The BioAmp by Upside Down Labs can help! The project is open source hardware and the design files are available at upsidedownlabs/BioAmp_v1.5:
BioAmp v1.5 is a single chip Bio-potential amplifier for recording any Bio-potential signal non-invasively. It’s compatible with Backyard Brains Spike Recorder, which you can use to record and visualize all the Bio-potential signals.

Upside Down Labs has designd a small, open source bio-potential amplified:
BioAmp EXG Pill is a small and elegant BioPotential board that you can use with any 5v micro with an ADC. It can be used to record research-grade ECG, EMG, EOG, and EEG without incorporating any filtering circuit/code!
Upside Down Labs has this neat kit on Tindie that lets you listen to your muscles!
BioAmp v1.5 is a single chip biopotential amplifier. It can record any biopotential signal non-invasively and doesn’t require any microcontroller to sample the signal. You just plug 9v Battery to board, Electrodes to body and Audio jack to Mobile/Laptop and you are ready to record signals like EMG, ECG, EOG, and EEG. You can record the signals on a pc using audacity OR on mobile using Backyard Brain’s spike recorder app.
