Key Features

Professional-Grade EMG Signal Processing

The onboard analog front-end handles the entire signal chain - from raw microvolt-level muscle signals to a clean, amplified analog output your microcontroller can read directly. Includes instrumentation amplifier, bandpass filtering, full-wave rectification, and envelope smoothing.

Adjustable Sensitivity

A precision onboard potentiometer lets you fine-tune gain to match different muscle groups, skin types, and electrode placements. Whether you're reading a gentle finger flex or a full bicep contraction, you can calibrate for optimal signal-to-noise ratio.

Plug-and-Play with Arduino & Beyond

Connect the output pin to any analog input on your microcontroller. Read muscle intensity with a simple `analogRead()` - no complex libraries or external ADCs required. Works seamlessly at both 3.3V and 5V logic levels.

Medical-Grade Electrodes Included

Ships with disposable Ag/AgCl gel electrodes that provide reliable skin contact and low impedance. The snap-style connectors ensure secure attachment during movement-intensive applications.

Compact & Embeddable Design

The small form factor makes it easy to integrate into wearable devices, prosthetic limbs, exoskeletons, and portable biomedical instruments.

How It Works

1. Electrode Placement - Attach three adhesive electrodes to the target muscle group: two along the muscle belly and one on a bony reference point (e.g., elbow or wrist).
2. Signal Acquisition - The sensor detects microvolt-level electrical potentials generated during muscle contraction through the skin surface.
3. Amplification & Filtering - The onboard instrumentation amplifier boosts the signal while the bandpass filter removes motion artifacts and power-line noise.
4. Rectification & Smoothing - The raw EMG signal is full-wave rectified and envelope-detected, producing a smooth analog voltage proportional to muscle contraction intensity.
5. Microcontroller Reading - Feed the output into any analog pin. Stronger contractions produce higher voltage readings, giving you direct proportional control.

Project Ideas

Bionic / Prosthetic Hand Control

Build a robotic hand that mimics your real hand movements. Map EMG signals from forearm muscles to servo positions, creating an affordable myoelectric prosthetic prototype for research or assistive technology development.

Gesture-Controlled Robot

Control a wheeled robot, robotic arm, or drone using muscle flexion patterns. Flex your bicep to move forward, clench your fist to grip - create intuitive human-robot interfaces without joysticks or buttons.

Rehabilitation & Physical Therapy Monitor

Track muscle activation levels during exercise or recovery. Log contraction strength over time, set threshold-based feedback alerts, and create visual biofeedback displays to help patients regain motor function.

Human-Computer Interaction (HCI) Research

Explore novel input methods - control a cursor, play video games, type on a virtual keyboard, or navigate menus using muscle signals. Ideal for accessibility research and alternative communication devices.

Biomedical Engineering Coursework

Study real EMG waveforms, analyze frequency content, experiment with digital filtering algorithms, and understand the electrophysiology of skeletal muscle contraction in a hands-on laboratory setting.

Exoskeleton & Wearable Robotics

Integrate multiple muscle sensors to detect movement intent across several muscle groups. Use the data to drive actuators in powered exoskeletons, assistive braces, or augmented-strength wearable devices.

Fatigue Detection System

Monitor the spectral shift and amplitude decline in EMG signals during sustained contraction to build systems that detect muscle fatigue - useful in ergonomics, sports science, and workplace safety.

Art & Music Installations

Transform muscle activity into sound, light, or visual art. Map contraction intensity to synthesizer parameters, LED brightness, or generative graphics for interactive installations and performances.
