<p>If you really want to listen to your pulse then try Marco
Donnarumma's Xth Sense:</p>
<p><a class="moz-txt-link-freetext" href="https://marcodonnarumma.com/works/xth-sense/">https://marcodonnarumma.com/works/xth-sense/</a></p>
The sound it can produce is very rich, probably not what you want if
you're just after a click track.<br>
<p><br>
</p>
<p>If you'd rather pick up the electrical signals directly from your
muscles, including the heart, then you need an ECG /
electrocardiogram, or EMG / electromyogram like the Myo or
Bitalino. Or EEG / electroencephalogram for your brain. The
signals are in the form of pulse trains up to around 200Hz.</p>
<p>ECG : 0.05 – 150Hz<br>
EEG : 0.05 – 70Hz<br>
EMG : 7Hz – 20Hz<br>
</p>
<p>With dry electrodes you'll pick up signals in this range:</p>
<p>ECG : < +/- 2.5mV<br>
EEG : +/- 10uV to 100uV<br>
EMG : +/-50uV to 30mV<br>
</p>
<p>The electrodes will also have a variable DC offset up to +/-
300mV or so, which makes it all the more challenging to capture a
good signal.<br>

<div>Deriving an electrical/rectangular click/pulse <i>is</i>
the goal - but I'm not sure what types of transducers would
make for a good solution to this. Is there something with a
very sensitive electrode and a really perfectly-tuned
comparator? </div>
