Callibri Sensors - Wireless Multimodal Biofeedback

Compact sensors that capture ECG, EMG, GSR, respiration, and motion streamed over Bluetooth for research, wellness, education, and R&D.

Beyond EEG, BrainBit builds Callibri - a wireless, multimodal hardware platform for neuro- and biofeedback, muscle activity tracking, and dental research workflows, with an open SDK for custom apps. Designed for research, education, and training, Callibri brings ECG/EMG/GSR/respiration and motion signals into one compact device, so teams can prototype faster, run repeatable sessions, and integrate data into their own analytics.

Callibri is intended for research, education, training, and wellness. It is not a medical device and is not intended to diagnose, treat, or cure.

A turnkey biofeedback workflow using Callibri sensors - start to finish.

Multitask sensor

Callibri is a tiny device able to registrate ECG, EMG, EEG, GSR and respiration, also equipped with accelerometer and angular velocity sensors. Was created to monitor physiological data on muscle movement and tension, breathing & heart rate during biofeedback sessions.

Electromyostimulation

Another version of Callibri is an electromyostimulation device with MEMS on board. The device allows you to issue pulses with a frequency of up to 100 Hz, bipolar pulses with ideal amplitude characteristics. The free advanced SDK helps you quickly integrate electrical stimulation into third-party applications and systems.

SDK and accessories

Callibri SDK is a set of libraries for different operating systems and platforms providing a full set of tools needed for configuring and receiving data from Callibri hardware platform. Large variety of compatible accessories as chest belt for ECG/HRV tracking, dry EEG electrodes and helmets, respiration belt with with tensiometric sensor, GSR clips allow you to get high quality recordings.

Designed for Modern Biofeedback Workflows

Callibri brings clean, wireless acquisition to everyday programs whether you’re building stress-reduction routines, breath training, posture feedback, or movement-aware sessions. Use it standalone or as part of a BrainBit + Callibri stack to combine brain and body signals in one workflow.

Movement & stress monitoring programs
Breath pacing and posture feedback
Education, labs, and demonstrations
R&D prototypes and developer projects

What Callibri Measures

ECG (heart activity) - track heart signal patterns for HR/HRV analysis.
EMG (muscle activity) - observe activation, tension, and relaxation timing.
GSR (skin conductance) - monitor arousal and stress-related changes.
Respiration - measure breathing rate/rhythm for pacing protocols.
EEG (single-channel) - basic brain-activity tracking for feedback and synchronization.
Motion - accelerometer & angular velocity for posture and movement cues.
