Sure you wear it on your wrist, but two electrocardiogram (ECG) sensors for monitoring heart health are your first hint at the snoring dragon packed inside this mild-mannered form-factor.

And because it’s also quite simple to implement the required sensors, it makes sense that electrocardiogram (ECG) machines are a popular choice among introductory medical electronics projects.

The Polar H10 Heart Rate Sensor was the top-performing chest-strap monitor we tried. Throughout testing we found the real-time ECG/EKG monitoring accurate, and we loved that the ANT+ connectivity ...

Scientists have demonstrated that skin conductance can help measure our core emotions. It's only a matter of time before EDA ...

sensors, a digital stethoscope, and an EKG sensor. The stethoscope uses a piezoelectric disc to measure acoustic noise from your body and turn it into an electric reading that BeamO can understand.
