Moyo Monitor 

By Trish Kanana

The Moyo Monitor prototype is a speculative wearable device with two biosensors for heart rate and motion sensing. The device is intended to collect longitudinal Heart Rate Variability data which is then sent to The Tulia Band. This prototype compares two heart rate sensing methods - one being a photoplethysmography (PPG) signal and the other an electrocardiogram (ECG) signal. A PPG sensor “uses a light-based technology to sense the rate of blood flow as controlled by the heart’s pumping action”(NeuroSky 2015). While an ECG sensor “measures the bio-potential generated by electrical signals that control the expansion and contraction of heart chambers”(NeuroSky 2015). The Moyo Monitor  that uses the PPG sensor also uses a3-axis accelerometer for motion sensing.
