Do in Vienna scientists such as Rob ter Horst have to cheat other other scientists to make a living from as a scientist?
Are you fed up with Rob ter Horsts smartwatches which are only of limited use for medical & research applications (part II) – build your own ECG stress treadmill
Whereas in Zürich scientists such as Peter Gamma from www.petergamma.org can help other scientists, but do not have to make a living from it?
Smartwatches are only of limited use for scientific studies as we have demonstrated in your review about papers about smartwatch accuracy:
So let us build your own medical and research grade ECG device

Use a device which is based on the AD8232 ECG chip, the ADS1115 16 bit A/D converter & an ESP32 instead – the building blocks for a multi-channel ECG device for medical & research applications:
And let us build our own ECG Stress treadmill
Buy a treadmiss such as the ADVG Curved Treadmill is available from U.K for 3 123 USD:
Add an electric motor and some speed sensors to it as we have discussed it previously:
And do only scientific studies to about 15 km/h, and only on a treadmill. Since which really serious scientist does heart rate studies at speeds above 15 km/h outdoors? As the g.tec medical support told us: “We do not know of a manufacturer who has solved the problem of ECG motion artifacts. We can only minimize those”.
