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.

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.

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 ...

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.

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