the electrical activity of the heart and uses the signal to analyze HR and HRV.
HR (Heart Rate) refers to the heart rate.
HRV (Heart Rate Variability) refers to the variability of heart rate.
EMG (Electromyography) measures the electrical activity of muscles and analyzes their tension and relaxation. GSR (Galvanic Skin Response), also known as electrodermal conductivity, can be used to observe changes in skin conductance related to, among other things, body arousal.
Respiration measurement allows for monitoring breathing frequency and rhythm using an appropriate accessory.
For EEG measurement, Callibri can operate as a single-channel brain activity sensor.
The system can be used in scientific research, biofeedback, neurofeedback, psychophysiological studies, education, sports, movement analysis, and for developing custom applications using biosignals.
Its small size and wireless data transmission allow for measurements both in the laboratory and outside of a traditional research setup.
The sensor communicates with a computer, smartphone, or tablet via Bluetooth Low Energy.
Callibri can transmit recorded data in real time to a compatible application.
Up to eight Callibri sensors can be used simultaneously, allowing for the creation of more complex measurement configurations. Multiple sensors can be used, for example, to simultaneously monitor different muscle groups or physiological parameters.
The manufacturer offers accessories that allow you to customize Callibri for a specific measurement type, including disposable electrodes, EEG electrodes, an ECG/HRV belt, a breathing belt, and GSR electrodes/clips.
Callibri is an open platform for developers – the manufacturer provides a free SDK enabling direct access to the device's data and integration with custom software.
The device is intended primarily for research, education, training, wellness, and the development of new applications.
The manufacturer describes Callibri as a non-medical product, not intended for the diagnosis or treatment of diseases.

Software Required for Operation

Callibri does not require a single, mandatory paid software program from the manufacturer. Compatible software that supports the Callibri sensor is required to receive, display, or process data.
The basic solution for device integration is the free Callibri/BrainBit SDK provided by the manufacturer.
The SDK (Software Development Kit) allows you to search for the device, connect to it, configure parameters, and receive measurement data.
The SDK includes a portable core written in C++ and libraries/wrappers enabling the device to be used on various platforms.
Supported systems include Windows, macOS, Linux, Android, and iOS.
The manufacturer provides tools for .NET/C#, C++, Java, Python, React Native, and Unity, among others.
The SDK allows you to create your own research, biofeedback, neurofeedback, fitness, wellness, and systems utilizing recorded biosignals applications. To use Callibri, it's not necessary to develop your own app – the device can also work with existing, compatible BrainBit software.

NeuroFit PRO

BrainBit officially designates NeuroFit PRO as compatible software for Callibri sensors.
NeuroFit PRO is designed for conducting biofeedback and neurofeedback sessions.
It supports the use of Callibri to measure EMG, HRV, GSR, and respiration, among other things.
It enables real-time parameter monitoring.
It enables standardized training sessions.
It provides training protocols and games using biofeedback/neurofeedback.
