Description

The Muscle BioAmp Patchy v0.2 leverages Upside Down Labs’ proprietary BioAmp sensing technology to provide a robust platform for electromyography (EMG). Its core is a precision instrumentation amplifier with an ultra-high input impedance of 10^12 Ω, ensuring accurate capture of microvolt-level biopotentials without signal attenuation. The onboard analog signal chain includes a fixed gain stage and a bandpass filter, outputting a conditioned signal ready for ADC conversion.

Designed for wearable human-computer interface (HCI) applications, the module’s compact form factor and direct electrode connection simplify integration into prosthetics, rehabilitation devices, and gesture control systems. It operates from a single 5V supply and includes reverse polarity protection and a power indicator for reliable field use.

Key Features

  • Precision BioAmp Technology: Ultra-high 10^12 Ω input impedance ensures minimal signal distortion from electrode-skin interface.
  • Optimized Signal Conditioning: Fixed x2420 gain and 72–720 Hz bandpass filter isolate and amplify the EMG frequency band.
  • Wearable Patch Design: Compact 4.7 x 1.4 cm module snaps directly to disposable gel electrodes (positive, negative, reference).
  • Broad Development Board Compatibility: Works with any microcontroller ADC (Arduino, ESP32, STM32, Raspberry Pi Pico, etc.).
  • Robust Onboard Protections: Includes reverse polarity protection and a clear power-on LED indicator.
  • Open-Source Platform: Full hardware schematics and software libraries provided for complete project customization.
  • High-Value Build: Durable construction with clearly labeled connectors for reliable prototyping and deployment.

Applications

  • Wearable prosthetics and rehabilitation device control via real-time muscle signal monitoring.
  • Gesture-based human-computer interfaces (HCI) for gaming, VR, and assistive technology.
  • Biomedical research and education platforms for studying muscle activity and fatigue.
  • Integration into sports science equipment for analyzing athletic performance and technique.
  • Prototyping of myoelectric control systems for robotics and animated art installations.

Frequently Asked Questions

What is the required input voltage for the Muscle BioAmp Patchy?

The module requires a 5V DC power supply, with a minimum operating voltage of 4.5V. It includes reverse polarity protection to safeguard the circuitry during connection. Ensure your development board or power source can provide a stable 5V rail.

How do I connect the Patchy to my microcontroller (e.g., Arduino or ESP32)?

Connect the module's analog output pin to an ADC input on your microcontroller. The provided Jumper cables attach to the onboard snap connectors. You must also connect the positive, negative, and reference electrodes to the human subject. The open-source library provides example code for signal reading and processing.

What type of electrodes are compatible with this EMG sensor?

The module is designed for use with standard disposable Ag/AgCl gel electrodes. The package includes two packs of three 'Boxy' gel electrodes. The onboard snap connectors accept the standard electrode tabs, creating a secure connection for the positive, negative, and reference channels.

Can I use this sensor for other biopotentials besides EMG?

The Patchy v0.2 is specifically optimized for the frequency range and signal amplitude of surface electromyography (EMG). Its fixed 72–720 Hz bandpass filter makes it unsuitable for lower-frequency signals like ECG or EOG without significant hardware modification. It is recommended for EMG applications only.

Is calibration required before using the Muscle BioAmp Patchy?

No manual calibration is required due to its fixed-gain analog design. However, you should calibrate the software scaling in your code by recording baseline noise (muscle at rest) and maximum signal values. The consistent gain of x2420 allows for reliable relative signal strength measurements across sessions.
