BioAmp EXG Pill

Professional-grade analog front-end amplification for ECG, EMG, EOG, and EEG biosensing on one tiny board

This project is coming soon. Sign up to receive updates and be notified when this project launches.

BioAmp EXG Pill is a small, powerful Analog Front End (AFE) biopotential signal acquisition board that can be paired with any 5 V Micro Controller Unit (MCU) with an ADC. It is capable of recording publication-quality biopotential signals like ECG, EMG, EOG, and EEG, without the inclusion of any dedicated hardware or software filters. It’s small size allows easy integration into mobile and space-constrained projects, and it’s powerful noise rejection makes it usable even when the device is close to the AC mains supply. Any 1.5 mm diameter wire can be used as a strain-relieving electrode cable, making BioAmp EXG Pill very cost-effective in comparison to other options.

What Can It Be Used For?

BioAmp EXG Pill is a one-stop solution for researchers, tinkerers, and hobbyists who are looking for novel biopotential amplification. Thus, it can be used for a wide variety of interesting biosensing projects:

  • AI-assisted congestive heart failure detection using CNN (ECG)
  • Heart Rate Variability calculation for heart ailment detection (ECG)
  • Prosthetic arm (servo) controller (EMG)
  • Palsy physical therapy quantitative analysis device (EMG)
  • Real-time game controller (EOG)
  • Controlling LEDs via brain waves (EEG)
  • Patient monitoring device

And many more…

Versatile Design Means A Variety Of Applications

The elegant design of this board allows it to be used in 3 ways:

  • Pin Header Holes allow you to solder on header pins (berg strip) for easy breadboard use
  • Castellated Holes allow you to solder BioAmp EXG Pill directly onto your custom PCB to add biopotential amplification capabilities
  • Electrode Holes allow you to use any 1.5 mm diameter wire as electrode cable with minimal strain
