Description
What is the Callibri Biofeedback Sensor?
Callibri is a comprehensive biofeedback sensor that bridges the gap between your body and your training. Unlike standard fitness trackers that only count steps, Callibri is equipped with multiple clinical-grade sensors to monitor muscle movement, tension, breathing, brain activity, and heart rate.
But it doesn’t just read data—it converts it into readable, actionable information via Bluetooth. Whether you are using it to monitor muscle activity, reading brain waves for sleep optimization, or utilizing its electrostimulation (EMS) capabilities for pain relief and recovery, Callibri is the ultimate all-in-one tool for fitness, wellness, and rehabilitation.
Callibri brings clean, wireless acquisition to everyday programs, whether you’re building stress-reduction routines, breath training, posture feedback, or movement-aware sessions.
Biofeedback in Action: Training as a Game
The best way to stick to a training or recovery plan is to make it fun. Because Callibri is a true biofeedback system, it translates your physiological data into engaging, interactive experiences.
Introducing Muscle Games:
Why just look at graphs when you can play? Callibri’s biofeedback software allows you to race, play, and compete by flexing your muscles. Players must progress through a running maze by appropriately flexing their muscle. As the player applies more tension, the runner’s speed increases. To add more difficulty, a monster who chases the runner can be introduced, forcing the player to react more quickly. This gamified biofeedback is not just entertaining—it helps you build a precise mind-muscle connection faster than traditional, boring exercises.
Technology: One Device, Six Modalities
Why buy multiple devices when one Callibri biofeedback sensor can do it all? The device intercepts electrical activity from the body and transmits it for calculation. Here is what each biofeedback sensor brings to the table.
1. EMG Sensor (Muscle Activity Tracking & Exercising)
The EMG sensor (or EMG muscle sensor for EMG biofeedback) analyzes muscle activity, providing accurate data that can be converted and used to monitor and plan exercises. Callibri sensors can work individually or network with each other and coordinate with other biofeedback sensor types.
Callibri features a fixing system that eliminates interference, providing users with reliable information about their body activity, muscle tension, overstrain, and symmetrical effort.
Medical: future opportunities
With additional electrodes connected through USB, Callibri reads activity from smaller or hard-to-access muscles, which can be used in medical treatments like pelvic floor training and dentistry.

2. EEG Sensor (Brain Activity)
BrainBit’s wireless Callibri sensor creates a practical solution for mobile brain activity monitoring. Take EEG beyond traditional laboratory environments and into real-world scenarios. Whether you are a researcher, educator, or developer, this sensor allows you to capture high-quality brainwave data without being tethered to bulky, stationary equipment.
Here is how this EEG sensor is used in the field.
- Research & Neuroscience: Collect EEG data during cognitive studies, behavioral experiments, and real-world observation projects.
- Education & Training: Create engaging neuroscience demonstrations and hands-on learning experiences for students.
- Neurotechnology Development: Build and test EEG-powered applications, brain-computer interfaces (BCIs), and interactive systems.
- Human Performance Research: Study attention, engagement, workload, and cognitive states in natural environments.
- Field & Outdoor Studies: Monitor brain activity during activities that are difficult to evaluate using traditional stationary EEG systems.
- Neurofeedback & Sleep: Use the sensor for relaxation training, focus enhancement, and accurate sleep tracking via a Callibri-based sleep patch (in development).
3. ECG & HRV Sensor (Heart Rate & Variability)
The ECG sensor tracks heart rate and Heart Rate Variability (cardiac activity). HRV is a key marker of your autonomic nervous system—it tells you if you are ready to train hard or if you need to recover.
Use Case: Stress management, recovery tracking, and sleep phase analysis.
4. Respiratory Sensor (Breathing)
Monitors your breathing patterns and rate. Breathing is the fastest way to influence your nervous system.
Use Case: Breath training, relaxation exercises, and stress reduction.
5. MEMS (Accelerometer & Angular Velocity)
Tracks movement, counts reps, and measures angular velocity. This provides context for your physiological data.
Use Case: Movement tracking, rep counting, and Smart Gym integration.
6. EMS (Electrostimulation)
Callibri offers two functionality options: it can sense muscle activity or stimulate it. Electromyostimulation can be used for various purposes, including muscle relaxation, stimulation for better training, and even as a preventive measure against muscular disorders.
Use Case: Post-workout recovery, muscle re-education, and speeding up the healing of sprains and soreness.
Supported Software: Record, Review, Train, and Integrate
The Callibri hardware is powered by a complete ecosystem of software designed for every type of user:
- NeuroFit PRO (by BrainBit): A guided neurofeedback suite for teams, clinics, and practitioners. It includes ready-made protocols for focus, relaxation, and resilience; live metrics with progress tracking; a custom session builder; and 38 colorful neurofeedback games.
- Callibri Biofeedback & Callibri BeFit Apps: Designed for home and mobile users on iOS and Android. These apps provide engaging, game-like visual feedback for muscle training, rehabilitation, and specialized pelvic floor training.
- Open SDK for Developers: We provide an open, free SDK (Software Development Kit) with wrappers for Java (Android), C++, iOS, Windows, and Unity. This allows you to build custom mobile and desktop applications, integrate with smart gyms, or conduct advanced research.
The Power of Combination: How Multi-Sensor Biofeedback Multiplies Your Results
This is where Callibri truly outperforms single-purpose devices. By combining sensors, you can train multiple physiological systems simultaneously, creating a synergistic effect that accelerates results faster than training one system alone. Research in multimodal biofeedback shows that integrating signals like EEG, HRV, and EMG can effectively modulate emotional and attentional states for peak performance.
Here is how combining Callibri sensors can transform your training and recovery.
Combination 1: EMG + HRV + Breathing for Peak Athletic Performance
The Synergy: You can have perfect muscle activation (EMG), but if your heart is racing and your breathing is shallow (sympathetic nervous system dominance), your performance will suffer.
How It Works: By combining EMG, HRV, and breathing data, you can train for “Physiological Coherence.” You learn to maintain muscle tension while keeping your heart rate variability high and your breathing slow. This teaches your body to stay calm under pressure, improving precision and psychological stability during competition.
The Result: Faster reaction times, better mind-muscle connection, and delayed onset of fatigue.
Combination 2: EEG + HRV + EMG for Deep Relaxation and Sleep
The Synergy: Relaxation is not just a mental state; it is a physiological one. You can be mentally exhausted but physically tense (high EMG) and have a racing heart (low HRV), preventing you from falling asleep.
How It Works: Using EEG to down-train high-frequency brainwaves (quieting the mind), HRV to slow the heart, and EMG to release muscle tension creates a full-body relaxation response. Research indicates that combined EEG and HRV/respiratory training may significantly support sleep quality.
The Result: Faster sleep onset, deeper sleep phases, and a more complete recovery overnight.
Combination 3: EMG + Accelerometer for Injury Prevention
The Synergy: Looking at muscle activity (EMG) without seeing the movement (Accelerometer) can be misleading.
How It Works: By combining these two signals, you can see exactly which muscles are firing during specific ranges of motion. This is crucial for identifying compensatory movement patterns that lead to injury.
The Result: Safer training, corrected form, and targeted rehabilitation.
The Investment Value: At just $330 per biofeedback sensor, Callibri is incredibly cost-effective. Buying separate EMG, HRV, and EEG devices would cost you thousands. With Callibri, you can start with one sensor for your primary goal, and later add a second or third sensor (up to 8 can be connected simultaneously) to unlock these powerful combined protocols.
